“Outside Sub-Saharan Africa, Homo sapiens are vermin, in the Australian sense — an introduced species with no co-evolved local predators”

Filed under: Africa, Asia, Australia, Economics, Europe, History, Science — Tags: , , , , — Nicholas @ 03:00

You have to admit that Lorenzo Warby has a way with words to introduce a new essay, yes?

Outside Sub-Saharan Africa, Homo sapiens are vermin, in the Australian sense — an introduced species with no co-evolved local predators. That means that their strongest selection pressures — both genetic and cultural — have almost always been about dealing with other humans.

We are the cultural species par excellence. Cultures can be reasonably thought of as collections of life-strategies. Culture tends to be persistent — aspects of culture can be highly persistent.

It is worth keeping in mind that genetic selection can occur surprisingly quickly — i.e., in a relatively short number of generations, depending on the intensity of the selection pressures. A very clear example of this is the evolution of lactase persistence in pastoralist, or agro-pastoralist, populations. (The decades-long experiment in domesticating silver foxes is an extreme example.)

The great advantage of cultural selection is that it is faster than genetic selection but culture still has to show some “stickiness”, some persistence, to be useful. Especially in the evolution of signals, norms and social strategies.

The regions where the local physical environment has been successfully managed longest — or most thoroughly — are Europe, particularly North-West Europe, East Asia and India (especially by high-jati Indians). So, those are the areas where natural and cultural selection has been most focused on selection for dealing usefully with other humans. Those populations have also been the most successful in dealing with the modern world, wherever they go. This hardly seems a coincidence.

The regions where dealing with the local physical environment has been most salient are Sub-Saharan Africa — all those co-evolved parasites, pathogens, predators and mega-herbivores — and Australia — which is full of deserts and spiky things likely to poison you. Much of Africa is also semi-desert forager lands, while the tsetse fly stopped the central African plains generating the equivalent of the connecting — for good or ill — pastoralist cultures of the Eurasian steppes. Both continental-scale regions therefore historically had low human population densities.

The consequence in Africa was that Sub-Saharan Africa has, for millennia, been a region of endemic slavery. Labour was more valuable than land, which led — as it usually did historically — to labour bondage: the violent/coercive extraction of labour’s scarcity value. In this case, the low population density meant that folk were regularly seized and transported, thus requiring the level of domination for folk to be moved at will — i.e., slavery rather than some form of serfdom.

Increased selection to deal with the physical environment meant comparatively less selection to deal with other humans. Sub-Saharan African and Australian Aboriginal populations have been rather less successful at dealing with the modern world than have other populations. (Claims about the success of recent African immigrants seem to be overstated.) The key element of the modern world is domination of social outcomes by human interactions to the greatest extent yet achieved in history. Again, that relative lack of success hardly seems like a coincidence.

Yes, it is true that selection for transportation across the Atlantic as slaves was negative in all sorts of senses. The churn of slavery massively undermined cultural transmission, the selection was for physical robustness and, if anything, against executive functions (which are highly heritable). Nevertheless, with the partial exception of recent African immigrants — who are selected for initiative and education — both populations have been markedly less successful than other groups.

There are certainly factors which affect that either way. Not inflicting on Australian Aborigines the dual metabolic disasters of the farming and processed-food revolutions at the same time would be good. Not under-policing the localities in which folk live is also good.

Nevertheless, there is no reason to think that capacities — which are a genetic, epigenetic and cultural matter — will be evenly distributed across all populations. Indeed, we have very good reasons to think that that will not be the case, due to the variations in selection pressures — whether genetic, environmental or cultural, including interactions between the three. It is not a good idea, for instance, to spend 1400 years marrying your cousins.

Even when means and medians are the same in the distribution of some trait across groups, differences in the size of tails — i.e. the number of extreme outliers — can lead to differences in the distribution of outcomes. Any population with a persistently larger tail of high physical robustness and lower executive functions — which can be an ethno-racial pattern but also a class pattern — will tend to have higher rates of violent crime. Conversely, any population with a smaller tail of lower executive functions — for example, East Asians with a long history of underclass males not breeding but selection for reproductive success through passing examinations and cooperative farming — will tend to have lower rates of violent crime.

Sufficient variance in traits — so having a larger “right tail” of positive-for-human-flourishing characteristics — can be enough on its own to increase a group’s success. Tail effects matter.1

The persistence of gene flows across human populations does undermine any strong notion of human subspecies among Homo sapiens. It does not imply equal distributions of capacities across human populations.

Hence, evolutionary thinking is neither comfortable nor comforting.

    1. Given that human males — like males across species — have a flatter distribution of traits — so more positive and negative outliers — having equal numbers of males and females at the top ends of hierarchies suggests some level of discrimination against males. Conversely, having female prison populations begin to approach male populations in size suggests some level of discrimination against, even persecution of, females.

Unravelling the actual origins of Covid (aka Wuhan Coronavirus)

Filed under: China, Government, Health, Politics, Science — Tags: , , , — Nicholas @ 05:00

In Spiked!, Matt Ridley outlines some of the more recent admissions-against-interest of the people who used to accuse you of tinfoil-hattism and peddling conspiracy theories when the topic of the origins of Covid came up:

Wuhan Institute of Virology.
Wikimedia Commons.

Two of the key figures in the story of Covid’s origins gave away vital new information last week before the US Congress.

One of these figures is Ralph Baric, the University of North Carolina professor who invented ingenious techniques for genetically altering coronaviruses. He effectively taught scientists at the Wuhan Institute of Virology in China how to do “gain of function” experiments with bat-derived sarbecoviruses to make them more infectious or lethal in humanised mice. The other figure is Peter Daszak, the highly paid president of the non-profit, EcoHealth Alliance. Over many years, EcoHealth Alliance has channelled large sums of US taxpayer money to the Wuhan Institute of Virology for “gain of function” experimentation, and for finding new sarbecoviruses in bats.

Up until now, Baric and Daszak have taken slightly different approaches to (hardly) helping the world understand what went on in Wuhan before the Covid-19 outbreak in November 2019. Baric has remained largely silent, refusing to do interviews or sign up to articles in the scientific press. He remained silent last week, too, but the Congressional Select Subcommittee on the Coronavirus Pandemic released the transcript of a lengthy closed-door session it held with him in January.

Daszak, by contrast, has adopted a high profile, organising round-robin letters defending his friends and colleagues in Wuhan, giving interviews, writing articles and getting himself appointed to not one but two commissions investigating Covid’s origins, despite a glaring conflict of interest. He appeared before the subcommittee on 1 May.

Both men reluctantly admitted under oath to points that markedly strengthen the already strong hypothesis that the pandemic began with an accident in a laboratory in Wuhan. But before considering what they said, it might be worth briefly looking at the relationship between the two.

In comments on a draft of a grant proposal written in 2018, which were made public last year, Daszak boasted of how cheap it is to do experiments in Wuhan because they use a lower biosafety level (BSL-2), without negative-pressure work cabinets. Baric responded that US scientists would “freak out” at that. So a newly released email Baric sent to Daszak on 27 May 2021 smacks one’s gob somewhat. Responding to Daszak’s insistence that the Wuhan Institute actually used safer versions of these low safety standards for its experiments, Baric wrote:

    Your [sic] being told a bunch of BS. Bsl2 [with] negative pressure, give me a break. There [sic] last paper mentioned bsl2 [with] appropriate PPE. This last part was the first and only time this was ever mentioned, never in earlier papers, and in the latest paper never defined either. I have no doubt that they followed state-determined rules and did the work under bsl2. Yes China has the right to set their own policy. You believe this was appropriate containment if you want but don’t expect me to believe it. Moreover, don’t insult my intelligence by trying to feed me this load of BS.

Baric clearly does not have a high regard for the Wuhan Institute of Virology’s safety standards, or indeed for his virus-hunting grantrepreneur colleague, Daszak. Nor do some other scientists who have nonetheless defended Daszak in public. Thanks to freedom-of-information revelations, we now know that “Dastwat” and “EgoHealth” are just two of the epithets used about him by his friends. With friends like that …

Both men still insist, however, that the pandemic began naturally – but, to borrow from Mandy Rice-Davies, they would say that wouldn’t they? Before the subcommittee, where even the Democrats gave him a pasting, Daszak was forced to concede some key points on which he had previously stonewalled or said the opposite.

