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.

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.

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.

Capturing a Hard-Wired Variability: What Makes Some Identical Twins Noticeably Different?“The current study finds that only one allele is expressed in between 12 and 24 percent of all such pairs encoded by the mouse genome. Further, the selection of expressed alleles varies randomly from cell to cell, and switches frequently between the two options throughout their lives…. ‘We find that for those genes that are not imprinted, roughly one in five alleles is randomly and dynamically expressed only one at a time,’ says Sandberg. ‘And if one allele is being expressed, the other doesn’t know about it. There’s no coordination between two.'”

A Living Time Capsule Shows the Human Mark on Evolution“Scientists have revived shrimp-like animals that have been buried at the bottom of the lake for an estimated 700 years. If this estimate holds up to further testing, they are the oldest animals ever resurrected…. The oldest DNA the scientists obtained from the lake dates back to around the time the Vandals were ransacking Rome. The scientists found that one genetic strain of water fleas dominated at the time — and continued to until the late 1800s. As phosphorus [from fertilizers] flooded the lake, a previously rare strain emerged and took over.”

Evolution Hidden in Plain Sight“One of the hallmarks of *Escherichia coli* as a species is that when there’s oxygen around, it can’t feed on a compound called citrate. But one day a flask turned cloudy with an explosion of *E. coli* that were doing just that. The change was so profound that it may mean these bacteria had evolved into a new species.”

SLC24A5 light skin pigmentation allele origin“‘The distributions of C11 and its parental haplotypes make it most likely that these two last steps occurred between the Middle East and the Indian subcontinent, with the A111T mutation occurring after the split between the ancestors of Europeans and East Asians.'” – @dienekes’.

Factor Analysis of Population Allele Frequencies as a Simple, Novel Method of Detecting Signals of Recent Polygenic Selection: The Example of Educational Attainment and IQ [pdf] – “Frequencies of 10 SNPs found to be associated with educational attainment in a recent genome-wide association study were obtained from HapMap, 1000 Genomes and ALFRED. Factor analysis showed that they are strongly statistically associated at the population level, and the resulting factor score was highly related to average population IQ (r=0.90). Moreover, allele frequencies were positively correlated with aggregate measures of educational attainment in the population, average IQ, and with two intelligence increasing alleles that had been identified in different studies.” – h/t elijah! see also jayman.

Ancient hunter-gatherers had rotten teeth“Scientists have long thought that tooth decay only became common in humans about 10,000 years ago, when we began farming – and eating starchy crops that fed sugar-loving bacteria on our teeth. But Isabelle De Groote of the Natural History Museum in London, UK, and her colleagues have found widespread tooth decay in hunter-gatherers that lived several thousand years before the origin of agriculture.”

Is the dark side of parenting genetic?“In a novel finding, Robert Plomin and colleagues suggest that negative aspects of parenting are more heritable than positive aspects. They call this The Dark Side of parenting. The effect is interesting and subtle: it suggests that whilst parents are generally consistent in their handling of their children, some genetically driven characteristics of their children lead them into more negative parenting styles…. In simple terms, even peaceable parents get irritable with difficult children.” – from dr. james thompson.

Do Elite ‘Power Sport’ Athletes Have a Genetic Advantage?“A specific gene variant is more frequent among elite athletes in power sports…. A ‘functional polymorphism’ of the angiotensiogen (AGT) gene is two to three times more common in elite power athletes, compared to nonathletes or even elite endurance athletes, according to the new research by Paweł Cięszczyk, PhD, of University of Szczecin, Poland, and colleagues.”

Ballet Dancers’ Brains Adapt to Stop Them Getting in a Spin – or maybe they start off with somewhat different brain structures: “Scientists have discovered differences in the brain structure of ballet dancers that may help them avoid feeling dizzy when they perform pirouettes…. The brain scans revealed differences between the groups in two parts of the brain: an area in the cerebellum where sensory input from the vestibular organs is processed and in the cerebral cortex, which is responsible for the perception of dizziness. The area in the cerebellum was smaller in dancers.”

Math explains history: Simulation accurately captures the evolution of ancient complex societies“The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence of complex states in the ancient world.

(party pooper.)

Genetic study pushes back timeline for first significant human population expansion“Using new genetic tools, the authors conclude that the first significant expansion of human populations appears to be much older than the emergence of farming and herding, dating back to the Paleolithic (60,000-80,000 years ago) rather than Neolithic age (10,000 years ago). They also suggest that strong Paleolithic expansions may have favored the emergence of sedentary farming in some populations during the Neolithic.” – h/t malcolm pollack!

