Tracing Ancestry, Researchers Produce a Genetic Atlas of Human Mixing Events“Researchers have found genetic evidence for hundreds of examples of the large-scale mixing of human populations in the past 4,000 years.” – see also: A Genetic Atlas of Human Admixture History“We used this to produce an atlas of worldwide human admixture history, constructed by using genetic data alone and encompassing over 100 events occurring over the past 4000 years. We identified events whose dates and participants suggest they describe genetic impacts of the Mongol empire, Arab slave trade, Bantu expansion, first millennium CE migrations in Eastern Europe, and European colonialism, as well as unrecorded events, revealing admixture to be an almost universal force shaping human populations.” – see also: A genetic atlas of human admixture history. – see also from dienekes: Human admixture common in human history (Hellenthal et al. 2014).

Earliest footprints outside Africa discovered in Norfolk“Scientists have discovered the earliest evidence of human footprints outside of Africa, on the Norfolk Coast in the East of England. The footprints are more than 800,000 years old and were found on the shores of Happisburgh.”aaaand then they got washed away in the storms. (>_<)

Science discovers new ignorance about the past – good stuff from matt ridley.

Genetic origins of high-altitude adaptations in Tibetans“Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa. These genes were passed on to more recent migrants from lower elevations via population mixing, and then amplified by natural selection in the modern Tibetan gene pool, according to a new study.” – see also: Admixture facilitates genetic adaptations to high altitude in Tibet – see also: A novel mechanism for getting high – from greg cochran. – see also: Tibetan mastiffs equally adapted to high altitudes of Tibet.

Immediate replacement of fishing with dairying by the earliest farmers of the northeast Atlantic archipelagos [i.e. british isles] – “These new findings…unequivocally confirm rejection of marine resources by early farmers coinciding with the adoption of intensive dairy farming. This pattern of Neolithization contrasts markedly to that occurring contemporaneously in the Baltic, suggesting that geographically distinct ecological and cultural influences dictated the evolution of subsistence practices at this critical phase of European prehistory.”

The booms and busts of Neolithic Europe (and their potential impact on our DNA)“most of the interactions between the genetically Near Eastern-like Neolithic farmers and indigenous European hunter-gatherers, including mixing, in all likelihood took place on the peripheries of the farming societies. If so, then perhaps every time there was a bust, it was the relatively more admixed, or even more hunter-gatherer-like, farmer groups from the peripheries that took advantage of the situation and moved in to grab some land in the depopulated regions? In other words, this might have been the process which led to the well-documented reemergence of hunter-gatherer-derived ancestry in the heart of Europe after the early Neolithic.” – @eurogenes.

Genetic ancestry is associated with colorectal adenomas and adenocarcinomas in Latino populations“[I]ncreased African ancestry (or variants linked to it) contributes to the increased susceptibility of colorectal cancer in admixed Latin American population.” – h/t razib!

Black Death Left a Mark on Human Genome“Genetically, the Rroma are still quite similar to the northwestern Indians, even though they have lived side by side with the Romanians for a millennium, the team found. But there were 20 genes in the Rroma and the Romanians that had changes that were not seen in the Indians’ versions of those genes, Netea and his colleagues report online today in the Proceedings of the National Academy of Sciences. These genes ‘were positively selected for in the Romanians and in the gypsies but not in the Indians,’ Netea explains. ‘It’s a very strong signal.’”

Study demonstrates evolutionary ‘fitness’ not the most important determinant of success“By modelling populations over long timescales, the study showed that the ‘fitness’ of their traits was not the most important determinant of success. Instead, the most genetically available mutations dominated the changes in traits. The researchers found that the ‘fittest’ simply did not have time to be found, or to fix in the population over evolutionary timescales. The findings suggest that life on Earth today may not have come about by ‘survival of the fittest’, but rather by the ‘arrival of the frequent’.”

Burakumin, Paekchong, and Cagots“Human evolution is a logarithmic curve where most of the interesting changes have happened since the advent of farming and complex societies. *Homo sapiens* was not a culmination but rather a beginning…of gene-culture co-evolution. There are many ways to study this co-evolution, but one way is to look at the different evolutionary trajectories followed by castes and their host populations.” – from peter frost.