Firstly, he had to concede that a lab leak was possible. Yet back in 2020, Daszak told Democracy Now that “the idea that this virus escaped from a lab is just pure baloney. It’s simply not true … So it’s just not possible.”

DNA and India’s caste system

Filed under: History, India, Religion, Science — Tags: , , , , — Nicholas @ 03:00

Earlier this month, Palladium published Razib Khan‘s look at the genetic components of India’s Caste System:

Though the caste system dominates much of Indian life, it does not dominate Indian American life. At slightly over 1% of the U.S. population, only about half of Indian Americans identify as Hindu, the religion from which the broader categories of caste, or varna, emerge. While caste endogamy — marrying within one’s caste — in India remains in the range of 90%, in the U.S. only 65% of American-born Indians even marry other people of subcontinental heritage, and of these, a quick inspection of The New York Times weddings pages shows that inter-caste marriages are the norm. While tensions between the upper-caste minority and middle and lower castes dominate Indian social and political life, 85% of Indian Americans are upper-caste, broadly defined, and only about 1% are truly lower-caste. Ultimately, the minor moral panic over caste discrimination among a small minority of Americans is more a function of our nation’s current neuroses than the reality of caste in the United States.

But this does not mean that caste is not an important phenomenon to understand. In various ways, caste impacts the lives of the more than 1.4 billion citizens of India — 18% of humans alive today — whatever their religion. While the American system of racial slavery is four centuries old at most, India’s caste system was recorded by the Greek diplomat Megasthenes in 300 BC, and is likely far more ancient, perhaps as old as the Indus Valley Civilization more than 4,000 years ago. Indian caste has a deep pedigree as a social technology, and it illustrates the outer boundary of our species’ ability to organize itself into interconnected but discrete subcultures. And unlike many social institutions, caste is imprinted in the very genes of Indians today.

Of Memes and Genes

Beginning about twenty-five years ago, geneticists finally began to look at the variation within the Indian subcontinent, and were shocked by what they found. In small villages in India, Dalits, formerly called “outcastes,” were as genetically distinct from their Brahmin neighbors as Swedes were from Sicilians. In fact, a Brahmin from the far southern state of Tamil Nadu was genetically closer to a Brahmin from the northern state of Punjab then they were to their fellow non-Brahmin Tamils. Dalits from the north were similar to Dalits from the south, while the three upper castes, Brahmins, Kshatriyas and Vaishyas, tended to cluster together against the Sudras.

Some scholars, like Nicholas Dirks, the former chancellor of UC Berkeley, argued for the mobility and dynamism of the caste system in their scholarship. But the genetic evidence seemed to indicate a level of social stratification that echoes through millennia. Across the subcontinent, Dalit castes engaged in menial and unsanitary labor and therefore were considered ritually impure. Meanwhile, Brahmins were the custodians of the Hindu Vedic tradition that ultimately bound the Indic cultures together with other Indo-European traditions, like that of the ancient Iranians or Greeks. Other castes also had their occupations: Kshatriyas were the warriors, while Vaishyas were merchants and other economically productive occupations.

Brahmins, Kshatriyas, and Vaishyas were traditionally the three “twice-born” castes, allowing them to study the Hindu scriptures after an initiatory ritual. The majority of the population were Sudras (or Shudras), India’s peasant and laboring majority. Shudras could not study the scriptures, and might be excluded from some temples and festivals, but they were integrated into the Hindu fold, and served by Brahmin priests. A traditional ethnohistory posits that elite Brahmin priests and Kshatriya rulers combined with Vaishya commoners formed the core of the early Aryan society in the subcontinent, with Shudras integrated into their tribes as indigenous subalterns. Outcastes were tribes and other assorted latecomers who were assimilated at the very bottom of the social system, performing the most degrading and impure tasks.

The caste system as a layered varna system with five classes and numerous integrated jati communities.
Razib Khan

This was the theory. Reality is always more complex. In India, the caste system combines two different social categories: varna and jati. Varna derives from the tripartite Indo-European system, in India represented by Brahmins, Kshatriyas, and Vaishyas. It literally translates as “color”, white for Brahmin purity, red for Kshatriya power, and yellow for Vaishya fertility. But India also has Shudras, black for labor. In contrast to the simplicity of varna, with its four classes, jati is fractured into thousands of localized communities. If varna is connected to the deep history of Indo-Aryans and is freighted with religious significance, jati is the concrete expression of Indian communitarianism in local places and times.

QotD: What we mean by the term “indigenous”

Filed under: Africa, Americas, Asia, Europe, History, India, Quotations, Science — Tags: , , , , , , , , , , — Nicholas @ 01:00

Well, if by indigenous we mean “the minimally admixed descendants of the first humans to live in a place”, we can be pretty confident about the Polynesians, the Icelanders, and the British in Bermuda. Beyond that, probably also those Amazonian populations with substantial Population Y ancestry and some of the speakers of non-Pama–Nyungan languages in northern Australia? The African pygmies and Khoisan speakers of click languages who escaped the Bantu expansion have a decent claim, but given the wealth of hominin fossils in Africa it seems pretty likely that most of their ancestors displaced someone. Certainly many North American groups did; the “skraelings” whom the Norse encountered in Newfoundland were probably the Dorset, who within a few hundred years were completely replaced by the Thule culture, ancestors of the modern Inuit. (Ironically, the people who drove the Norse out of Vinland might have been better off if they’d stayed; they could hardly have done worse.)

But of course this is pedantic nitpicking (my speciality), because legally “indigenous” means “descended from the people who were there before European colonialism”: the Inuit are “indigenous” because they were in Newfoundland and Greenland when Martin Frobisher showed up, regardless of the fact that they had only arrived from western Alaska about five hundred years earlier. Indigineity in practice is not a factual claim, it’s a political one, based on the idea that the movements, mixtures, and wholesale destructions of populations since 1500 are qualitatively different from earlier ones. But the only real difference I see, aside from them being more recent, is that they were often less thorough — in large part because they were more recent. In many parts of the world, the Europeans were encountering dense populations of agriculturalists who had already moved into the area, killed or displaced the hunter-gatherers who lived there, and settled down. For instance, there’s a lot of French and English spoken in sub-Saharan Africa, but it hasn’t displaced the Bantu languages like they displaced the click languages. Spanish has made greater inroads in Central and South America, but there’s still a lot more pre-colonial ancestry among people there than there is pre-Bantu ancestry in Africa. I think these analogies work, because as far as I can tell the colonization of North America and Australia look a lot like the Early European Farmer and Bantu expansions (technologically advanced agriculturalists show up and replace pretty much everyone, genetically and culturally), while the colonization of Central and South America looks more like the Yamnaya expansion into Europe (a bunch of men show up, introduce exciting new disease that destabilizes an agricultural civilization,1 replace the language and heavily influence the culture, but mix with rather than replacing the population).

Some people argue that it makes sense to talk about European colonialism differently than other population expansions because it’s had a unique role in shaping the modern world, but I think that’s historically myopic: the spread of agriculture did far more to change people’s lives, the Yamnaya expansion also had a tremendous impact on the world, and I could go on. And of course the way it’s deployed is pretty disingenuous, because the trendier land acknowledgements become, the more the people being acknowledged start saying, “Well, are you going to give it back?” (Of course they’re not going to give it back.) It comes off as a sort of woke white man’s burden: of course they showed up and killed the people who were already here and took their stuff, but we’re civilized and ought to know better, so only we are blameworthy.

More reasonable, I think, is the idea that (some of) the direct descendants of the winners and losers in this episode of the Way Of The World are still around and still in positions of advantage or disadvantage based on its outcome, so it’s more salient than previous episodes. Even if, a thousand years ago, your ancestors rolled in and destroyed someone else’s culture, it still sucks when some third group shows up and destroys yours. It’s just, you know, a little embarrassing when you’ve spent a few decades couching your post-colonial objections in terms of how mean and unfair it is to do that, and then the aDNA reveals your own population’s past …

Reich gets into this a bit in his chapter on India, where it’s pretty clear that the archaeological and genetic evidence all point to a bunch of Indo-Iranian bros with steppe ancestry and chariots rolling down into the Indus Valley and replacing basically all the Y chromosomes, but his Indian coauthors (who had provided the DNA samples) didn’t want to imply that substantial Indian ancestry came from outside India. (In the end, the paper got written without speculating on the origins of the Ancestral North Indians and merely describing their similarity to other groups with steppe ancestry.) Being autochthonous is clearly very important to many peoples’ identities, in a way that’s hard to wrap your head around as an American or northern European: Americans because blah blah nation of immigrants blah, obviously, but a lot of northern European stories about ethnogenesis (particularly from the French, Germans, and English) draw heavily on historical Germanic tribal migrations and the notion of descent (at least in part) from invading conquerors.

