Zigzags on a Shell From Java Are the Oldest Human Engravings“The early human Homo erectus also made the oldest known shell tools half a million years ago.” — see also: The art of Homo erectus“What we can say is that these artifacts carry information about the capabilities of their makers. The few non-perishable marked objects also speak to the likely presence of design in perishable elements of material culture. Clothing, however rudimentary, was likely to have been decorated in some way. Wooden tools were also probably notched and zigzagged — as the occasional bone and ivory implements suggest. They lived for the first time in a world that they could change.” – from john hawks.

Genetic diversity of Sub-Saharan Africa revealed[T]he researchers also found that there were more genetic similarities across Africa than they had thought. Dr Sandhu said: ‘The diversity among populations is not as diverse as we expected it to be….’ The researchers found that many Africans have some Eurasian DNA within their genetic ancestry, which suggests that Eurasians migrated back into Africa many thousands of years after they first left. And several of the populations were descended from the Bantu, a group that spread across Africa about 5,000 years ago.” — see also: The African Genome Variation Project shapes medical genetics in Africa.

and here is dienekes on the above study: African Genome Variation project paper“In too many papers to count, decreasing genetic diversity from East Africa was taken as evidence of an origin of H. sapiens in that locality and its expansion from there to Eurasia. This ‘East Africa=cradle of mankind’ theory has, as far as I can tell, nothing really to stand on. Granted, the oldest anatomically modern human remains have been found in East Africa 200-150 thousand years ago. But, the fact that old sapiens have been found in East Africa and not elsewhere is easily explained by the excellent conditions for preservation (as opposed, e.g., deserts or rainforests of Africa or elsewhere), and by the extraordinary effort by palaeoanthropologists in that area. One also needs to overlook a century of physical anthropology that concluded that East Africa was a contact zone between Caucasoids and Sub-Saharan Africans. We now know that there is no deep lineage of humans in modern east Africans. Take out the Eurasian ancestry and only a paltry Fst=0.027 remains with other Sub-Saharan Africans, a fraction of the Fst between, say, Europeans and East Asians.”

Living African group discovered to be the most populous humans over the last 150,000 years“New genetic research reveals that a small group of hunter-gatherers now living in Southern Africa once was so large that it comprised the majority of living humans during most of the past 150,000 years. Only during the last 22,000 years have the other African ethnicities, including the ones giving rise to Europeans and Asians, become vastly most numerous…. ‘This and previous studies show that the Khoisan peoples and the rest of modern humanity shared their most recent common ancestor approximately 150,000 years ago, so it was entirely unexpected to find that this group apparently did not intermarry with non-Khoisan neighbors for many thousand years….'” — see also The Least Bottlenecked Humans of All from razib.

Ants, altruism and self sacrifice“It’s the selfishness of genes that makes us unselfish…. ‘Group selection’ has always been portrayed as a more politically correct idea, implying that there is an evolutionary tendency to general altruism in people. Gene selection has generally seemed to be more of a right-wing idea, in which individuals are at the mercy of the harsh calculus of the genes. Actually, this folk understanding is about as misleading as it can be. Society is not built on one-sided altruism but on mutually beneficial co-operation. Nearly all the kind things people do in the world are done in the name of enlightened self-interest. Think of the people who sold you coffee, drove your train, even wrote your newspaper today. They were paid to do so but they did things for you (and you for them). Likewise, gene selection clearly drives the evolution of a co-operative instinct in the human breast, and not just towards close kin.” – from matt ridley. — see also: E.O.

Booze culture may date back 10 million years say scientists“A new study suggests that primates may have begun drinking alchol 10 million years ago, as fermented fruit on the forest floor…. Experts at Santa Fe College in the US studied the gene ADH4 which produces an enzyme to break down alcohol in the body. It was hypothesised that the enzyme would not appear until the first alcohol was produced by early farmers. But scientists were amazed to find it 10 million years earlier, at the end of the Miocene epoch.” – (them’s *my* ancestors right there! (~_^) )

Psychiatry: End of the Road for “Endophenotypes”?“In a nutshell, the researchers ran seven different genetic studies to try to find the genetic basis of a total of seventeen neurobehavioural traits, also known as ‘endophenotypes’…. Essentially an endophenotype is some trait, which could be almost anything, which is supposed to be related to (or part of) a psychiatric disorder or symptom, but which is ‘closer to genetics’ or ‘more biologica’ than the disorder itself. Rather than thousands of genes all mixed together to determine the risk of a psychiatric disorder, each endophenotype might be controlled by only a handful of genes – which would thus be easier to find…. Over 89% of the searches came up null in this way; for eight of the seventeen traits, the researchers found no associated genes using *any* strategy.” – from neuroskeptic.