Geographic variation of human gut microbes tied to obesity“[P]eople living in northern latitudes have a greater proportion of the Firmicutes associated with obesity than do people living farther south, and a smaller proportion of Bacteroidetes.

Quick Post: L&V’s National IQs predict GMAT scores across 173 nations“We have shown that measures of national cognitive ability predict both GMAT scores and English proficiency scores independent of rates of English usage. GMAT and English proficiency scores seem to be indexes of National (g) by way of National IQ and National ACH.” – @human varieties.

Meritocracy doesn’t work. It’s in the Left’s interest to recognise this.“The Son Also Rises, a study of social mobility by Gregory Clark, will surprise and also alarm some people. He notes, by using surname patterns, that mobility is minimal in all societies where the data is available. Even, for example, in the Nordic paradise of Sweden. He says: ‘In all societies, what seems to matter is just who your parents are. At the extreme, we see in modern Sweden an extensive system of public education and social support. Yet underlying mobility rates are no higher in modern Sweden than in pre-industrial Sweden or medieval England.’ He also notes that even in revolutionary societies, such as in Communist China, people with aristocratic surnames also turn up at the top, showing that once again Darwin trumps Marx.” – from ed west. – see also: Everyone likes the idea of equal opportunity.

Males and females differ in specific brain structures“Reviewing over 20 years of neuroscience research into sex differences in brain structure, researchers have conducted the first meta-analysis of the evidence. The team performed a quantitative review of the brain imaging literature testing overall sex differences in total and regional brain volumes. They found that males on average have larger total brain volumes than women (by 8 to 13 percent). Looking more closely, the researchers found differences in volume between the sexes were located in several regions. These included parts of the limbic system, and the language system.”

Major sex differences in brain gene expression – from mr. mangan, esq. – also: How Can This Be? – from malcolm pollack.

How much do sex differences matter in sports?“Thanks in large part to testosterone, men are generally heavier and taller than women. They have longer limbs relative to their height, bigger hearts and lungs, less fat, denser bones, more oxygen-carrying red blood cells, heavier skeletons that support more muscle — 80 percent more in the upper body, on average, which is about the difference between male and female gorillas — and narrower hips that make for more efficient running and decrease the chance of injury. But since these differences generally don’t appear until puberty, boys’ and girls’ records in track tend to be identical before age 10. There’s scant biological reason to separate young boys and girls in competitions.” – from david epstein.

How the gender divide reaches into our nightmares“A study has found women are more likely to dream of interpersonal disputes, while men tend to face war, calamities and insect swarms alone.”

Be My Valentines: Is Monogamy Natural to Us?“It turns out that we aren’t monogamous or polygamous by nature. As everyone from poets to divorce attorneys can attest, we are by nature a profoundly confused species—somewhere in between.” – h/t robert ford!

Male infanticide leads to social monogamy in primates“The origin of social monogamy in primates is best explained by long lactation periods caused by altriciality, making primate infants particularly vulnerable to infanticidal males. We show that biparental care shortens relative lactation length, thereby reducing infanticide risk and increasing reproductive rates. These phylogenetic analyses support a key role for infanticide in the social evolution of primates, and potentially, humans.” – h/t heartiste!

23andMe Couples Correlated“For Valentine’s Day, we analyzed data from 15,298 real-world couples who had children together and found that people paired with others who were more like themselves than they were different.”

Ethnic diversity’s ‘inconvenient truths’“[W]hen the Vancouver Foundation recently conducted a massive survey of Metro Vancouver residents, researchers discovered most people in this West Coast city feel unusually high levels of loneliness and lack of friends…. The Vancouver Foundation survey of 3,800 diverse Metro residents confirmed Putnam’s results. It found one in four Metro residents feels alone more often than they would like, one-third consider Vancouver a difficult place to make friends, most don’t socialize with their neighbours, half don’t volunteer and most feel that, while diversity is generally a good thing, they prefer to be with members of their own ethnic group.” – h/t mike anissimov!

