First humans to leave Africa went to China, not Europe“The first humans to leave Africa decamped to far east Asia, not Europe. A trove of ancient teeth found in a cave in China adds evidence to the idea that humans reached the region thousands of years before they made it to Europe. The find suggests that modern humans reached China between 80,000 and 120,000 years ago. That challenges the widespread assumption that humans didn’t leave Africa until 60,000 years ago. It’s further evidence that Homo sapiens may have left Africa several times, says María Martinón-Torres of University College London. ‘It means we have to re-think different models of our dispersal.'” – and john hawks tweeted: “An 80kya modern human population in SE Asia w/Denisovan ancestry might help explain pattern of admixture in Philippines Mamanwa.”

Way Down South“I hear (tweets by Razib Khan, concerning Sankararaman’s talk at ASHG) that the Denisovans had substantially more genetic diversity than Neanderthals (determined mainly by the variety seen in admixed segments)….” – from greg cochran.

Basques are not simply a fusion of Iberian hunter-gatherers and early farmers“[T]he story told by the PCA is that Basques are the progeny of Bronze Age Iberians, who, unlike their Copper Age predecessors, experienced a pulse of steppe-related admixture from the east…. The key question now is who brought the steppe-related ancestry to Basque country. Were they Indo-Europeans or speakers of Proto-Basque?”

Sex‐specific demography and generalization of the Trivers–Willard theory – h/t owen jones! who tweeted: “Can mothers adaptively adjust offspring sex ratio? It’s complicated….”

The Great Migration and African-American genomic diversity“We find higher African ancestry in southern United States compared to the North and West. We show that relatedness patterns track north- and west-bound routes followed during the Great Migration, suggesting that admixture occurred predominantly in the South prior to the Civil War and that ancestry-biased migration is responsible for regional differences in ancestry. Rare genetic traits among African-Americans can therefore be shared over long geographic distances along the Great Migration routes, yet their distribution over short distances remains highly structured.”

Connectivity matrix predicts fluid intelligence“The enchanted loom is slowly giving up its secrets, of which it holds many. The patterns of brain activity that so many researchers have tracked with wonder are beginning to reveal a larger pattern: the possibility that each of us has a habitual pattern of brain activity which identifies us, and distinguishes us from others. So, dear reader, we are separated by the idiosyncratic rhythms of our brains, dancing to a different beat, visiting a different pattern of cortical locations, and no doubt coming to different conclusions…. The unexpected finding which I find startling is that individuals can be identified by their habitual brain patterns (not just on specific tasks) and those patterns of activity predict fluid intelligence on Raven’s Matrices at about r=0.5.” – from dr. james thompson.

Meta-analysis of associations between human brain volume and intelligence differences: How strong are they and what do they mean?“Positive associations between human intelligence and brain size have been suspected for more than 150 years…. Our results showed significant positive associations of brain volume and IQ (r = .24, R2 = .06) that generalize over age (children vs. adults), IQ domain (full-scale, performance, and verbal IQ), and sex…. We show that the strength of the positive association of brain volume and IQ has been overestimated in the literature, but remains robust even when accounting for different types of dissemination bias, although reported effects have been declining over time.”

Correlation not Causation: The Relationship between Personality Traits and Political Ideologies“Here we test the causal relationship between personality traits and political attitudes using a direction of causation structural model on a genetically informative sample. The results suggest that personality traits do not cause people to develop political attitudes; rather the correlation between the two is a function of an innate common underlying genetic factor.” – h/t robin hanson!

Generalised Anxiety Disorder – A Twin Study of Genetic Architecture, Genome-Wide Association and Differential Gene Expression“A heritability analysis of the same cohort also confirmed a significant genetic component with h2 of 0.42.” – h/t siberian fox! – and jayman tweeted: “I suspect anxiety is more common in some places than others. Perhaps due to genetic pacification.”

A Unified Crime Theory: The Evolutionary Taxonomy“Drawing on a variety of influences, we argue that many types of crime can be understood in the evolutionary context of human life history. Along these lines, we present a framework capable of explaining different patterns of criminal offending both at the individual level as well as the macro-level.” – from brian boutwell et al.

Resting heart rate and antisocial behavior: An updated systematic review and meta-analysis“Low resting heart rate was associated with higher levels of antisocial behavior…. Results were similar across behaviors, including aggression and violence.” – h/t anthony hoskin!

The association between childhood autistic traits and adolescent psychotic experiences is explained by general neuropsychiatric problems – from amir sariaslan et al. amir tweeted: “The ‘p factor’ explains assoc’s btwn childhood autistic traits and adolescent psychotic experiences.”