He believes that bipedalism preceded the development of the brain in early humans –and was likely something inherited from smaller apes already used to using their feet to move laterally along branches in trees. Although chimpanzees and bonobos are our closest relatives on the evolutionary tree, they do not represent in their own locomotion good proto-models of what led to human upright posture and walking.”

In this Review, we summarize the key logic behind the RNA World and describe some of the most important recent advances that have been made to support and expand this logic.

The Dark Enlightenment for Newbies“So what is dark about the Dark Enlightenment? Absolutely nothing. The Dark Enlightenment only looks dark in contrast to the blinding (as in, it blinds you) optimism of flash in the pan of blank slate equalism. The things that the DE contend about human nature — that parents naturally favor their children, that sexual attraction is a biological phenomenon, that some people are naturally smarter than others — were all accepted as common sense for most or all of human history. It is the unrealistic utopianism of modern liberalism which is ridiculously absurd. The Dark Enlightenment might be better termed The Return to Normalcy. So the phrase “Dark Enlightenment” might not be the best, but it has received enough attention that I don’t think we should abandon it.” – very nice post from empedocles.

Your Ancestors, Your Fate“The notion of genetic transmission of ‘social competence’ — some mysterious mix of drive and ability — may unsettle us. But studies of adoption, in some ways the most dramatic of social interventions, support this view. A number of studies of adopted children in the United States and Nordic countries show convincingly that their life chances are more strongly predicted from their biological parents than their adoptive families. In America, for example, the I.Q. of adopted children correlates with their adoptive parents’ when they are young, but the correlation is close to zero by adulthood. There is a low correlation between the incomes and educational attainment of adopted children and those of their adoptive parents. These studies, along with studies of correlations across various types of siblings (identical twins, fraternal twins, half siblings) suggest that genetics is the main carrier of social status.” – from gregory clark. see also The Son Also Rises: Surnames and the History of Social Mobility.

Reductionism! Determinism! Straw-man-ism!” The main problem, it seems to me, is a fundamental misunderstanding of what genetics as a science studies and how it relates to the function of complex systems. The following statements are not contradictory: 1. The function of a complex system emerges from the complex and dynamic interactions between all of the components of the system, in a context- and experience-dependent manner. 2. Variation in single components of the system (or in multiple components) can affect how it functions. Geneticists investigate the second question. Showing that variation in Gene X affects the behaviour or outcome of a system is not the same as saying that Gene X fully determines that behaviour or fully accounts for the entire system. Gene X is just a piece of DNA sitting in a cell somewhere – it doesn’t do anything by itself. But a *difference* in Gene X can account for a *difference* in how the system works. – from kevin mitchell.

There’s nothing wrong with looking for ‘gay genes’“The Left loves to tell the Right that it’s anti-science, pointing (not without reason) to the correlation between conservative beliefs and a failure to come to terms with the scientific facts of evolution and human-caused climate change. But there’s a subtler tendency on the Left; a fear of research into human nature, in case the findings are in some way politically uncomfortable.”

The effect of paternal age on offspring intelligence and personality when controlling for paternal trait level [pdf] – “We examined the effect of father’s age at birth on offspring intelligence, head circumference and personality traits. Using the Minnesota Twin Family Study sample we tested paternal age effects while controlling for parents’ trait levels measured with the same precision as offspring’s. From evolutionary genetic considerations we predicted a negative effect of paternal age on offspring intelligence, but not on other traits. Controlling for parental intelligence (IQ) had the effect of turning an initially positive association non-significantly negative. We found paternal age effects on offspring IQ and Multidimensional Personality Questionnaire Absorption, but they were not robustly significant, nor replicable with additional covariates. No other noteworthy effects were found.” – from lars penke.