One underlying theme in the book — a theme Reich doesn’t explicitly draw out but which really intrigued me — is the tension between theory and data in our attempts to understand the world. You wrote above about those two paradigms to explain the spread of prehistoric cultures, which the lingo terms “migrationism” (people moved into their neighbors’ territory and took their pots with them) and “diffusionism”2 (people had cool pots and their neighbors copied them), and which archaeologists tended to adopt for reasons that had as much to do with politics and ideology as with the actual facts on (in!) the ground. And you’re right that in most cases where we now have aDNA evidence, the migrationists were correct — in the case of the Yamnaya, most modern migrationists didn’t go nearly far enough — but it’s worth pointing out that all those 19th century Germans who got so excited about looking for the Proto-Indo-European Urheimat were just as driven by ideology as the 21st century Germans who resigned as Reich’s coauthors on a 2015 article where they thought the conclusions were too close to the work of Gustaf Kossinna (d. 1931), whose ideas had been popular under the Nazis. (They didn’t think the conclusions were incorrect, mind you, they just didn’t want to be associated with them.) But on the other hand, you need a theory to tell you where and how to look; you can’t just be a phenomenological petri dish waiting for some datum to hit you. This is sort of the Popperian story of How Science Works, but it’s more complex because there are all kinds of extra-scientific implications to the theories we construct around our data.

The migrationist/diffusionist debate is mostly settled, but it turns out there’s another issue looming where data and theory collide: the more we know about the structure and history of various populations, the more we realize that we should expect to find what Reich calls “substantial average biological differences” between them. A lot of these differences aren’t going to be along axes we think have moral implications — “people with Northern European ancestry are more likely to be tall” or “people with Tibetan ancestry tend to be better at functioning at high altitudes” isn’t a fraught claim. (Plus, it’s not clear that all the differences we’ve observed so far are because one population is uniformly better: many could be explained by greater variation within one population. Are people with West African ancestry overrepresented among sprinters because they’re 0.8 SD better at sprinting, or because the 33% higher genetic diversity among West Africans compared to people without recent African ancestry means you get more really good sprinters and more really bad ones?) But there are a lot of behavioral and cognitive traits where genes obviously play some role, but which we also feel are morally weighty — intelligence is the most obvious example, but impulsivity and the ability to delay gratification are also heritable, and there are probably lots of others. Reich is adorably optimistic about all this, especially for a book written in 2018, and suggests that it shouldn’t be a problem to simultaneously (1) recognize that members of Population A are statistically likely to be better at some thing than members of Population B, and (2) treat members of all populations as individuals and give them opportunities to succeed in all walks of life to the best of their personal abilities, whether the result of genetic predisposition or hard work. And I agree that this is a laudable goal! But for inspiration on how our society can both recognize average differences and enable individual achievement, Reich suggests we turn to our successes in doing this for … sex differences! Womp womp.

    1. aDNA works for microbes too, and it looks like Y. pestis, the plague, came from the steppe with the Yamnaya. It didn’t yet have the mutation that causes buboes, but the pneumonic version of the disease is plenty deadly, especially to the Early European Farmers who didn’t have any protection against it. In fact, as far as we can tell, in all of human history there have only been four unique introductions of plague from its natural reservoirs in the Central Asian steppe: the one that came with or slightly preceded the Yamnaya expansion around 5kya, the Plague of Justinian, the Black Death, and an outbreak that began in Yunnan in 1855. The waves of plague that wracked Europe throughout the medieval and early modern periods were just new pulses of the strain that had caused Black Death. Johannes Krause gets into this a bit in his A Short History of Humanity, which I didn’t actually care for because his treatment of historic pandemics and migrations is so heavily inflected with Current Year concerns, but I haven’t found a better treatment in a book so it’s worth checking it out from the library if you’re interested.

    2. I cheated with that “pots not people” line in my earlier email; it usually gets (got?) trotted out not as a bit of epistemological modesty about what the archaeological record is capable of showing, but as a claim that the only movements involved were those of pots, not of people.

The fascinating world of trees

Filed under: Books, Environment — Tags: , , , — Nicholas @ 03:00

The latest book review from Mr. and Mrs. Psmith’s Bookshelf examines Tristan Gooley’s How to Read a Tree:

Okay, I admit it: I read this book because I wanted to know more about the trees in my yard.

I’m afraid that’s not how Tristan Gooley means it to be used. He’s an expert in what he terms “natural navigation“, which means finding your way wherever you’re going using the sun, moon, stars, weather, land, sea, plants and animals. He teaches classes in it. He tested Viking navigation methods in a small boat in the north Atlantic and wrote a scholarly paper about it. He traveled the desert with the Tuareg. He’s the only living person to have crossed the Atlantic solo in both a plane and a sailboat.1 Meanwhile, I consistently walk a block in the wrong direction when I come out of the subway. But I am interested in trees!

Do you think much about trees? Could you draw one from memory and come up with something besides a fat green lollipop? Can you describe a tree you walk past every day with something more than its species and “leaves turn a pretty color in the fall” or “had its whole middle chopped out because planting trees directly under power lines is a terrible idea”? (Or if you live somewhere urban enough to have buried power lines, “they really, really should have made sure all these ginkgos were male”.)2 My guess is that you can’t, because most of us couldn’t, but trees deserve some real thought. They are actually fabulously, unintuitively weird, and learning just a little bit about how they work will dramatically enhance your ability to understand why the world around you is the way it is. I don’t expect I’ll use a tree to find my way any time soon, but since reading the book I’ve started spotting things in my yard and my neighborhood that I’d never noticed before — and noticing things is halfway to understanding them. (Which is, of course, why you must not be permitted to notice that which you are not supposed to understand.)

The most fundamental insight here is that trees are not like animals. This sounds breathtakingly obvious (and indeed, when I shared this pearl of wisdom at the dinner table everyone laughed at me), but it’s hard to internalize. Our increasingly urbanized and domesticated lives have so impoverished our natural imaginary — the available stock of symbols, metaphors, and archetypes through which we understand the natural world — that we’re more or less limited to commensals and charismatic megafauna, and are therefore vaguely surprised when we encounter organisms that work differently.3 And trees really do work differently, in a wide variety of ways that make perfect sense when Gooley points them out.

What are these differences? Well, for one thing, where animals have their physical architecture written into their genes, trees — like all plants — have potential. Sure, they have general growth habits4 (you’d never mistake a willow for a maple), but compare two trees of the same species — even two genetically identical trees cloned from grafts or cuttings of the same parent — and you’ll find dramatic structural differences depending on how the individual tree grew. This isn’t true for animals: one lion might be smaller than another, or bear the scars of an old injury, but all lions have four legs with the same joint anatomy. A lion will never grow a new leg, drop an old one, or add new tendons to support a particularly overworked limb. Trees, on the other hand, do all of those and more, following general rules dictated by species but growing in response to the conditions they encounter. And because only the top of the tree continues to grow up — a branch five feet off the ground will still be five feet off the ground in a decade, though quite a lot thicker — you can read a tree’s whole history in its structure. As with looking at a genome, looking at a tree is a way of looking into the past.

Trees seek the light. Just down the street, my neighbor’s entire front yard is shaded by three enormous oak trees planted in a rough triangle and each arching gently away from the others (with a surprising similarity to the Air Force Memorial) as they try to escape each others’ shade. A few blocks away is a survivor of a similar situation, an old pine tree that’s branchless most of the way up its trunk so you can really see the alarming 15° lean with which it grew. Some long-gone giant cast the shade that sculpted this tree into its present funny shape, and if we were in the woods we might be able to see its stump — Gooley encourages the reader to greet a woodland stump by looking for the “footprint” of the missing tree in its surroundings — but I suspect this one was probably removed to make way for the foundation of the nearby house. (Given the apparent age of the pine and the house, its old neighbor probably met its end around the time the new streetcars turned this farming village on a railroad into a proper suburb.)