So what if grammars don’t help social mobility?“On the Today programme and the New Statesman website, a statistic was quoted showing that grammar schools have a smaller percentage of pupils on free school meals than comprehensives. There are probably many reasons for this, but most likely the largest factor involved is that intelligence is hereditary and social class correlates with IQ; in other words, middle-class kids tend on average to be more intelligent than working-class ones. You could make the system fairer by replacing grammar entrance exams (for which richer parents hire tutors to help their children pass) with straight-up IQ tests, but the number of poorer children would still be disproportionately low. In fact the more social mobility we have over the generations, as everyone seems to want, the more that social class will correlate with intelligence. Richard Herrnstein pointed this out more than four decades ago. Many years earlier, Michael Young warned about this very process in The Rise of the Meritocracy. Social mobility does have its downsides; that’s because intelligence is just another privilege you inherit from mummy and daddy.” – from ed west.

The economic value of Breaking Bad: How misbehavior in school pays off for some kids“Surprisingly, we find evidence that some non-cognitive skills that manifest as childhood misbehavior in the classroom (and are predictive of lower schooling attainment) are also predictive of higher earnings later in life.”

A social science without sacred values“We argue (1) that many social scientists are paranoid egalitarian meliorists; (2) that they are therefore very sensitive to threats to a sacred egalitarian narrative; (3) that this sensitivity may be excessive (at least in the domain of science) and may cause researchers to unfairly reject research that challenges egalitarianism; (4) that this may then lead to the marginalization of individuals who forward controversial theories and/or data; and (5) that these tendencies lead to bias in the social sciences.” – from the winegard bros.

The End of Indian Summer“At first, human rights commissions fought discrimination only in employment and housing, and there was strong resistance to prosecution of people simply for their ideas. This situation changed from the 1970s onward. Human rights took the place in society that formerly belonged to religion, and human rights advocates acquired the immunity from criticism that formerly belonged to the clergy. Discrimination was no longer wrong in certain cases and under certain circumstances. It became evil, and people who condoned it in any form and for any reason were likewise evil.” – from peter frost.

several people have compared the current migrant crisis in europe to the arrival of the barbarians in rome in the fourth century — for example, here’re steve sailer, peter frost, and historian tom holland. their concern — at least that of steve and peter — is the future of the west: will these migrants (help to) bring down modern western civilization just as the goths et al. did to rome? the question is not just an emotional or an irrational one — migration is one of the main driving forces of evolution (along with things like natural selection and genetic drift), since the movement of individuals from one population to another also means the movement of genes. and because all behavioral traits are heritable, the transference of genes via migration ought to be a matter of interest and importance to one and all. (that’s not to say that it should never be allowed, just that people(s) ought to pay it due attention.)

what i haven’t seen though are any comparisons to a more recent mass migratory event, one which also happened to feature germany, a major player in today’s migrant crisis. i suppose that’s because the whole subject is rather sensitive, but that’s no excuse for ignoring it — rather to the contrary! so, here goes…

in the late-1800s/early-1900s, at least a couple of million (i haven’t been able to find a precise number) eastern european jews migrated to and/or through germany. and how well did that work out for everybody?

from Unwelcome Strangers: East European Jews in Imperial Germany [pgs. 11-12]:

“In the last two years of the 1860s, a few thousand Russian Jews crossed into Prussia seeking relief from cholera epidemics and famines that were wreaking havoc in the western part of the Tsarist Empire. Desperately ill and malnourished, the refugees deluged their German coreligionists with pleas for economic assistance and medical attention. The latter responded by launching numerous ad hoc committees that collected funds throughout Germany and then funneled their receipts to Jewish communities along the frontier; these, in turn, provided relief to the needy. In time, the immediate crisis passed. Many of the Russian Jews remained in Prussia or traveled farther west, some as far as the New World. And the ad hoc committees, convinced that their mission had ended, folded their operations….

“Over the next half-century, the momentum of Jewish emigration from Russia steadily increased. During the 1870s perhaps 40,000 to 50,000 Jews migrated westward. After the pogroms of 1881, however, the trickle turned into a flood as tens of thousands abandoned their homes annually…. By the early twentieth century, over 100,000 such refugees emigrated each year, so that by 1914 at least two and a half million Russian Jews had settled in Western countries, including England, France, Canada, Argentina, and principally the United States.

“Concurrently, Jews from the Austro-Hungarian Empire and Rumania also were on the move. In the face of economic boycotts and rising unemployment at the end of the nineteenth century, Jews emigrated from the Polish sectors of the Hapsburg Empire. Rumanian Jews, too, made their way west after their country denied them citizenship and introduced blatantly anti-Jewish policies….”

(yes, eastern europeans are, on average, more xenophobic than most western european populations. and, judging by the above, they apparently have been for some time).

“…Between 1870 and the outbreak of World War I, over 400,000 Jews left their homes in the Galician, Bohemian, Moravian, Hungarian, and Rumanian lands to seek a new future in Western countries, while and even larger number migrated *within* the Austro-Hungarian Empire.