Reversed hierarchy in the brain for general and specific cognitive abilities: A morphometric analysis“Here, we analyze gray matter with three morphometric indices (volume, cortical surface area, and cortical thickness) at three levels of the intelligence hierarchy (tests, first-order factors, and a higher-order general factor, g)…. The key finding reveals substantial variability in gray matter correlates at the test level, which is substantially reduced for the first-order and the higher-order factors. This supports a reversed hierarchy in the brain with respect to cognitive abilities at different psychometric levels: the greater the generality, the smaller the number of relevant gray matter clusters accounting for individual differences in intelligent performance.” – h/t ben southwood!

A nice bunch of flowers“The general factor of intelligence is strongest at lower levels of intelligence. It may be a case of ‘All neurones to the pump’. When abilities are low, most problems are difficult. In such cases, all resources have to be thrown at the problem. When abilities are higher there is more spare capacity for differentiation of abilities. Brighter persons have a lower proportion of their abilities accounted for by a common factor, even though the have higher absolute abilities.” – from dr. james thompson.

Free will beliefs and motivation to punish“In a paper forthcoming in the Journal of Personality and Social Psychology, Cory J. Clark and co-authors provide evidence that widespread belief in the existence of free will is bolstered by a fundamental desire to punish wrongdoers…. As Clark et al. put it, ‘There seems little doubt that the subjective experience of choosing and acting supports people’s belief in free will, but our findings suggest another powerful motivating factor: the human impulse to blame and punish. People believe in free will – at least in part – because they wish to affirm that people who do immoral things could have and should have acted differently’.”

Our results show that most of these Bantu-speaking populations are genetically very homogenous, with no genetic division between speakers of Eastern and Western Bantu languages. Most of the mtDNA diversity in our dataset is due to different degrees of admixture with autochthonous populations.”

in the dark about the dark enlightenment

so, there were a couple of hit pieces on the dark enlightenment — and human biodiversity — in the telegraph this week:

“Meet The Dark Enlightenment: sophisticated neo-fascism that’s spreading fast on the net”

“It started, suitably enough, with two blogs. Mencius Moldbug, a prolific blogger and computer whizz from San Francisco, and Nick Land, an eccentric British philosopher (previously co-founder of Warwick University’s Cybernetic Culture Research Unit) who in 2012 wrote the eponymous ‘The Dark Enlightenment’, as a series of posts on his site. You can find them all here.

“The philosophy, difficult to pin down exactly, is a loose collection of neo-reactionary ideas, meaning a rejection of most modern thinking: democracy, liberty, and equality. Particular contempt is reserved for democracy, which Land believes ‘systematically consolidate[s] and exacerbate[es] private vices, resentments, and deficiencies until they reach the level of collective criminality and comprehensive social corruption.’

The neo-fascist bit lies in the view that races aren’t equal (they obsess over IQ testing and pseudoscience that they claim proves racial differences, like the Ku Klux Klan) and that women are primarily suited for domestic servitude. They call this ‘Human biodiversity’ – a neat little euphemism….

no, they don’t — or that’s not what human biodiversity means, anyway — but never let the facts get in the way of a good story, right?

“This links directly to their desire to be rid of democracy: because if people aren’t equal, why live in a society in which everyone is treated equally? Some races are naturally better to rule than others, hence their support for various forms of aristocracy and monarchy (and not in the symbolic sense but the very real divine-right-of-kings-sense).

this particular blog post (the piece appears in the telegraph’s blog section) was written by jamie bartlett who is at the u.k. think-tank demos. (demos was founded by a guy who had been editor of “Marxism Today,” the “theoretical magazine of the Communist Part of Great Britain,” so i’m sure there are no biases at demos, right??)

on twitter, and on the telegraph, bartlett describes himself as “Director of Centre for the Analysis of Social Media at Demos”. which is true. but on the demos website, he’s also — firstly — described as being the “Head of the Violence and Extremism Programme” and that his “primary research interests are: terrorism, extremism and social media analysis…”, so, you know — he’s obviously got a hard-on for The Bad Guys. (i don’t know at all whether he does or not, but i hope he’s keeping an eye on left-wing extremists, too!)

the other article (blog post) was by tim stanley:

“The ‘neo-fascist’ Dark Enlightenment is more sad than scary”

“Jamie reports that there is a ‘neo-fascist’ element to this because they ‘obsess over IQ testing and pseudoscience that they claim proves racial differences’. Presumably, this is because they are anti-egalitarian and would argue that nature makes us unequal, which is one more reason why democracy is a sham. The weak and idiotic ally together to form a majority and rip off the intelligent minority. Now, can anyone remember who John Galt is…?

