Ancient DNA Unravels Europe’s Genetic Diversity“Ancient DNA recovered from a time series of skeletons in Germany spanning 4,000 years of prehistory has been used to reconstruct the first detailed genetic history of modern-day Europeans. The study, published today in ‘Science’, reveals dramatic population changes with waves of prehistoric migration, not only from the accepted path via the Near East, but also from Western and Eastern Europe.” – orig. research article: Ancient DNA Reveals Key Stages in the Formation of Central European Mitochondrial Genetic Diversity. from dienekes: “Anyone adhering to a ‘pots not people’ paradigm will find difficult to explain the sharp discontinuities found in the genetic record.” – and here’s national geographic’s take on the story – my head’s dizzy from all the spin!: “So, just like parts of Europe today are melting pots from different living cultures across the world, Europe is also a melting pot of genetic lineages from different prehistoric cultures that lived there at different periods of time.” – see also: Stone Age farmers, hunters kept their distance.

Genes Suggest European Women at Root of Ashkenazi Family Tree“The women who founded the Ashkenazi Jewish community of Europe were not from the Near East, as previously supposed, and reinforces the idea that many Jewish communities outside Israel were founded by single men who married and converted local women.” – see dienekes and greg cochran.

Child Behaviour: Not In Their Genes?“Using a powerful approach called GCTA, King’s College London researchers Maciej Trzaskowski and colleagues found no evidence that genetics can explain differences in children’s behavioural and conduct difficulties.” – @neuroskeptic.

“Were the First Artists Mostly Women?“Three-quarters of handprints in ancient cave art were left by women, study finds.” — afaics, there’s no reason to conclude that the individuals who spray painted outlines of their hands (any idiot can do that — I could do that!) were the same individuals who painted the horses and lions, etc. duh. anyway, here’s the interesting bit from the article: “[T]he hands in the caves were much more sexually dimorphic than modern hands, meaning that there was little overlap in the various hand measurements. ‘They fall at the extreme ends, and even beyond the extreme ends,’ Snow said. ‘Twenty thousand years ago, men were men and women were women.’”

Glass always half-empty? Your genes may be to blame“UBC researcher finds some people are genetically predisposed to seeing things in a negative light. Further research is also planned to explore the gene variant’s occurrence across different ethnic groups. While it is believed more than half of Caucasians have ADRA2b, some studies suggest it is much less prominent in other ethnicities….”

Whites More Prone to Certain Heart Condition Than Other Ethnic Groups“In a study to be published online October 8 and in the November 12 issue of ‘Circulation’, researchers discovered that self-described non-Hispanic whites are more likely to develop atrial fibrillation than people from other race or ethnic groups. ‘We found that consistently, every other race had a statistically significant lower risk of atrial fibrillation compared to whites…. So this suggests that white race is itself a risk factor for atrial fibrillation.’” – h/t mr. mangan, esq!

Changes in women’s attractiveness perception of masculine men’s dances across the ovulatory cycle: Preliminary data“Women’s preferences for putative cues of genetic quality in men’s voices, faces, bodies, and behavioral displays are stronger during the fertile phase of the ovulatory cycle. Here we show that ovulatory cycle-related changes in women’s attractiveness perceptions of male features are also found with dance movements, especially those perceived as highly masculine.”

Similar chimpanzees form friendships“‘We found that, especially among unrelated friends, the most sociable and bold individuals preferred the company of other highly sociable and bold individuals, whereas shy and less sociable ones spent time with other similarly aloof and shy chimpanzees,’ says the researcher. The researchers argue that such a strong preference for self-like individuals is probably adaptive, because frequent cooperation becomes more reliable when both partners have similar behavioural tendencies and emotional states. This finding strongly resembles the known ‘similarity effect’ in humans: We tend to make friends with people who are equally extraverted, friendly and bold as ourselves.” — same in some birds, too, remember?

The Anglosphere miracle – by daniel hannan – “As for the idea that the individual should be as free as possible from state coercion, this is regarded as the ultimate Anglophone fetish. Whenever the E.U. extends its jurisdiction into a new field—decreeing what vitamins we can buy, how much capital banks must hold, what hours we may work, how herbal remedies are to be regulated—I ask what specific problem the new rules are needed to solve. The response is always the same: ‘But the old system was unregulated!’ The idea that absence of regulation might be a natural state of affairs is seen as preposterous.”

Appearances can conceal as much as they reveal.” – great #longread about isaac newton.