    1. The late Steve Fossett did it first, but since he holds about a billion other records it feels churlish to take this from Gooley.

    2. Only female gingkos drop those awful berries. There are entire all-male cultivars that make fabulous trees, and somehow, inexplicably, I spent every autumn of my childhood scraping horrible stinky mush off the bottoms of my shoes. Why.

    3. Also on this front, I recommend Merlin Sheldrake’s Entangled Life, which is exactly the sort of book about fungi you would expect someone named Merlin Sheldrake to write.

    4. In fact “tree” is really just a growth habit, evolved independently by thousands of unrelated species of plants, because trees are the crabs of the plant kingdom. [NR: Do read that thread, it’s quite amusing}

QotD: The obesity epidemic – a possible explanation

Filed under: Europe, Food, Health, History, Quotations — Tags: , , — Nicholas @ 01:00

Around 1970, the provision of food began to change and mightily. Boomers on their European tours — the first where a multitude could afford to travel — brought back cuisine to the New World and the abundance of food skyrocketed. Lower down on the socioeconomic scale fast food joints flooded neighborhoods and cities, and more and more cheap abundant food became available on every corner. Food corps gamed taste, making combinations irresistible to unsophisticated palates. The sugar manufacturers lobbied the FDA to make fat evil and carbs the food of choice. This has all been carefully documented by the New York Times, Harpers, [and] The Atlantic.

When I was growing up as a white supremacist, embedded in a neighborhood of white privilege, before all our communities were broken by forced immigration and vulture capitalism, we all, despite our relative wealth, ate the dullest food you can imagine. Simple, basic, and not a lot of it: fish sticks, hamburgers, a hunk of roast beef or lamb once in a while, canned vegetables, ice cream once a week, no pop, like ever. Mac and cheese. Spaghetti and meatballs. Roast chicken. That’s it. No Japanese, Chinese, French, Italian, fusion, Korean, Mexican. Out for dinner once a month. Maybe. Abstemious.

Add to this, the entire culture was Stoic. Suck it up buttercup was pretty much the solution to everything. Life was not fair. Your duty was to make it more fair. That’s was it. That is the entire ethic of white supremacy. You didn’t eat a lot because that was not good for a) you or b) your tribe on whom your survival was based. It meant you were cheating, taking more of scarce common resources. That was not OK. This wasn’t stated or even conscious, but it was hard-wired.

My ever so privileged tribe left the Levant around 30,000 years ago, hived off to the Mongol Steppes, then migrated north to Scandinavia, thence to northern Scotland, and then to Ireland. Pretty much starved all the way. For 30,000 years. Constant famines. Dying by the side of the trail, absorbed into the peat moss. Etc. Like that. Around 500 BC they moved to the Midlands and bred out those who were lactose intolerant. To this day I can live on milk and cheese and meat. Wild greens. Salt. Bread. Their diet.

Then, after 1500 years of breeding and starving in the Midlands, a strike of lightning: the Industrial Revolution leading inevitably to industrial food and abundance. For 300 years afterwards there wasn’t famine for us, but there was pioneering and starving to the point of having to eat squirrel and tree bark, wars and rationing. Then, for the first time, EVER, the massive cohort of boomers got into the job market, started to make money, fall in love, date and party, food got spectacular.

And everyone got fat. Genes taught to horde any excess bloomed into layers and layers of fat around every torso and butt. This is not a moral issue. This is genetic. For every “race” or ethnic grouping.

That’s it. The end. Period. Every one of us has this history embedded in our genetic structure, one way or another. It is a bitch. It means a constant war against your appetite and genetic history which is shrieking EAT EAT! It’s only the left that makes it into a crime. We are hardwired to see fat as dangerous to collective survival, and deep down, we know it’s just not healthy. Near everyone is fat and everyone worries about it.

My white privileged clan developed stoicism as the primary survival tool because it worked. For 30,000 years, it made it possible to survive anything. Today, white culture or rather, the dominant culture filled with people of every race and color still uses stoicism to succeed in every profession or activity. There is no escaping it.

QotD: Ancient DNA

Filed under: Americas, Asia, Books, Europe, Germany, History, Quotations, Science — Tags: , , , , , , , — Nicholas @ 01:00

… you know I’m always up for the humiliation of a dominant scientific paradigm. I especially like examples where that paradigm in its heyday replaced some much older and unfashionable view that we now know to be correct. It’s important to remind people that knowledge gets lost and buried in addition to being discovered.

The wonderful thing about ancient DNA is it gives us an extreme case of this. Basically, the first serious attempt at creating a scientific field of archaeology was done by 19th century Germans, and they looked around and dug some stuff up and concluded that the prehistoric world looked like the world of Conan the Barbarian: lots of “population replacement”, which is a euphemism for genocide and/or systematic slavery and mass rape. This 19th century German theory then became popular with some 20th century Germans who … uh … made the whole thing fall out of fashion by trying to put it into practice.

After those 20th century Germans were squashed, any ideas they were even tangentially associated with them became very unfashionable, and so there was a scientific revolution in archaeology! I’m sure this was just crazy timing, and actually everybody rationally sat down and reexamined the evidence and came to the conclusion that the disgraced theory was wrong (lol, lmao). Whatever the case, the new view was that the prehistoric world was incredibly peaceful, and everybody was peacefully trading with one another, and this thing where sometimes in a geological stratum one kind of house totally disappears and is replaced by a different kind of house is just that everybody decided at once that the other kind of house was cooler. The high-water mark of this revisionist paradigm even had people saying that the Vikings were mostly peaceful traders who sailed around respecting the non-aggression principle.

And then people started sequencing ancient DNA and … it turns out the bad old 19th century Germans were correct about pretty much everything. The genetic record is one of whole peoples frequently disappearing or, even more commonly, all of the men disappearing and other men carrying off the dead men’s female relatives. There are some exceptions to this, but by and large the old theory wins.

I used to have a Bulgarian coworker, and I asked him one day how things were going in Bulgaria. He replied in that morose Slavic way with a long, sad disquisition about how the Bulgarian race was in its twilight, their land was being colonized by others, their sons and daughters flying off to strange lands and mixing their blood with that of alien peoples. I felt awkward at this point, and stammered something about that being very sad, at which point he came alive and declared: “it is not sad, it is not special, it is the Way Of The World”. He then launched into a lecture about how the Bulgarians weren’t even native to their land, but had been bribed into moving there by the Byzantines who used them as a blunt instrument to exterminate some other unruly tribes that were causing them trouble. “History is all the same,” he concluded, “we invaded and took their land, and now others invade us and take our land, it is the Way Of The World.”

Even a cursory study of history shows that my Bulgarian friend was correct about the Way Of The World. There’s a kind of guilty white liberal who believes that European colonization and enslavement of others is some unique historical horror, a view that has now graduated into official state ideology in America. But that belief is just a weird sort of inverted narcissism. I guess pretending white people are uniquely bad at least makes them feel special, but white people are not special. Mass migration, colonization, population replacement, genocide, and slavery are the Way Of The World, and ancient DNA teaches us that it’s been the Way Of The World far longer than writing or agriculture have existed. It wasn’t civilization that corrupted us, there are no noble savages, “history is all the same”, an infinite history of blood.

Land acknowledgments always struck me as especially funny and stupid: like you really think those people were the first ones there? What about acknowledging the people that they stole it from? Sure enough one of the coolest parts of Reich’s book is his recounting the discovery that there were probably unrelated peoples in the Americas before the ancestors of the American Indians arrived here, and that a tiny remnant of them might even remain deep in Amazonia. So: what does it actually mean to be “indigenous”? Is anybody anywhere actually “indigenous”?

Speaking of Just-so stories, here’s “a simple story of fetish formation”

Filed under: Health, Technology — Tags: , , , , , — Nicholas @ 03:00

Scott Alexander ventures far from shore in this extended discussion of the notion that fetish research can help us understand more about artificial intelligence:

“Cologne BDSM 07” by CSD2006 is licensed under CC BY-SA 3.0 .