Rainforests in Far East shaped by humans for the last 11,000 years“New research shows that the tropical forests of South East Asia have been shaped by humans for the last 11,000 years.

How HBD Will Make you a Better Person“[F]orbidden knowledge does not result in genocide. The problem with this view is that genocide has been the norm throughout human history — that is, until very recently. On a historical timeline, our recent scientific knowledge of racial differences actually negatively correlates with the historic trend of genocide.” – @occam’s razor.

Y-chromosome “Adam” was not necessarily human“From the point of view of population genetics, there is absolutely no reason that the common ancestor of all human Y chromosomes must have existed in an individual that we would identify as ‘human’.”

Genomic variation in sharing between siblings“Visscher et al make really nice use of this slight variability in how much of the genome sibs share to learn about how much variation in height within a population is due to genetic variation. They use the fact that sibs who share slightly more of their genome (>0.5) should have more similar heights, than sibs who share less of their genomes (<0.5). This allows them to partition out how much of the resemblance between siblings is due to a shared environment, as opposed to shared genomes…. It also makes me wonder if sibs are actually unconsciously, weakly aware of these subtle genomic differences (through their similarity in a range of traits, including height etc). I could imagine doing a study where siblings (or others) are asked to assess how similar they are/feel, and then assessing whether this is weakly correlated with the fraction of the genome shared. I keep meaning to followup on this idea with some popgen theory to assess how this might play out in modifying kin-selection and altruism between sibs and other relatives." – from graham coop [this guy].

The Dark Enlightenment Hits Stage Two

La ciencia estúpida“La mayoría de los grandes científicos y filósofos no eran lo que diríamos tipos agradables. Tampoco eran políticamente correctos según el canon normal. Prácticamente ningún filósofo o científico anterior a la escuela de Frankfurt podría dar hoy una clase pública sin la amenaza de ser molestado por una turba emancipatoria. Hume, Darwin, Voltaire, Locke, Kant (no digamos ya Platón o Aristóteles) hoy no podrían ser contratados en la universidad de un país occidental.” – from eduardo zugasti.

Genome of longest-living cancer: 11,000-year-old living dog cancer reveals its origin, evolution“A cancer normally lives and dies with a person, however this is not the case with a sexually transmitted cancer in dogs. In a new study, researchers have described the genome and evolution of this cancer that has continued living within the dog population for the past 11,000 years.”

Why the masculine face? Genetic evidence reveals drawbacks of hyper-masculine features“[A]round half the variation in both male and female facial masculinity could be attributed to additive genetic variation…. The extensive genetic variation in masculinity makes more plausible the idea that choosing to mate with a masculine man can result in more attractive offspring. But the genes that made a male face more masculine did not make it more attractive. Worse, these same genes made female faces more masculine and thus less attractive. Families that make manly-looking sons tend also to make masculine-looking daughters.”

Casting Out The Devil“[C]onservatives generally think that liberals are misguided, and live in deep denial of obvious truths about human nature and the way the world actually works (as opposed to the way they think it *ought* to work), liberals view conservatives not just as misguided, but as *morally evil*.” – from malcolm pollack.

Social status influences Democrats’ — but not Republicans’ — support for reducing inequality“Low wealth Democrats supported legislation to reduce economic inequality significantly more than both high wealth Democrats and Republicans. ‘Whereas Republicans tended to sponsor legislation that supports economic inequality regardless of their wealth, wealth predicted sponsoring behavior for Democrats,” the researchers explained.’ Specifically, high wealth Democrats tended to sponsor fewer pieces of legislation that reduce economic inequality than did their lower wealth counterparts.”

Butterflies show origin of species as an evolutionary process, not a single event“The evolution of new species might not be as hard as it seems, even when diverging populations remain in contact and continue to produce offspring…. ‘We find that only a small fraction of the genome is markedly different between closely related species, but then much more of the genome — more than you’d expect — shows similar differences between more distantly related species…. That indicates that the genetic changes that are important for causing speciation are tightly clustered early in speciation, but not so later on in the process; the overall pattern of genome divergence starts slow and then skyrockets.’”