“That these ‘neo-reactionaries’ admire monarchies is what makes they seem way-out and new….

“However, there is a distinctly unlibertarian note of crazy about the neo-reactionary interest in IQ. Aside from the bad science and the irony of being anti-statist yet sympathetic to the idea that you can measure intelligence and use it to justify social policy – it does also set off ‘white rights’ alarms bells….

“*There is no line to be walked between reason and racism.* Racism and biological determinism are unscientific and immoral, and they have no place in a sane philosophy.”

yeah, i know — even more confused than bartlett’s blog post. but, then, stanley is under the impression that lactose intolerance is a preference and not something biological:

tim stanley tweet

dr. stanley is an historian, which is great! i’m all for knowing and understanding as much as possible about history. but i think he really does need to put down the history books for a few weeks and read up on biology. might actually help him understand human history a bit more!
_____

so, the dark enlightenment = neoreaction = monarchism = human “bad science” diversity = neo-fascism.

NOT!

lemme see if i can help to clear this all up for these fellows.

last time i checked, which admittedly was over half a year ago, the dark enlightenment was a broad, umbrella term for several current schools of thought, one of them being neo-reaction, a subset of those being monarchists. what everyone in the dark enlightenment shares in common is an understanding and acceptance of human biodiversity, i.e. the diversity found among and between human populations that has a biological basis. (i pretty much stole that lovely, succint definition from caitlin s. i’ll be writing more on what, exactly, human biodiversity is in the coming weeks — apparently the world needs that — so stay tuned those of you who don’t know already!)

sharlach drew up a really great map of the dark enlightenment for the nsa all of us last april (there might be a more updated map — i dunno — i haven’t been following the discussion that closely – click on map for LARGER view):

darkenlightenment1

see? there’s more to the dark enlightenment than monarchist neo-reactionaries. not that there’s anything wrong with monarchist neo-reactionaries! god luv ’em. i just happen not to be one of them. (unless, of course, i get to be queen — and get to wear outfits like queen elizabeth’s. the first one, i mean.)
_____

the term “the dark enlightenment” is clearly a reference to the enlightenment, and i’ve always thought the meaning would be fairly obvious: the conclusions of the eighteenth century enlightenment thinkers were pretty much based upon ideas like “man is a rational creature” and “all men are created equal.” the problem is, today’s science is showing over and over again that neither of those two premises is correct — far from it (unfortunately)! humans are not rational and we don’t all have the same abilities. these revelations (from science) are disappointing, ergo the use of “dark” as our descriptor.

additionally, the enlightenment didn’t spawn just one political or social ideology, it gave rise to many. same with the dark enlightenment. you and i might agree on the facts of human biodiversity, but we might have different ideas as to how to apply that knowledge: some go for redistributing wealth more from the capable to the not-so-capable, some might suggest ways to improve education, others might just want to enhace their pick-up-artistry skillz. so, not everyone connected to the dark enlightenment are “neo-fascists” — although my guess is that the use of the word by bartlett and stanley was just meant as an insult.

when nick land first coined the term, many folks in these quarters of the internet objected for various reasons. i liked the term right away — still do! but, then, like this other chick, i’ve always been rather drawn to the dark side. (shut-up, roissy! (~_^) )

Calcium absorption not the cause of evolution of milk digestion in Europeans“‘The evolution of lactase persistence is one of the best known and most dramatic examples of recent human evolution. One of the ironies of working in this area is that we know it happened but we still don’t fully know why’ says Sverrisdóttir. Lactase persistence is found at highest frequencies in southern Sweden and in Ireland. Given that calcium absorption is not the only reason why this trait evolved so rapidly, Sverrisdóttir and colleagues have proposed another cause: Although most early European farmers would not have been lactase persistent, they would still have been able to consume fermented milk products such as yoghurt and cheese, because fermentation converts much of the lactose into fats. But in famine conditions, such as when crops fail, they are likely to have eaten all the fermented milk foods, leaving only the more high-lactose products. This would have caused the usual lactose intolerance symptoms such as diarrhea. Diarrhea in in healthy people is not usually life-threatening, but in severely malnourished individuals it certainly can be. So famine could have led to episodes of very strong natural selection favoring lactase persistence.”