We try to explain AI alignment by analogy to human alignment. Evolution “created” humans. Its “goal” is for humans to spread their genes by (approximately) having as many children as possible. It couldn’t directly communicate that goal to humans – partly because it’s an abstract concept that can’t talk, and partly because for most of biological history it was working with lemurs and ape-men who couldn’t understand words anyway. Instead, it tried to give us instincts that align us with that goal. The most relevant instinct is sex: most humans want to have sex, an action that potentially results in pregnancy, childbearing, and genes being spread to the next generation. This alignment strategy succeeded well enough that humans populations remain high as of 2023.

We’ve talked before about a major failure: humans can invent contraception. Evolution’s main alignment strategy was totally unprepared for this. It made us interested in a certain type of genital friction, which was a good proxy for its goal in the ancestral environment. But once we became smarter, we got new out-of-training-distribution options available, and one of those was inventing contraception so that we could get the genital friction without the kids. This is a big part of why average-children-per-couple is declining from 8+ in eg pioneer times to ~1.5 in rich countries today, even though modern rich people have more child-rearing resources available than the pioneers.

Another major alignment failure is porn. Giving evolution a little more credit, it didn’t just make people want genital friction – if that had been the sole imperative, we would have died out as soon as someone inventing the dildo/fleshlight. People want genital friction associated with attractive people and certain emotions relating to complex relationships. But now we can take pictures of attractive people and write stories that evoke the complex emotions, while using a dildo/fleshlight/hand to provide the genital friction, and that does substitute for sex pretty well. There’s still debate over whether porn makes people less likely to go out and form real relationships, but it’s at least plausibly another factor in the rich-country fertility decline. At the very least it doesn’t scream “well-thought-out alignment strategy robust to training-vs-deployment differences”.

But these are boring examples. These are like 2015-level alignment concerns, from back when we thought the big problem was AIs seizing control of their reward centers or something. I think we might genuinely be able to avoid problems shaped like these. Unlike evolution, which had to work with lemurs, even weak GPT-level modern AIs are able to understand language and complicated concepts; we can tell them to want children instead of using genital friction as a proxy. 2023 alignment concerns are more about failed generalization – that is, about fetishes.

Evolution’s alignment problem isn’t just that humans have learned to satiate their libido in ways other than procreative sex. It’s that some humans’ libidos are fundamentally confused. For example, some men, instead of wanting to have sex with women, mostly want to spank them, or be whipped by them, or kiss their feet, or dress up in their clothes. None of these things are going to result in babies! You can’t trivially blame this on the shift from training to deployment (ie the environment of evolutionary adaptedness to the modern world) – women had feet in the ancestral environment too. This is a different kind of failure.

Here’s a simple story of fetish formation: evolution gave us genes that somehow unfold into a “sex drive” in the brain. But the genome doesn’t inherently contain concepts like “man”, “woman”, “penis”, or “vagina”. I’m not trying to make a woke point here: the genome is just a bunch of the nucleotides A, T, C, and G in various patterns, but concepts like “man” and “woman” are learned during childhood as patterns of neural connections. We assume that the nucleotides are a program telling the body to do useful things, but that has to be implemented through deterministic pathways of proteins and the brain’s neural connections are too complex to trivially influence that way (see here for more). The genome probably contains some nucleotides that are supposed to refer to the concepts “man” and “woman” once the brain gets them, but there’s are a lot of fallible proteins in between those two levels.

So the simple story of fetish formation is that the genome contains some message written in nucleotides saying “have procreative sex with adults of the opposite sex as you”, some galaxy-brained Rube Goldberg plan for translating that message into neural connections during childhood or adolescence, and sometimes the plan fails. Here are some zero-evidence just-so-story speculations for how various fetishes might form, more to give you an idea what I’m talking about than because I claim to have useful knowledge on this topic:

  • Foot fetish: On the somatosensory cortex, the area representing the feet is right next to the area representing the genitalia. If the genome includes an “address” for the genitalia, plus the instructions “have sexual urges towards this”, then getting the address slightly wrong will land you in the feet.

    • A reasonable next question would be “what’s on the other side of the genitalia, and do people also have fetishes about that one?” The answer is “the somatosensory cortex is a line with the genitalia at the far end, because God is merciful and didn’t want there to be a second thing like foot fetishes.”
    (source for cortex image)

  • Spanking: From the male point of view, penetrative PIV sex involves applying force to the bottom half of a woman, at rhythmic intervals, in a way that causes her very intense emotions and makes her make moan and scream. Spanking is exactly like this, and most kids encounter spanking at a very early age and sex only after they’re much older. If the evolutionary message is something like “find the concept that looks vaguely like this, then be into it”, spanking is the first concept like that most people will find; by the time they learn about actual sex, spanking might be a trapped prior.
  • Sadomasochism: Sex is painful for virgins, can be mildly painful even for some non-virgins, and when it’s pleasurable, it still looks a lot like pain (screams, intense emotions). Imagine you are a little boy/girl who stumbles in on your parents having sex. Your father is impaling the most sensitive part of your mother’s body, and your mother is moaning and squealing. A natural generalization might be “sex is the thing where a man causes a woman pain”.
  • Latex/rubber: Plausibly the evolutionary specification includes details about attractiveness. Attractive people (ie those you should be most interested in having babies with) should be young and healthy (characteristics associated with better pregnancy outcomes, especially in the high-risk ancestral environment). The simplest sign of youth and good health is smooth skin, so the evolutionary message might say something about preferring sex with smooth-skinned people. Latex is a superstimulus for smooth skin, and maybe if you see it at the right time, in the right situation, it can totally overwhelm the rest of the message.
  • Urine/scat: Procreative sex involves a sticky substance that comes out of the genitals, it doesn’t take much misgeneralization to get to other sticky substances that come out of the genitals or nearby regions.
  • Bondage/domination/submission: Okay, I admit I don’t have a good just-so explanation for this one. Maybe it’s more psychological – people who have been told that sex is shameful can only fully appreciate it if they feel like a victim who’s been forced into it (and so carries no guilt). And people who have been told they’re undesirable and nobody could ever really love them can only fully appreciate it if their partner is a victim who has no choice in the matter.
  • Furries: This has to be because of all the cute cartoon animals, right? But why do some people sexually imprint on them? I found this article on worshippers of the 1990s cartoon mouse Gadget helpful here. Gadget obviously has many desirable characteristics — she’s a very cute nerdy woman who sometimes ends up in damsel-in-distress situations. Maybe she is the most sexualized being that some six-year-old boys have encountered. When I watched Rescue Rangers as a six-year old, I could feel my brain trying to figure out whether to have a crush on her before deciding that no, it was too deep in latency stage. I assume most people who get their first crushes on Gadget or some other desirable cartoon character end up with their brains later generalize properly to “I like cute nerdy women in damsel-in-distress situations”, but a small minority misgeneralize to “nope, I’m only attracted to mice now, that’s where I’m going to go with this.”

Combine this with equivalent animal “fetishes” — things like beetles species where the females have red dots on their backs, and the males try to mate with anything that has a red dot — and you get a picture where evolution tries to communicate a lot of contingent features of sex in the hopes that one of them will stick, then tells you to be attracted to whatever is most associated with those features. At least for men, I think the features communicated in the genomic message are simple things like curves and thrusting and genitals and smooth skin, plus something that somehow picks out the concept of “woman” (except in 3% of the male population, where it picks out the concept of “men” instead, plus another 3% where it doesn’t pick out a sex at all).

Real procreative sex usually matches enough of features of the genomic message to be attractive to most people, but if the original triggers were associated with some contingent characteristics, the brain might misinterpret that as part of the target — for example, if it was a cartoon animal, the brain might think the target includes cartoon animals.

Other times, something that isn’t procreative sex matches the genomic message closely enough to be misinterpreted as the center of the target (eg getting whipped); usually procreative sex is somewhere in the target space, but maybe not the exact center, and a few people have such strong fetishes that procreative sex doesn’t register as erotic at all.

The process of forming the category “sexually attractive things” is just a special case of the process of forming categories at all. I discuss the formation of categories like “happiness” and “morality” in The Tails Coming Apart As Metaphor For Life. Society feeds us some labeled data about what is good or bad — for example, we might see someone commit murder on TV, and our parents tell us “No! That’s bad! Don’t do that!” (and the other TV characters hate and punish that character). Then we try to extrapolate such incidents to a broader moral system. If we’re philosophers, we might go further and try to formally describe that moral system, eg Kantianism, utilitarianism, divine command theory, natural law, etc. All of these correctly predict the training data (eg “murder is bad”) while having different opinions on out-of-distribution environments. Which one you choose is just a function of some kind of mysterious intellectual preference for how to generalize inherently ungeneralizeable things — what I previously described as “extrapolating a three-dimensional shape from its two-dimensional reinforcement-learning shadow”.