New Approach to Explaining Evolution’s Big Bang“[T]he Cambrian Explosion was preceded by a rise in sea level that submerged vast swaths of land, eroding the drowned rocks…. But these great floods also poisoned the ocean. The erosion of the coastlines released calcium, which can be toxic to cells. In order to survive, animals had to evolve ways to rid themselves of the poison. One solution may have been to pack the calcium into crystals, which eventually evolved into shells, bones, and other hard tissues. Dr. Smith doesn’t think it’s a coincidence that several different lineages of bilaterians evolved hard tissues during the Cambrian explosion, and not sooner.”

Understanding how infants acquire new words across cultures“[I]n English, 24-month-old infants were better able to learn novel verbs for novel actions (e.g., petting) if the surrounding noun phrases were explicitly mentioned (e.g., ‘The girl is petting the dog’) than if they were dropped from the sentence (e.g., ‘Look. Petting!’). In contrast, the new research shows that in Korean (a language in which noun phrases are typically dropped in conversation) 24-month-olds were better able to learn novel verbs for novel actions if the surrounding noun phrases (e.g., the girl, the dog) were dropped; in fact, unlike English-acquiring infants, those acquiring Korean struggled if the nouns were explicitly mentioned.” – don’t know, unfortunately, what the ethnicities of these infants are.

The Science Fiction Future of Genetic Genealogy“Next month at the American Society of Human Genetics 2013 meeting, researchers from AncestryDNA will present their work detailing the reconstruction of portions of the genomes of an 18th-century couple using detailed genealogical information and Identity-by-Descent (‘IBD’) DNA segments from several hundred descendants of the couple in the AncestryDNA database. In other words, researchers identified several hundred descendants of a certain couple living in the 1700s and then used the DNA shared by those descendants to recreate as much of the couples’ genomes as possible.” – cool! from the genetic genealogist.

Low-Hanging Fruit: Consider the Ant“Some spiders somehow fly by using silken threads. They’ve been detected at altitudes over 4 km, and more than a thousand miles from land. The usual notion is that these threads catch air currents, but that may not be the real explanation. For one thing, they seem to be able to take off fairly rapidly in a dead calm. It looks instead as if these spiders manage to impart a negative charge to these threads and are then propelled upward by the atmospheric electric field – electrostatic levitation, a totally novel mechanism for flight.” – whoa! – from greg cochran.

Brainwashed by a microbe?“*T. gondii* is being studied for possible behavioral effects mainly because it has attracted so much attention.

These organisms are, however, still waiting for research teams to engage in a systematic study of their influence on the human host.'” – from peter frost. previously.

the time bill hamilton almost got watsoned

well, he actually wasn’t anywhere near being watsoned since he committed his politically incorrect faux pas in the early 1980s, but he did get a good telling off. he definitely would’ve been booted out today, though.

he thought political correctness was stupid, and his swpl-lady-accuser — well, i dunno what he thought of her, but i think she’s stupid. what on earth would he have made of our situation today?

from “Narrow Roads of Gene Land, Vol. 2” [pgs. 303-04, 307-09]:

“By 1984 two aspects of life in the USA had made me feel differently [about moving back to the uk]. One was the level of violence — this was felt even in a seemingly rural university town like Ann Arbor….

“The other main incentive for the move was also a ‘rising level’ and this had changed in the 2 years [since the last offer of a job in the uk], and was about as depressing for me as the violence. I see it now as the beginning of what came to be called ‘political correctness’, but then it just seemed an increasing intolerance about how others lived and spoke, a rising pressure to conformity. Mountain men in remote valleys might escape the new social climate but one couldn’t in Ann Arbor….

“While the ‘anti-smoke’ pollution of human freedom was one factor pushing me to Britain in the early 1980s it still wasn’t the most significant event telling me I was getting seriously out of touch with America and was going to find it difficult just to be myself if I remained there. Rather it was the experience of being telephoned by a lady academic…”

… ugh. you just know it’s going to be bad …

“…to talk to me about a letter I had sent to her department recommending one of my graduate students for an advertised post. She told me that phrases I had used were very harmful both to the student’s chances and to my own reputation. Because I had taken great care in writing the letter and considered it to contain, in fact, the strongest support I had ever given to any student, I was immediately dismayed and puzzled. I was soon enlightened by her where the trouble lay. I had written to the effect that the student was ‘exceptionally strong on the theoretical and statistical side and with an ability especially remarkable in view of her sex and non-mathematical background’….”

… heh …

“…The offending words will be obvious to anyone today: my informant made it clear to me that I ought to have treated the student as if I had never noticed its gender.