Mating advantage for rare males in wild guppy populations“Negative frequency-dependent selection (NFDS), a form of selection in which genotypes are favoured when they are rare, can potentially maintain such extensive polymorphism, but few experimental studies have confirmed its operation in nature…. Here we use highly replicated experimental manipulations of natural populations to show that males with rare colour patterns have higher reproductive fitness, demonstrating NFDS mediated by sexual selection. Rare males acquired more mates and sired more offspring compared to common males and, as previously reported, had higher rates of survival.” – h/t rob brooks!

Japanese north–south gradient in IQ predicts differences in stature, skin color, income, and homicide rate“In Japan, there is IQ gradient from north to south. Stature and average income cline is also from north to south. Homicide rates increase from north to south. Fertility rates and suicide rates decrease from north to south. Infant mortality is not correlated with latitude.”

Global patterns of sex-biased migrations in humans“We found that genetic differentiation between populations was higher for Y chromosome than for the mtDNA at global scales.

The rule-dependence model explains the commonalities between the Flynn effect and IQ gains via retesting“[W]e propose that Flynn effect gains are partly a function of the degree to which a test is dependent on rules or heuristics. This means that testees can become better at solving ‘rule-dependent’ problems over time in response to changing environments, which lead to the improvement of lower-order cognitive processes (such as implicit learning and aspects of working memory). These in turn lead to apparent IQ gains that are partially independent of general intelligence. We argue that the Flynn effect is directly analogous to IQ gains via retesting, noting that Raven’s Progressive Matrices is particularly sensitive to both the effects of retesting and the Flynn effect.” – from woodley and armstrong! (^_^) – see also dr. thompson.

Civilizations rise and fall on the quality of their soil“Great civilisations have fallen because they failed to prevent the degradation of the soils on which they were founded…. This is according to Professor Mary Scholes and Dr Bob Scholes who have published a paper in the journal Science, which describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.”

Bad reporting generates bad arguments“The Sunday Times gets 3.5 million readers a week. Anything mentioned in it has a chance of influencing public understanding and opinion in Britain. Last week they did a piece on Professor Robert Plomin’s recent book ‘G is for Genes’ which focuses on the genetic contribution to scholastic achievement. The newspaper’s coverage was misleading….” – of course. – from dr. james thompson.

Embryo Selection for Cognitive Enhancement“We find that embryo selection, on its own, may have significant impacts, but likely not drastic ones, over the next 50 years, though large effects could accumulate over multiple generations. However, there is a complementary technology, stem cell-derived gametes, which has been making rapid progress and which could amplify the impact of embryo selection, enabling very large changes if successfully applied to humans.” – h/t mike anissimov!

Cooperation and conflict between women in the family“Reproductive competition within and between families may have underpinned the biological evolution of fertility patterns (such as menopause) and the cultural evolution of marriage, residence, and inheritance norms (such as late male marriage or primogeniture), which can enhance cooperation and minimize the observed incidence of such conflicts.”

The bone flutes, pictured above, are thought to be the world’s earliest heptatonic musical instruments ever discovered.”

Total Fertility Rate“Oversimplifying, if your tribe has 60 men and 40 women, if each woman has two kids during her lifetime, when the next generation turns over, your population will have declined from 100 people to 80. Conversely, if your tribe has 40 men and 60 women, and each woman has two kids, your tribe will have grown from 100 to 120. The female sex is the limiting factor when it comes to reproduction, after all.” – from the awesome epigone.

Earlier Onset of Puberty in Girls Linked to Obesity“[T]he respective ages at the onset of breast development varied by race, body mass index (obesity), and geographic location. Breast development began in white, non-Hispanic girls, at a median age of 9.7 years, earlier than previously reported. Black girls continue to experience breast development earlier than white girls, at a median age of 8.8 years. The median age for Hispanic girls in the study was 9.3 years, and 9.7 years for Asian girls. Body mass index was a stronger predictor of earlier puberty than race or ethnicity.” – h/t hbd bibliography!