Fetishes are the same way. Here the evolutionary message provides semi-labeled data, giving people weird feelings when they see certain kinds of curvy, smooth-skinned people. Then people try to generalize that into an idea of what’s sexy. Usually their category is centered (in the sense that the category “bird” is centered around “sparrow” and not “ostrich”) around something close to procreative heterosexual sex. Other times they generalize in some very unexpected way, and are only attracted to cartoon mice. I think if we understood the laws of generalization, this would make sense. It would seem like a reasonable mistake that someone using Occam’s Razor and all the rest of the information-theoretic toolkit for generalization could make. But we don’t really understand those laws beyond faint outlines, so instead we’re reduced to YKINMKBYKIOK.

Britain’s troubling rise in hospital visits due to dog bites

Filed under: Britain, Health, History — Tags: , , — Nicholas @ 03:00

Ed West has a dog, but he admits he’s not really a “dog person”:

Dog breeds have different natures, something that would seem self-obviously true and yet which today the leading authorities in the British dog world seem to be in denial about, in particular when it comes to one of the unspoken trends of recent years – the huge increase in dog attacks.

This spike in dog-bites-man violence has led to a 50 per cent increase in hospital admissions for dog bites over ten years, the biggest rise being among children under the age of 4. Overall the number of fatalities has gone from an average of 3.3 in the 2000s to 10 last year, while dog attacks have risen recently from 16,000 in 2018 to 22,000 in 2022, and hospitalisations have almost doubled from 4,699 in 2007 to 8,819 in 2021/22.

The underlying story behind this escalation of violence is that much of it is the work of just one breed – the American Bully. And as we enter the summer holidays, the peak period for dog attacks, it’s worth pondering why the experts in the dog world are in such denial about the issue.

Public awareness of the American Bully problem has grown in recent months, spurred by some especially horrific attacks, as well as a widely-read article by legal academic and YouTuber Lawrence Newport. Lawrence looked at the data on dog attacks and observed that “a notable pattern emerges. In 2021, 2 of the 4 UK fatalities were from a breed known as the American Bully XL. In 2022, 6 out of 10 were American Bullies. In 2023, so far all fatalities appear to have been American Bullies.”

American Bullies, Newport explains, “are a breed resulting from modern mixes of the American Pitbull Terrier. They are known for very high muscle mass, biting power, and impressive strength, and come in several variations. Those that are bred for the greatest strength, weight and size are known as a part of the American Bully XL variety.”

Pitbulls are banned in Britain for a good reason, and in the US are responsible for “60–70% of dog fatalities“; yet under the Dangerous Dogs Act 1991 “the American Bully XL is currently permitted”.

What is surprising, Newport writes, is that “if you argue these dogs are dangerous, you will get a flood of comments from people … saying it’s the owner’s fault, not the dog’s. You might even be thinking this yourself, right now. But this is wrong. Whilst many Brits would contend that ‘Guns American Bully XL’s don’t kill people, people do’, the reality is different.

“Labradors retrieve. Pointers point. Cocker Spaniels will run through bushes, nose to the ground, looking as if they are tracking or hunting even when just playing – even when they have never been on a hunt of any kind. This is not controversial. Breeds have traits. We’ve bred them to have them.”

Pitbulls were created for bull-baiting, and when that was banned, they came to be bred to hunt down rats in a locked pen. “This required more speed, so they were interbred with terriers to make Pitbull Terriers. In addition to this, they began to be used for dog fighting: bred specifically to have aggression towards other dogs, and to be locked in a pit to fight (some are still used for this today). These were dogs likely kept in cages, away from humans, and bred for their capacity to earn money for their owners by winning fights. These were not dogs bred for loyalty to humans, these were dogs bred for indiscriminate, sustained and brutal violence contained within a pit.”

Recent discoveries in ancient DNA

Filed under: Africa, Americas, Asia, Books, Europe, History — Tags: , , , — Nicholas @ 04:00

The Psmiths, John and Jane, decided to jointly review a book by David Reich called Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past. This is Jane’s first contribution to an extended email thread between the Psmiths:

The problem with history is that there just isn’t enough of it. We’ve been around for, what, fifty thousand years? Conservatively.1 And we’ve barely written things down for a tenth of that. Archaeological excavation can take you a little farther back, but as the archaeologists always like to remind us, pots are not people. If you get lucky with a society that made things out of durable materials in a cold and/or dry environment (or you get very lucky with anaerobic preservation of organic materials, like in ice or bogs), maybe you can trace a material culture’s expansion and contraction across time and space. But that won’t tell you whether it’s a function of people moving and taking their stuff with them, or people’s neighbors going “ooh, using string to make patterns on your pots, that’s cool” and copying it. It certainly doesn’t tell you what their descendants were doing several thousand years later, potentially in an entirely different place and probably using an entirely different suite of technologies. Trying to understand what happened in the human past based on the historical and archaeological records is like walking into a room where a bomb has gone off and trying to reconstruct the locations of all the objects before the explosion. You can get some idea, but it’s all very broad strokes. And actually it’s worse than that, because it wasn’t just one explosion, it was lots, and we wouldn’t even know how many if we didn’t have a way of winding the clock back. But these days we do, and it’s ancient DNA.

Sometime between when my grandfather gave me a copy of Luca Cavalli-Sforza’s Genes, Peoples, and Languages for my birthday and when you and I decided to read Reich’s book together, two big things happened: humans got really, really good at sequencing and reading genomes, and Svante Pääbo’s lab in Leipzig got really, really good at extracting DNA from ancient bones. (How they developed their procedures is actually a really interesting story, which Pääbo retells in his book, but Reich — whose lab uses the same techniques on an industrial scale — gives a good, brief summary of how it works.) Together, these two advances unlocked … well, not quite everything about the deep past, but an absolutely enormous amount. Suddenly we can track the people, not just the pots, and the story is more complicated and fascinating than anything we might have expected. I’ve written elsewhere about some of the aDNA discoveries about human evolution (Neanderthal admixture, the Denisovans, etc.), but I’m even more excited about what ancient DNA reveals about our more recent past. Luckily, that’s what Reich spends most of the book on, with discussion of ancient ghost populations who now exist only in admixture and then chapters on the specific population genetic histories of Europe, India, North America, East Asia, and Africa, each of which contains some discoveries that would make (at least the more sensible) archaeologists and historical linguists go “well, duh” and others that are real surprises.

One of the “duh” stories is the final, conclusive identification of the people who brought horses, wagons, and Indo-European languages to Europe with the Yamnaya culture of the Pontic Steppe and their descendants. (David Anthony gives a very good overview of the archaeological case for this in The Wheel, the Horse, and Language, including some very cool experimental archaeology about horse teeth; you have my permission to skim the sections on pots.) My favorite surprising result, though, comes from a little farther north. People usually assume that Native Americans and East Asians share a common ancestor who split from the ancestors of Europeans and Africans before dividing into those two populations, but when Reich’s lab was trying to test the idea they found, to their surprise, that in places where Northern European genomes differ from Africans’, they are closer to Native Americans than to East Asians. Then, using a different set of statistical techniques, they found that Northern European populations were the product of mixture between two groups, one very similar to Sardinians (who are themselves almost-unmixed descendants of the first European farmers) and one that is most similar to Native Americans. They theorized a “ghost” population, which they called the “Ancient North Eurasians”, who had contributed DNA both to the population that would eventually cross the Bering land bridge and to the non-Early European Farmer ancestors of modern Northern Europeans. Several years later, another team sequenced the genome of a boy who died in Siberia 24kya and who was a perfect match for that theorized ghost ANE population.

But we’ve already established that I’m the prehistory nerd in this family; were you as jazzed as I was to read about the discovery of the Ancient North Eurasians?

    1. That’s the latest plausible date for the arrival of full “behavioral modernity” in Africa, though our genus goes back about two million years, tool use probably three million, and I think there’s a good case that Homo was meaningfully “us” by 500kya. (That’s “thousand years ago” in “I talk about deep history so much I need an acronym”, fyi.)