“Hundreds of experiences have taught me that women are not as good on average at maths and spatial problems as men. This matter seemed really to need no statistical tests although plenty have been recorded. In a related field, day-to-day orientation, many women seem almost to boast about their tendency to get lost in towns and buildings: very few men do. The entire sweep of history as I knew it suggested to me the same things, and the difference continues even right up to the present in spite of all the recent equalizing forces that have been applied. Even in rats females have been shown to be less good at spatial and route-finding tasks than males although why this should be is still largely a mystery. As always, of course, the overlap of abilities is wide and there are innumerable women who are much better mathematicians and visualizers than innumerable men — I could name many who are better than me. For sure also, plenty of good women engineers, physicists, and the like are qualifying where there exists the will to enter these activities. Still, the average difference remains for me striking and is confirmed through a multitude of channels. Aptitude tests performed on small children are just the start of them. Nowadays some parents make a special point of trying to override any cultural bias that may have existed in erstwhile courses of infancy and childhood and I, too, have made my own small intrafamily attempts, out of interest, to see if the tendency could be overridden (diagrams of theorems of Euclid pinned inside the hood of one daughter’s perambulator formed a part of one experiment). But neither I nor others who have tried it, I think, can record much success (my daughter, however, did pass advanced-level school maths).

“Anyway, consequently I didn’t believe the theory that the difference comes wholly from cultural factors, and I assumed that, in spite of all the outcry of a few based so far as I could see on very flimsy evidence and excuses, most intelligent people of both sexes would interpret my letter the same way as I meant it. Holding this expectation, I had wanted to be sure my student would not be automatically devalued by a reader of my letter who might interpret it as a more vague complement: ‘Exceptional,’ he says, but he means no doubt ‘as women go’ — who wouldn’t leave this unsaid of his own student?’ I had added the phrase to forestall this, to make clear that I was aware of the average difference and nevertheless gave unqualified praise. I assumed any ‘search’ committee would understand this and that it would raise, not lower, my student’s chance. I still can hardly credit that what I wrote would be interpreted in any other way…. But in the gathering new climate — in which, by analogy, I suppose you are not supposed to mention in a letter that you happen to have noticed that a student has the handicap of being blind — they were not harmless: some acid remarks from the person on the phone made this plain when, amazed, I tried to explain what I had meant….

“The end result was that I decided, rather as I had done at Cambridge when I had been told there was no possible connection between genetics and social anthropology, that I should try to pursue my career as a misogynist somewhere else with the corollary to this decision that I needed to be careful about taking on more graduate students generally if my best efforts were going to harm them in ways I had become too socially blind to see.”

reading this account reminded me of something pat buchanan wrote just the other day — The Equality Racket:

“And here is the unvarying argument of the left since Karl Marx: If you give us power, we will take from the rich who have so much and give it to you who have so little. But before we can do that, you must give us power.

“This is the equality racket. As Alexis de Tocqueville wrote:

“‘The sole condition which is required in order to succeed in centralizing the supreme power in a democratic community, is to love equality, or to get men to believe you love it. Thus the science of despotism, which was once so complex, is simplified, and reduced … to a single principle.’

When they come preaching equality, what they want is power.

uh-huh.

hbd chick’s conservative canon

so, this weekend the mencken club is discussing what ought to be in the conservative canon. i’m not there (alas, alack), but here’s my list of essential conservative reading:

On the origin of species by means of natural selection, or the preservation of favoured races in the struggle for life – charles darwin (wouldn’t hurt to read some or all of his other books as well).

Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thoughtgeorge c. williams.

The Selfish Gene – richard dawkins. (just ignore the politically correct bits.)

edit: Sociobiology: The New Synthesis – e.o. wilson.

Narrow Roads of Gene Land, Vol. 1william d. hamilton. go ahead and read volume 2 as well. (it’s all about sex! (~_^) )

edit: The Blank Slate – The Modern Denial of Human Nature – steven pinker.

The 10,000 Year Explosion: How Civilzation Accelerated Human Evolution – greg cochran and henry harpending.

– read and learn all the biology you possibly can. this goes for chemistry and physics, too. edit: and history, too!

– learn as much maths as you can stand, and them some.

– read steve sailer every day. ok, ok — a couple of times every day.

– read all of sam francis.

– read all of pat buchanan.

– read all of jared taylor.

then i think you’ll be in pretty good shape. (^_^)

“Blacks struggle with 72 percent unwed mothers rate”“The black community’s 72 percent rate eclipses that of most other groups: 17 percent of Asians, 29 percent of whites, 53 percent of Hispanics and 66 percent of Native Americans were born to unwed mothers in 2008, the most recent year for which government figures are available.