bonus bonus: There’s a global morality gap — and it’s getting wider“It is now clear, though not much talked about, that humanity, all 7.1 billion of us, tends to fall into one of two distinct camps. On the one side are those who buy into the whole post-Enlightenment human rights revolution. For them the moral trajectory of the last 300 years is clear: once we were brutal savages; in a few decades, the whole planet will basically be Denmark, ruled by the shades of Mandela and Shami Chakrabarti. And there’s some truth in this trajectory — except for the fact that it only applies to half the planet. The other half resolutely follows a different moral code: might is right, all men were not created equal and there is a right and a wrong form of sexual orientation. You can identify those countries in the dark half of the divide by their attitudes to homosexuality and women; to honour killings, race, disability, mental illness, religious minorities and to crime, torture and punishment, even animal rights and the environment.” – h/t ed west!

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.

“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.’”

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?

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!

Because of this two-step migration, some Khoe-San groups who were thought to have been genetically quite isolated actually carry 1–5% non-African DNA….”

How the light gets out – re. consciousness: “…the attention schema theory. It says that awareness is not something magical that emerges from the functioning of the brain. When you look at the colour blue, for example, your brain doesn’t generate a subjective experience of blue. Instead, it acts as a computational device. It computes a description, then attributes an experience of blue to itself. The process is all descriptions and conclusions and computations. Subjective experience, in the theory, is something like a myth that the brain tells itself. The brain *insists* that it has subjective experience because, when it accesses its inner data, it finds that information.”

there was a study published in current biology the other day showing that, unlike “neurotypical” kids, autistic kids don’t overimitate after being shown how to do something. from a popular report @livescience:

“Kids with Autism Don’t Copy ‘Silly’ Actions”

“When imitating the behavior of an adult, children with the developmental disorder autism tend to skip ‘silly,’ unnecessary actions, while those without autism tend to copy everything they see, silly or not, a new study suggests.

“The study involved 31 children with an autism spectrum disorder, and 30 typically developing kids without autism. All the children were asked to watch as an adult showed how to remove a toy (a rubber duck) from a closed Tupperware container. Some of the steps performed were necessary, such as unclipping the lid of the box and taking the lid off, while some were unnecessary, such as tapping the lid twice. The children were then given the container, and asked to get the toy out as fast as they could.

“Kids without autism were much more likely to copy the unnecessary steps, even though the children were not specifically instructed to copy everything the adult did. About 43 to 57 percent of kids without autism copied the unnecessary steps, compared with 22 percent of kids with autism….”

the researcher who conducted the study suggests that: “children with autism do things efficiently rather than socially, whereas typical children do things socially rather than efficiently” [my emphasis].

humans are social creatures. in an extreme sort of way (see: the great civilizations). and our sociality has enabled us to do some fantastic things. but it also makes too many humans thick as planks because most humans really, really, really want to follow and belong to the group. whatever the cost (i.e. even if it means being dumber than a chimp).

and woe to those who don’t play along:

“The End of a Bold Experiment: Big Think and Satoshi Kanazawa”

“Over the past few months, across various social media platforms, and also from the mouths of some of our own bloggers, I have listened to a sustained critique of Kanazawa’s presence on Big Think….

“What I hope results from this experience is what educators call a ‘teachable moment.’ We certainly believe in the value of free speech at Big Think, and give voice to controversial thinkers whose opinions tend to span the political spectrum and often challenge the sacred cows of their respective fields…. However, in providing a platform for dangerous ideas, we also run the risk of overreaching and losing the goodwill of our most dedicated readers. Our commitment is first, and always, to you, and to maintaining your trust…”

…’cause we wouldn’t want you to stop LIKING us and exclude us from the in crowd! heavens, no.

what a bunch of … little thinkers! but that’s all most people are capable of, because most people are social, and social belonging trumps all. like i said over here, it really is us contrarians who require explaining because we are the exceptions to the rule!

jared taylor (quoted by john derbyshire) said recently: “Most people are incapable of holding an unfashionable opinion.”

yup.

In addition, the bacteria present in their gut were significantly different from that found in mice without autism-like behaviour. Studies in humans have also identified links between gut bacteria and autism. For example, a 2011 study identified a significant lack of Bacteroides in children with autism.”