Ozempic versus the make-believe world of “Healthy at Every Size”

Filed under: Health, Media, USA — Tags: , , , , , — Nicholas @ 03:00

Poor Americans are being propagandized that being fat — even to the point of being unable to carry on ordinary tasks — is “perfectly healthy” at the same time that the glitterati, the wealthy, and the mediagenic are getting thinner thanks to diet, exercise, and (it’s an open secret) drugs and cosmetic surgery. Along comes an antidiabetic drug that was found to have an interesting off-schedule property:

If you, a commoner, encountered a feudal lord in the year 1200, the latter would likely be wearing fine armour, carrying a well-polished sword, and riding a horse. Upon seeing these visual cues, you would address him properly, lest he punish you for failing to show proper deference. But as the centuries passed, particularly in the years following the American and French revolutions, this notion of privilege faded; the rich might be a class apart, but at times they might be dressed much like you, even if their apparel was slightly better-made.

Today, however, the rich are separating themselves in perhaps the most obvious way of all: by perfecting their bodies, rather than what they put on them. The rich are fit and the poor are fat: reams of research confirms that the prevalence of obesity decreases as income increases. In the United States, where 41% of the entire population is obese — compared with 25% in the United Kingdom — it is a rare wealthy person who is morbidly overweight (blimp-sized Illinois governor J.B. Pritzker and portly former New Jersey governor Chris Christie are outliers). Increasingly, the rich in late middle age have come to resemble Jeff Bezos and Sarah Jessica Parker: ripped to shreds and almost certainly “enhanced” with various anti-ageing drugs and techniques, ranging from steroids and growth hormones to Botox injections and liposuction.

Into this mix comes semaglutide, an antidiabetic medication better known by its trade name Ozempic. Sold by pharmaceutical manufacturer Novo Nordisk, the drug, which reduces food intake by curbing appetite and slowing digestion, was approved by the US Food and Drug Administration to treat obesity in 2021. Since then, celebrities and fitness influencers have routinely shared before-and-after pics captioned with details of their courageous weight-loss journeys, which entailed jabbing themselves with a 1.5ml pen that contains a month’s worth of doses and costs roughly $900 without insurance.

Predictably, stories about Ozempic have proliferated in the tabloids and on social media. Some see the drug as a challenge to the celebrity movement that touts “fat acceptance”, and brought us the “slim-thick” era of curvy female superstars. They argue that Ozempic may work hand-in-hand with the return of the “heroin chic” look of the late Nineties. As interesting as it is to consider where these mixed messages might lead us — to a culture in which poor people are told it’s fabulous to be obese, while the rich get ever thinner and fitter — if this is a conspiracy, it’s not a new one. The rich have lusted after youth, beauty and fitness, in others and themselves, since time immemorial, always keeping the poor as downtrodden as possible while pacifying them with bromides about equality, liberty and fraternity. Ozempic, then, is not simply the key to thinness; those who pay for it are buying even more distance between themselves and the hoi polloi.

In short, this appears to be yet another sign that the elite are headed toward some sort of crude transhumanist utopia, complete with gene therapy and designer-baby selection. Some may scoff that this is science fiction, but this future looms: once they’re sufficiently fine-tuned, gene editing tools will likely eradicate heart disease, muscle wasting, neurodegenerative disorders, and other conditions in embryos that are still in utero — but their price will be nothing short of staggering. Similarly expensive gene therapies will enhance the overall performance of already-healthy humans, raising ethical questions about whether these procedures should “improve” a person or merely “fix” a condition. The rich, of course, will leave those debates to the philosophers and pay upfront for the best bodies that their considerable resources can buy. Already, news stories abound of billionaires pursuing immortality, with a few commentators trying to sanitise the pursuit by arguing that the research will somehow benefit even the least of us.

The clear drawbacks of depending too much on oral history

Filed under: Americas, Cancon, History, Science — Tags: , , , , , , — Nicholas @ 05:00

In The Line, Jen Gerson explains why you need to exercise caution when dealing with oral traditions:

Lac La Croix Indian Pony stallion – Mooke (Ojibway for – he comes forth), October 2008.

A BBC travel feature published several weeks ago had the hallmarks of a classic progressive narrative. It was the tale of the “endangered Ojibwe spirit horse; the breed, also known as the Lac La Croix Indian pony, is the only known indigenous horse breed in Canada.”

The spirit horse was reduced to near extinction by European settlers who treat these magical creatures, deemed “guides and teachers”, as a mere nuisance to be culled and eliminated in favour of more profitable animals like cattle, or so the telling goes. A native breed of a beloved animal struggling to survive in the face of voracious colonial settlers.

Someone call James Cameron.

Unless you know a little evolutionary history, that is. In which case, you will already be aware that this story is pure pseudoscientific hokum.

Look, no one likes to be disrespectful about sensitive matters where the legitimately oppressed and aggrieved claims of First Nations peoples are concerned. This is a nation that is struggling to come to terms with its own horrific colonial past. This process is taking on many forms: witness the applause granted to singer Jully Black, who recently amended the national anthem “our home on native land”. Or, perhaps, the calls by one NDP MP to combat residential school denialism by passing new laws on hate speech — which would make questioning certain narratives not only an act of heresy, but also a literal crime.

Listening to stories, and respecting lived experiences and oral histories Indigenous people at the core of Canadian history and identity has given a new credibility to the traditional knowledge of First Nations people in academia, media, and in society at large.

But the story of the Ojibwe spirit horse is a clear example of the limits of oral history.

The horses now roaming the plains of North America are not a native species. The horse did evolve on this continent before migrating to Asia and Europe. However, the North American breed is believed to have been extirpated about 10,000 years ago (or thereabouts) during a mass extinction event that wiped out almost all large land mammals.

There is some evidence that isolated pockets of a native horse breed may have survived in North America much later than this, but the horses roaming about today are descended from those that were brought from Europe after the 15th century.

Of course, science is always evolving, but the overwhelming bulk of genetic and archeological evidence to date supports this theory. The native North American horse is long, long gone. The bands of horses freely wandering the backcountry are not wild, but feral; they’re the product of escaped or abandoned horse stock of distant European origin.

Robert Heinlein’s “Crazy Years” have nothing on real headlines in 2022

Filed under: Books, Media, Politics, Science, USA — Tags: , , , , — Nicholas @ 05:00

Ed West on what he calls the “triumph of the blank slate” in western culture:

As a depressive conservative who always sneered at the new atheist movement, I’ve enjoyed a certain, almost masochistic smugness about the way the sharp decline in American religious practice has led to a proliferation of wacky beliefs. I told you so, I laugh, as our boat heads for the rocks and certain doom for all of us. And every month I read something else in the media which makes me think, with the best will in the world and a sincere belief in improving our lot, that country’s ruling class is losing its grip on reality.

To take one recent example, an article in the Atlantic recently made the case that separating sport by sex doesn’t make sense, because it “reinforces the idea that boys are inherently bigger, faster, and stronger than girls in a competitive setting — a notion that’s been challenged by scientists for years”.

The author stated that “though sex differences in sports show advantages for men, researchers today still don’t know how much of this to attribute to biological difference versus the lack of support provided to women athletes to reach their highest potential”.

Quoting an academic who claim “that sex differences aren’t really clear at all” the author reported of some studies showing that “the gap they did find between girls and boys was likely due to socialization, not biology”.

On a similar theme, a few weeks back the New York Times ran a piece arguing that “maternal instinct is a myth that men created”. In the essay, published in the world’s most influential newspaper, it was stated that “The notion that the selflessness and tenderness babies require is uniquely ingrained in the biology of women, ready to go at the flip of a switch, is a relatively modern — and pernicious — one. It was constructed over decades by men selling an image of what a mother should be, diverting our attention from what she actually is and calling it science.”

Even the most prestigious science magazines increasingly make claims about sex that a decade ago would have seemed wacky. Just recently, Scientific American stated that “Before the late 18th century, Western science recognized only one sex — the male — and considered the female body an inferior version of it. The shift historians call the ‘two-sex model’ served mainly to reinforce gender and racial divisions by tying social status to the body.”

If you find any of these beliefs strange, then you might need to “educate” yourself about “the science” because this is the direction of travel now. This kind of stuff is everywhere, growing in popularity in all areas, but all ultimately having the same common inheritance — the blank slate.