Human and Helicobacter pylori coevolution shapes the risk of gastric disease“Patients were recruited from two geographically distinct Colombian populations with significantly different incidences of gastric cancer, but virtually identical prevalence of H. pylori infection. All H. pylori isolates contained the genetic signatures of multiple ancestries, with an ancestral African cluster predominating in a low-risk, coastal population and a European cluster in a high-risk, mountain population. The human ancestry of the biopsied individuals also varied with geography, with mostly African ancestry in the coastal region (58%), and mostly Amerindian ancestry in the mountain region (67%). The interaction between the host and pathogen ancestries completely accounted for the difference in the severity of gastric lesions in the two regions of Colombia. In particular, African H. pylori ancestry was relatively benign in humans of African ancestry but was deleterious in individuals with substantial Amerindian ancestry. Thus, coevolution likely modulated disease risk, and the disruption of coevolved human and H. pylori genomes can explain the high incidence of gastric disease in the mountain population.”

Seeing X Chromosomes in a New Light“X-chromosome inactivation, Dr. Nathans’s pictures show, creates a genetic diversity that’s particularly dramatic. Two cells side by side may be using different versions of many different genes. ‘But there is also much larger-scale diversity,’ Dr. Nathans said. In some brains, for example, a mother’s X chromosome was seen dominating the left side, while the father’s dominated the right. Entire organs can be skewed toward one parent. Dr. Nathans and his colleagues found that in some mice, one eye was dominated by the father and the other by the mother. The diversity even extended to the entire mouse. In some animals, almost all the X chromosomes from one parent were shut; in others, the opposite was true.”

Are plants altruistic?“Roots can distinguish self from other, and they know their own kind (species), they can share resources and information about insect attacks and deliver nutrients to trees in need. The preponderance of evidence does seem to suggest that plants are proactive in filling their own needs and the needs of others.” – ooooh, not just their own species, their own close relatives! – see also The Intelligent Plant.

Sluggish metabolisms are key to primates’ long lives“[P]rimates expend 50 per cent less energy than other mammals of equivalent mass during an average day. ‘What’s more, he says the difference is not easily explained by differing activity levels: a human would need to run a whole marathon every day to be on an even energetic footing with mammals that aren’t primates….’ The finding offers a completely new way to understand why primates have slower life histories than other mammals of equivalent body size…. Pontzer thinks that the slower metabolism may have evolved to help primates cope with food shortages. For instance, orang-utans suffer frequent famines. ‘Orang-utans experience extended periods of low fruit availability,’ says Vogel. ‘There are months when caloric intake is less than expenditure – and they burn body fat stores.’ A slow metabolism might help them survive.”

Triune origins“With the latest paper, the story on European origins is becoming clearer. Three populations account for European ancestry: the Mesolithic hunter-gatherers of western Europe (dubbed WHG in the paper), early European farmers derived from somewhere in the Mideast (EEF), and a third group more closely related to ancient Siberians (ANE) than any existing population. Those Sibermen also contributed a third of Amerindian ancestry, the rest being similar to modern East Asian populations.” – from greg cochran.

The first industrial revolution“As early modern humans spread farther north, they entered more challenging environments…. Did these new cognitive demands have an evolutionary impact? Did they select for certain mental capacities over others? Piffer (2013) has addressed these questions by seeing how hunter-gatherers differ from farming peoples in alleles at COMT, a gene linked to executive function, working memory, and intelligence…. Northern hunting peoples, however, differ from other hunter-gatherers and resemble more advanced farming populations.” – from peter frost.

‘Out of Africa’ gene mutation in human pigmentation increases predisposition to skin cancer“The V60L mutation is more common in people with light hair and skin tone that, despite being light, tans easily in the summer. This mutation is positive for the climate of the Mediterranean region, as it facilitates the absorption of vitamin D in the winter months, in which the ultraviolet radiation is lower. In the summer months, in which the radiation is greater, the ease to darken the skin pigmentation provides a certain protection. However, the study also revealed that among people with this mutation there is a greater predisposition to skin cancer.” – see also: Simultaneous Purifying Selection on the Ancestral MC1R Allele and Positive Selection on the Melanoma-Risk Allele V60L in South Europeans.