Preventing penile fractures and Peyronie’s disease – DON’T try this at home!: “In some Middle East regions, men engage in a practice known as *taqaandan* (‘to click’ in Kurdish), explains Dr. Javaad Zargooshi, urology professor at Kermanshah University of Medical Sciences in Iran. It’s a painless process, similar to knuckle-cracking, in which the top half of an erect penis is bent forcefully while the rest of the shaft is held stationary. Usually this produces only a loss of erection and a satisfying popping noise, says Zargooshi, who published a report on the phenomenon in December in the Journal of Sexual Medicine. Other times, it will fracture the penis.” – wait. what? – via ed west!

today, some classics (and soon-to-be classics?):

Latitude, elevation and the tempo of molecular evolution in mammals“[B]ecause climatic variables change with latitude and elevation in a similar manner, our results suggest that climate has influenced the tempo of genetic change in mammals…. These findings provide new insights into microevolution that are likely to have important implications for understanding global patterns of biodiversity and diversification.”

An Asian perspective on early human dispersal from Africa“Asia might not have been the passive recipient of whatever migrated out of Africa but might have been a major donor to speciation events, as well as dispersals back into Africa. Such two-way traffic is well documented for other mammals in the Pliocene and Early Pleistocene, such as Equus and bovids, with more taxa migrating into than out of Africa. There is no reason why hominin migrations were always from Africa into Asia, and movements in the opposite direction might also have occurred, as has been suggested for the Olduvai OH9 (refs 13, 58) and Daka specimens. We should even allow for the possibility that H. ergaster originated in Asia and perhaps explain its lack of an obvious east African ancestry as the result of immigration rather than a short (and undocumented) process of anagenetic (in situ) evolution (Dennell and Roebroeks 2005:1100-1101).” – see also: Did Early Humans First Arise in Asia, Not Africa?

Recent acceleration of human adaptive evolution“It is sometimes claimed that the pace of human evolution should have slowed as cultural adaptation supplanted genetic adaptation…. Cultural changes have reduced mortality rates, but variance in reproduction has continued to fuel genetic change. In our view, the rapid cultural evolution during the Late Pleistocene created vastly more opportunities for further genetic change, not fewer, as new avenues emerged for communication, social interactions, and creativity.” – hawks, wang, cochran, harpending & moyzis.

Human genetic diversity: Lewontin’s fallacy [opens pdf] – “In popular articles that play down the genetical differences among human populations, it is often stated that about 85% of the total genetical variation is due to individual differences within populations and only 15% to differences between populations or ethnic groups. … This conclusion, due to R.C. Lewontin in 1972, is unwarranted because the argument ignores the fact that most of the information that distinguishes populations is hidden in the correlation structure of the data and not simply in the variation of the individual factors.”

here are the results of the world values survey‘s civicness questions for france (2006) by region.

these data cover whites in france only. i’m pretty sure that doesn’t include north africans (berbers/arabs from algeria, for instance) because literally just a couple of the white respondents said they were muslims. so these data should really represent mostly ethnic french folks, with maybe some other europeans thrown in here and there. unlike in the post for spain, the samples sizes for all the (NUTS) regions of france were 50+. the pale yellow highlights indicate the region that had the highest score for a particular question (click on charts for LARGER views):

here’s a map of the average civicness scores for each region. note that, while the color scheme here is the same one i used on the map of spain, the scale is different. for instance, the least civic region in france (paris) is more civic than the most civic region in spain (catalonia):

the first thing to notice is that the civicness scores for ethnic french folks are lower than those of the anglo world across the board — often a lot lower. the french scores are lower than those of great britain (which i haven’t broken down by region/ethnicity yet — you’re next, g.b.!) — and, except for membership in a sport/recreation organization, lower than those for white americans. for example, in 2006, 17.10% of white americans said they were active members of a political party, while only 2.60% of whites in france said so.

wrt the flatlanders vs. mountain people theory, it looks to me as though the mountain dwellers of france, all of whom have a recent history of close matingthe auvergnats, those in alpine regions, and populations in the east, like in parts of lorraine — prove to be true to form in being less civic than the more lowland regions further to the west:

the most civic region of france — “paris east” (captain picardy, champagne-ardenne, and burgundy) — apart from being something of a lowland region, also appears to have been a part of early medieval austrasia. the population of this area is, therefore, likely, due to the “invention” of manorialism in this region, to have had one of the longest histories of outbreeding/nuclear family structures in nw europe. (however, as charles donahue has shown, during the medieval period, the people of this region practiced arranged marriages much more often than in england during the same time period, so marriage wasn’t quite as “free” historically in this region as amongst the english.)