Yet what is strange is that such ideas are triumphant, even as the scientific evidence against them mounts up, with the expanding understanding of genetics and the role of inheritance. The tabula rasa should by all rights be dead, indeed it should have been killed twenty years ago with the publication of one of the most important books of the century so far, Steven Pinker’s The Blank Slate.

With its subtitle “the modern denial of human nature”, Pinker’s worked looked at the various ideas that had emerged out of academia and into wider society: that rape was not about sex, that hunter-gatherer societies were peaceful, that sex differences were learned, all of these beliefs having the common theme that humans are born with infinitely malleable minds and that that life outcomes are entirely shaped by society.

Pinker felt, quite reasonably, that many of these comforting beliefs were on the way out. Of the idea that differences in intelligence were entirely environmental, he wrote that “even in the 1970s the argument was tortuous, but by the 1980s it was desperate and today it is a historical curiosity”. And yet this historical curiosity continues to flourish, and 20 years after publication, the blank slate is stronger than ever. More so than in 2002, it’s taboo to discuss the genetic components of human intelligence or the biological factors involved in differing male and female behaviour. The ground has shifted – towards the blank slate.

Pinker is an optimistic Whiggish liberal who has since produced books looking at the decline of violence and making the case that things are getting better — that’s taken a wobble this decade, but I think he’ll be proven right, even if I think the new atheist-aligned cognitive psychologist has a slight blind spot about religion. In the Blank Slate he argued that worthy progressive goals should not rest on untrue scientific assumptions about human nature. When those ideas are proven false, the political argument will crumble too — and yet this hasn’t happened. Instead the taboos just grows stronger.

Sarah Hoyt on how Americans are mis-understanding the TV show Bridgerton

Filed under: Britain, History, Media, USA — Tags: , , , , — Nicholas @ 03:00

I don’t watch TV, so I haven’t seen the show myself, but apparently a lot of Blacks in the US are taking away the multi-racial casting of a parallel-universe TV show set in the Regency period as being a true representation of British history:

Anyway, all this came to a head with my watching the Bridgerton series. As other people know, it bothers the living daylights out of me to cast well-known historical figures as another race. Not because there can’t be decent actors of another race, but because I know there is a percentage of the population who takes fictional movies and shows as revealing “the truth”.

My mom, who is better educated (alas) than most American high school graduates is one of those. She will adapt her vision of the past according to some crazy movie she just watched. (The number of arguments I’ve had.)

For those who haven’t watched Bridgerton (bog standard regency romances, with gorgeous, if not period-accurate clothing) they cast a certain number of noblemen as black or indian or other “races” and the English Queen in Bridgerton is black.

The buried history in the mini-series (suggested and Heinleined in) is that black and white people coexisted in England side by side, until the king married a black Queen, and then suddenly mixed marriages were allowed.

This is obviously a fantastic parallel world history. Yes, there were black people in England in the regency. I’m sorry to tell you there were very few and 99% of them were slaves or servants brought by people who had lived in Africa.

There was no “black nobility” and no system of apartheid.

HOWEVER as we found out, American people absolutely believe this nonsense. They believe Queen Charlotte (mostly German, honestly) was “black” based on a very bad portrait and rumors of a Moorish ancestress. (Note this rumor was almost certainly political slander. Also that Moor at that time in the peninsula depending on whether in the South or the North might mean slim, small and tan, but did not mean AFRICAN.) Weirdly the best debunking I found was from Quora.

HOWEVER I also found endless pages of well-educated black-Americans celebrating Queen Charlotte for “Black history month”.

Let me also point out that both the Queen and her husband (Yes, mad King George) were ardent abolitionists and that did she have any legitimate hint of African blood ALL the opposition would have fixated on this, and the caricatures would have been next level. However this never happened. Queen Charlotte was and looked German, even if a portrait can imply “stereotypical” African features … As long as you remember that those features exist in a lot of other races, and that a lot of them are also Neanderthal.

Sure, if you go with the one drop theory, Queen Charlotte was black. So is everyone else. EVERYONE else, even those whose 23andme swears they’re pure Scandinavian. Because sometime in the last two thousand years all of us got an African ancestor, somewhere, on one of the many, many lines that fed into our family. (Note genealogy is also a lie to some extent, since it’s impossible to follow every single female (if you’re tracking the male. Vice versa otherwise) line that dropped into your family, and everyone who fed into every other of those lines.)

The problem is that it was the rats in the head of the American black producers of the series that led them to create this entire parallel universe which they THINK IS TRUE on the basis of “well the queen was black”. WITHOUT LOOKING.

And now those rats are reproducing everywhere, but most notably in black American heads, who now believe that “Well, the king married a black queen, so it must be true that the Americans rebelled to keep enslaving the black people”.

This is all not just arrant nonsense, but poisonous bullshit, and has no contact whatsoever with reality.

What can we do about it?

Correct it, ruthlessly, whenever we come across it. And keep pointing out that a queen who was blond and blue eyed was not in fact “black” unless everyone is. And that reading racial tea leaves is a pseudo-science, like phrenology.

I would very much appreciate if we could put this behind us so may family doesn’t keep getting asked “what is your racial background” by complete strangers. (And not just census takers, whom I like to answer with “human”.)

Look, in the end, the darkest African and the lightest Scandinavian have more in common with each other than not. To pretend otherwise is arrant nonsense.

Yes, our far-distant ancestors developed racism as a necessary survival tool (along with the uncanny valley discomfort) because you could fall into the hands of another hominin band and become “food”. (The chimps are less discriminating and will also eat babies of their own band.)

We are now past that, and I would like it not to return. Yes, there are physical characteristics that go with certain character traits, but it’s harder to track than you think, and they’re often things that have nothing to do with race, let alone racial stereotypes.

We all have one drop of slaves and enslaved, or saints, sinners, murderers, murder victims, kings and peasants, ascetics and whores. And we all have all the inclinations of all of mankind in varying degrees.
It’s what you make of it and with it that determines whether you can wear “human” as a crown, or in fact get cast out of the human race for shoving in line.

It’s time to stop with the nonsense.

QotD: Chaos, the ancient enemy

Filed under: Europe, History, Humour, Quotations — Tags: , , , — Nicholas @ 01:00

No, not that one. Though perhaps that one, or a more concrete incarnation of it. Though evil seems cohesive and organized, it is often either about to bring about the oldest enemy of mankind, perhaps the oldest enemy of life or perhaps just that enemy with a mask on, dancing forever formlessly in the void.

I was probably one of the few people not at all surprised that Jordan Peterson’s seminal work was subtitled “An antidote to chaos”. Because of course that is our ancient enemy, the enemy of everything that lives down to the smallest organized cell.

Perhaps it is my Greek ancestry (in culture, via the Romans, if nothing else. I mean 23 and me has opinions, but they revise my genetic makeup so often I’m not betting on anything. Also, frankly, they base it on today’s populations, so that if say every person in an extended family left Greece to colonize Iberia, today I’d show only Iberian genetics. [Spoiler: I don’t. Europeans are far more mixed up than they dream of in their philosophies.]) that makes me see Chaos as a vast force waiting in the darkness before and around this brief bit of light that is Earth and humanity, ready to devour us all.

I can’t be the only one impressed by this image, as I’ve run across echoes of it in countless stories both science fiction and fantasy. If you’re reading the kind of story that tries to scrute the ultimate inscrutable and unscrew the parts of the mental universe of humanity to take a metaphorical look under the hood, sooner or later you come across a scene where the main characters get to the end of it all and face howling chaos and darkness. Only it usually doesn’t even howl, nor is it dark. It’s just nothing. Which is the ultimate face and vision of chaos. And most of us know it. Perhaps writers, most of all.

I have a complex relation with chaos, in that part of me seems to be permanently submerged in it. Some of this is the culture in which I was brought up. You know, the Portuguese might have crime, but no one can accuse them of having organized crime. Or indeed organized much of anything.

It’s not just the disease of “late industrializing culture”. There’s something more at work. For one, the Portuguese pride themselves on it. They routinely contrast the British habit of queuing for everything to the Portuguese habit of queuing for nothing (And you haven’t lived till you see a communion scrum with the little old ladies having their elbows at the level of young men’s crotches) by describing the way Portuguese do not queue as “All in a pile and may G-d help us”.