Changes in Thickness and Surface Area of the Human Cortex and Their Relationship with Intelligence“At 10 years of age, more intelligent children have a slightly thinner cortex than children with a lower IQ. This relationship becomes more pronounced with increasing age: with higher IQ, a faster thinning of the cortex is found over time. In the more intelligent young adults, this relationship reverses so that by the age of 42 a thicker cortex is associated with higher intelligence. In contrast, cortical surface is larger in more intelligent children at the age of 10. The cortical surface is still expanding, reaching its maximum area during adolescence. With higher IQ, cortical expansion is completed at a younger age; and once completed, surface area decreases at a higher rate. These findings suggest that intelligence may be more related to the magnitude and timing of changes in brain structure during development than to brain structure per se, and that the cortex is never completed but shows continuing intelligence-dependent development.”

Why do spatial abilities predict mathematical performance?“About a third of the variation in spatial ability at age 12 is explained by genetic factors; a little less than half of the variation in mathematics at this age is genetic. We find no sex differences in the genetic and environmental influences (either in magnitude or type) on mathematical and spatial variation at age 12. The observed overlap between spatial ability and mathematics is substantial (r > .40). Approximately 60% of this overlap is explained by common genetic effects, with 40% of the overlap due to environmental experience.” – h/t DOCTOR stuart ritchie! (^_^)

New evidence shows the FDA was wrong to halt 23andMe testing“While the tests are often too inaccurate for consumers to consider them diagnoses, research shows that most customers will seek a doctor’s opinion before taking action, anyway. According to the authors’ research, 58% of 1,051 surveyed customers did nothing at all with their genomic results. Of the 42% who made health decisions based on the information, only 2% changed prescription drug regimens without consulting a physician. The majority of customers who made changes focused on diet, exercise, and vitamins.”

Dogs’ Closest Wolf Ancestors Went Extinct, Study Suggests” A new genetic analysis of modern dogs and wolves suggests that man’s best friend was domesticated before agriculture. But the origin of this domestication remains stubbornly mysterious. Researchers analyzed the genomes of wolves from three likely sites of domestication (the Middle East, Asia and eastern Europe), and found that modern dogs were not more closely related to any of the three. In fact, it seems that the closest wolf ancestors of today’s dogs may have gone extinct, leaving no wild descendants.” – also: Paedomorphic Facial Expressions Give Dogs a Selective Advantage – woof! – h/t claire lehmann!

Eye of the Tiger PeopleBut what the hell is ‘culture,’ anyway? Talk about a social construct! Even the term ‘social construct’ is a social construct, one unique to our culture. And who’s to say culture is entirely separate from genetics? There’s some suggestion that the two may be intimately intertwined. In rawest terms, ‘culture’ may be nothing more than what happens when a group’s genes interact with their environment. – from jim goad.

Toddlers’ aggression is strongly associated with genetic factors, study reports“The development of physical aggression in toddlers is strongly associated genetic factors and to a lesser degree with the environment, according to a new study led by Eric Lacourse of the University of Montreal and its affiliated CHU Sainte-Justine Hospital.

Apes are intuitive statisticians“Here, we conducted the first investigation of such intuitive statistical reasoning with non-human primates. In a series of 7 experiments, Bonobos, Chimpanzees, Gorillas and Orangutans drew flexible statistical inferences from populations to samples. These inferences, furthermore, were truly based on statistical information regarding the relative frequency distributions in a population, and not on absolute frequencies. Intuitive statistics in its most basic form is thus an evolutionarily more ancient rather than a uniquely human capacity.” – iow, the other great apes outperform a lot of humans (i.e. the pc ones)!

More than 20 percent of Iranian couples cannot conceive, according to a study conducted by one of the country’s leading fertility clinics, compared with the global rate of between 8 and 12 percent. Experts believe this is due to the prevalence of consanguineous marriages, or those between cousins. Male infertility is ‘the hidden story of the Middle East,’ says Marcia Inhorn, a Yale University medical anthropologist and a specialist on assisted reproduction in the region.”

Patterns of selection on Neanderthal alleles in modern humans“‘We identified Neandertal alleles that are at higher frequency than expected under a model of neutral evolution, and identify dozens of genomic locations in Europeans and East Asians at which the Neandertal alleles are the targets of positive selection.