the least civic region of france is paris — but, of course, paris is a thoroughly multi-cultural city, and so its residents probably suffer from putnam’s lack of trust [opens pdf] that arises naturally in diverse societies.

the next least civic region of france is nord-pas-de-calais which is also multi-cultural in its own way being comprised historically of both french and flemish speakers. (there are also, apparently, a lot of other europeans, and more recent immigrants from africa/latin america, living in the region.) again, diversity does not normally make for civic societies.

it might also be that the french flemings, like their distant neighbors/cousins(?) the frisians, had a longer history of inbreeding than other populations in northern france. i’m not sure about that since i don’t have any mating info on the french flemings — and i don’t know, either, what sort of territory they traditionally occupied (was it swampy like the frisians? and did they, therefore, miss out on manorialism like the frisians?).

oh — and remember how french canadians don’t seem to be very civic or trusting/charitable compared to anglo-canadians? well, isn’t it interesting that the same holds true for french people in france vs. anglos? and remember where in france most of the ancestors of french canadians hailed from? — the area outlined in red on this map? that is smack in the middle of a slightly upland, not-so-very civic region in france today: “paris west” at 8.93%.

previously: civic societies and civicness in the u.s. by race and the flatlanders vs. the mountain people and meanwhile, in france… and the auvergnat pashtuns and medieval manoralism and the hajnal line and “l’explication de l’idéologie” and more on medieval england and france and what’s up with french candians? and canadiens and canadiens again

ethnic enclaves are bad. if you want to keep people alive and prevent ethnic conflict, that is.

a couple of real world examples…

first, guatemala. in “Spatial and Temporal Patterns in Civil Violence: Guatemala 1977-1986,” timothy gulden found, amongst other things, that [pg. 29]:

The amount of killing in a municipality was correlated with its ethnic mix….

“The distribution of ethnic population among municipalities was highly polarized and the distribution U-shaped, as suggested by the gray bars in the histogram presented as Figure 3.

“Thus, at both ends of this histogram, where one group or the other [ladinos vs. mayans] represented more than 90 percent of a local population, and also in the middle, where neither group was more than 75-percent dominant, killings of Mayans, the principal victims, were fewer.”

here’s the histogram:

more from gulden [pg. 34]:

The ethnic mix histogram showed the greatest number of killings in municipalities with predominantly Mayan populations, but fewer killings in the most heavily Mayan areas. This pattern might have been produced by an attempt to clear Mayans from mixed Mayan-Ladino areas but a disinclination to do the same, to attempt ‘ethnic cleansing,’ in the Mayan heartland. The ethnic mix histogram also showed a small rise in killings where Mayans were between 10 and 25 percent of the population. Minority populations of such proportions might somehow have threatened or annoyed a local Ladino majority without effectively restraining it. Members of the smallest Mayan populations were safer; they might typically have been individual servants or laborers, with or without families, well known to Ladino employers.”

re. switzerland and the former yugoslavia — from an article i posted about the other day, “Good Fences: The Importance of Setting Boundaries for Peaceful Coexistence”, the authors found that, in both switzerland and the former yugoslavia, there was the least amount of ethnic conflict in those areas where topographical and/or political boundaries clearly separated different linguistic, religious and/or ethnic groups, but where there were porous borders, there was more conflict. the former situation is more characteristic of switzerland on the whole, while the latter characterizes the former yugolavia, ergo more ethnic conflict in the former yugoslavia [pgs. 10-12]:

“Our work clarifies the ambiguities of mixed language and religion Swiss cantons by showing that in most cases the natural geography of the populations conspires to lead to a low level of violence, so that additional boundaries were not necessary; where they were needed, as in Graubunden, they were established. The highest calculated propensity to violence is between linguistic groups in the northern part of the canton of Bern, where historically unresolved real world tensions actually exist. Our analysis indicates that both administrative and natural barriers can play a significant role in mitigating conflict between religious and linguistic groups. Historical evidence suggests that for religious groups the boundaries in Switzerland were created to provide autonomy to a group with a shared identity and avoid conflict among multiple groups. Ongoing efforts to reduce tensions in Bern include introducing new political boundaries. The many political, social and economic factors that play roles in reducing violence build on a strong foundation of geographical borders.

diversity is strength … in killing games. =/