“Whereas anti-Semitism and impoverization provided the push to drive Jews *from* Eastern Europe, emigrants were also drawn *to* Western lands. They were lured by the promise of eonomic opportunity in the more industrialized West and the knowledge that their fellow Jews in England, France, Germany, and the New World countries enjoyed comparatively greater freedom and prosperity. The promise of toleration and opportunity, therefore, also attracted adventuresome Jews to seek their fortunes in new environments.

funnily enough, during at least some of this period, germany behaved more like macedonia or serbia today, shuffling the migrants onwards to the next country (making a ton of cash in the meantime, sounds like). ‘course the eastern european jews wanted to just migrate through germany, kind-of like the middle eastern/north african/african migrants of today don’t want to stay in macedonia or serbia or hungary [pgs. 13-14]:

“Germany had a vested economic interest in allowing Jewish refugees into the Reich. For Germany — and especially its shipping companies — hoped to benefit from the lucrative business of transporting Eastern Jews to England and America via the ports of Hamburg and Bremen. The sheer number of Jewish transmigrants embarking from German ports was staggering, exceeding 700,000 during the peak years between 1905 and 1914….

“The extent of German interest in encouraging Jewish transmigrant traffic is illustrated by some of the policies pursued by governments and shipping firms. For example, according to Prussian decrees in force between the 1890s and the outbreak of World War I, no Russian transmigrant was officially allowed into Germany without a proper pass, a ticket for passage out of the country, plus an additional sum of money. (Each person over ten years of age had to posses 400 mark, and children needed 100 mark.) Significantly, individuals holding tickets on German ships were exempted from this rule and permitted into the Reich even if they possessed less money. Perhaps the most revealing episode in the campaign to develop the transmigrant traffic occurred in 1893 when the eastern-most states of the Reich sealed their borders in response to cholera epidemics in Eastern Europe. Led by the Hamburg America Line, German shipping companies successfully lobbied for a reversal of this policy, arguing that Jewish transmigrants posed no health risk to the German populace. To further allay fears, shipping firms expended significant sums of money to erect special transport centers in key German cities and vast barrack areas in port cities; such facilities were designed to isolate Jewish travelers from the German populace and thereby eliminate objections to the temporary presence of these Jews on German soil.”

unfortunately, even though most of them didn’t even stay very long in germany, the ostjuden left a bad impression on the minds of germans. i couldn’t even tell you if any of the stereotypes were true or not, and if true by how much — and i really don’t want to get into a discussion about it here and now (although i strongly suspect that eastern european jews are, on average, more clannish than german jews, so there’s possibly that) — but even german jews at the time panicked a bit over the behaviors of their eastern cousins. from Brothers and Strangers: The East European Jew in German and German Jewish Consciousness, 1800-1923 [pgs. 33, 57]:

“German Jews undertook massive charitable work on behalf of the persecuted East European Jews at the same time that they sought the most efficacious means to prevent their mass settlement in Germany….

“Ultimately the difference between German Jews and Ostjuden, both in and out of Germany, was regarded as cultural in nature. Liberal German Jews viewed Eastern Jewish culture as ‘ghetto’ culture which by definition was backward and underdeveloped. The German historical experience had made it abundantly clear that Jewish modernization was conditional upon deghettoization, and this in turn left no room for *Kulturjuden* along the lines still maintained in Eastern Europe.

“This point of view was perfectly understandable. German Jews felt like Germans and their culture *was* German culture. By the beginning of the twentieth century they possessed almost nothing akin to the ‘Jewish’ culture that characterized life in the ghettos of Eastern Europe. The distance they felt, the dissociation from Ostjuden was, then, predicated upon both an objective and subjective reality.”

eastern european jews had a very different (bio-)culture to german jews and gentiles, one that, unfortunately, did not sit well with too many members of the mainstream culture. (the timing was bad, too. more on that below.) am i blaming jews for the holocaust? no. but i am warning — again — that in order to prevent future genocides, we need to understand previous ones, and that includes examining them with a biological/evolutionary eye. as i said previously:

“humans don’t *really* fight and kill neighboring populations or discriminate against subgroups within their nations — not to mention enslave one another — for any of the goofy ideological, religious, or ‘moral’ excuses that they give. those are mostly just after the fact rationalizations that they’ve come up with (no, really — the human brain is not to be trusted!). like other creatures, humans very often try to eliminate or dominate other groups *because they are in competition with them for resources* [pdf] — or, at least, *feel* that they are anyway, whatever the reality on the ground may be.”

bill hamilton pointed to the fourfold increase in the number of ashkenazi jews in eastern europe over the course of just the nineteenth century as a possible contributing factor to the holocaust. this would’ve represent an enormous change in the competition for resources between jews and gentiles in eastern europe. couple that already existing situation to the mass migration of a (bio-)culturally different population into/through germany at the turn of the century, and THEN the appalling economic conditions in germany after wwi and the stock market collapse — further feuling the competition for resources — and you have a recipe for an absolutely horrific biological disaster.

no, i’m not saying that such a scenario is guaranteed to happen again in the west with our new migrants. if there’s enough manna from heaven to go ’round, people probably won’t take it out on their neighbors. (there’s been no genocide of jews in the u.s. where times have generally been pretty good. always.) but i am saying that the powers that be ought to be MUCH more careful in shuffling peoples around willy-nilly. they’re playing a very dangerous game.
