Baffling 400,000-Year-Old Clue to Human Origins – denisovans in SPAIN 400,000 years ago! cool. – see also 400 thousand year old human mtDNA from Sima de los Huesos from dienekes. – and see also Hominin DNA baffles experts.

Snakes outpacing other vertebrates in race to evolve“The first two full snake genomes to be sequenced – belonging to the Burmese python and the king cobra – show that they have one of the fastest rates of genetic evolution among vertebrates.”

Earliest Stone-Tipped Projectiles from the Ethiopian Rift Date to >279,000 Years Ago“Projectile weapons (i.e. those delivered from a distance) enhanced prehistoric hunting efficiency by enabling higher impact delivery and hunting of a broader range of animals while reducing confrontations with dangerous prey species. Projectiles therefore provided a significant advantage over thrusting spears…. Direct evidence for such projectiles is thus far unknown from >80,000 years ago. Data from velocity-dependent microfracture features, diagnostic damage patterns, and artifact shape reported here indicate that pointed stone artifacts from Ethiopia were used as projectile weapons (in the form of hafted javelin tips) as early as >279,000 years ago.” – see also Oldest Javelins Predate Modern Humans, Raise Questions on Evolution – h/t naturalismo! – and see also Stone tipped spears used 500,000 years ago – thrusting ones, tho.

Discovery of partial skeleton suggests ruggedly built, tree-climbing human ancestor“Massive arm bones provide insight into how ‘robust’ P. boisei species, found by Leakey, adapted in Africa.”

Iberian Neolithic farmer DNA“‘The Neolithic Portalón individual is genetically most similar to southern Europeans, similar to a Scandinavian Neolithic farmer and the Tyrolean Iceman. In contrast, the Neolithic Portalón individual displays little affinity to two Mesolithic samples from the near-by area, La Brana, demonstrating a distinct change in population history between 7,000 and 4,000 years ago for the northern Iberian Peninsula.’” – @dienekes’.

How genetics are rewriting the history of the Caribbean“The Spanish who arrived in the New World were de facto polygamists who killed or enslaved the local men and impregnated the women.” – from razib.

Male and female brains wired differently, scans reveal“Maps of neural circuitry show women’s brains are suited to social skills and memory, men’s perception and co-ordination…. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, in contrast to men’s brains, where the connections were typically stronger between the front and back regions.” – see also Sex differences in the structural connectome of the human brain. – and see also Stop the Presses! from malcolm pollack. (^_^)

Promiscuity Is Pragmatic“Why women and other female primates seek out multiple partners…. [T]here are two environmental contexts where women commonly choose multiple partners. The first is where women have more material support from their kin or economic independence from men more generally. This may explain why multiple mating is most common among small-scale matrilocal societies (in which women remain in their home village after marriage), such as the partible paternity societies of South America or the Mosuo of China. It may also explain why female infidelity has increased in Western societies as women have gained greater political and economic independence…. The second environmental context Scelza identified is where the sex ratio is female-biased (indicating a scarcity of men) or there is a high level of male unemployment (indicating a scarcity of men who can provide support).” – one for the gameboyz.

Our IQs Are Climbing, But We’re Not Getting Smarter – re. woodley and armstrong paper.

Academic experts criticise Boris Johnson IQ claims“Dr James Thompson, senior lecturer in psychology at University College London, said Boris had been ‘inelegant’ in his choice of words. Thompson, co-author of Cognitive Capitalism, said: ‘What Boris Johnson has done is inelegantly describe things which in fact do seem to be true: intelligence, however you assess it, is predictive. It’s predicative of income, life span and of occupational status. People are different and have different futures and intelligence seems to be an important part of that.’ He said studies showed there seemed to be a correlation between ‘being bright in youth and doing well in life later’. Asked if inequality was inevitable, he said: ‘In one way that is true. There’s two things, one is that some people are brighter than others and can do more complicated work and that more complicated work is generally more valued.’ However, he added that how much people should be paid was a decision for society. Professor Richard Lynn, co-author of IQ and the Wealth of Nations, said that the association between IQ and income was ‘only modest’. ‘That is because some high IQ people go into jobs that don’t have particularly high earnings like university professors, schoolteachers or social workers. Some professions attract very high IQ people but they don’t have very high earnings,’ he said. ‘You could say that the IQ is only one determinant of high earnings, the others are ambition and motivation and the third one is luck.’” – h/t holtz!

The 7 tribes of intellect – from dr. james thompson.

Morality and the State“In general, ‘virtuous’ states – those free of corruption, that do not cheat or steal from their citizens, and that are effective in enforcing laws that are perceived as just – are more effective at promoting the common weal than their opposites. Heraclitus’ dictum that ‘character is destiny’ likely applies to states as well as individuals. I personally think that states are far more likely to be ‘virtuous’ in that sense if their powers are carefully circumscribed and limited.”

Could absence of a father permanently rewire the brain? – from mr. mangan, esq.

Investigation reveals black market in China for research paper authoring“The journal Science has uncovered, via investigation, a thriving black market in science paper authoring—people are paying to have their names added to papers that have been written to describe research efforts…. All in all, the investigative team contacted 27 agencies involved in helping researchers get their work published—only five of them refused an offer to pay for adding a name to a research paper.”

Does Nyborg’s study make sense?“One other thing bothers me. So please let me say it. Why must the Danes prove that they deserve to keep their country to themselves? Isn’t that a basic right? They have only one land to call home…unlike the many ‘refugees’ who regularly visit their own homelands. Once the Danes lose majority status in their country, they’ll be like the Copts of Egypt and other minorities in this world. They’ll have to live by their wits, trying to balance off one potential enemy against another.” – hear, hear! – from peter frost.

Migration Hurts the Homeland“The migration that research shows is unambiguously beneficial is the kind in which young people travel to democracies like America for higher education and then go home. Not only do these young people bring back valuable skills directly learned in the classroom; they bring back political and social attitudes that they have assimilated from their classmates. Their skills raise the productivity of the unskilled majority, and their attitudes accelerate democratization…. Many on the left, for their part, don’t like to recognize that we’re taking away fairy godmothers. They prefer to believe that they’re helping poor people flee difficult situations at home. But we might be feeding a vicious circle, in which home gets worse precisely because the fairy godmothers leave. Humanitarians become caught up trying to help individuals, and therefore miss the larger implications: There are poor people, and there are poor societies. An open door for the talented would help Facebook’s bottom line, but not the bottom billion. – h/t michael story!

Flies see the world in slow motion, say scientists“Flies avoid being swatted in the same way Keanu Reeves dodges flying bullets in The Matrix, by watching time pass slowly, research suggests. The smaller an animal is, and the faster its metabolic rate, the slower time passes for it, scientists found. This means that across a wide range of species, time perception is directly related to size, with animals smaller than us seeing the world in slow motion…. ‘It’s tempting to think that for children time moves more slowly than it does for grown ups, and there is some evidence that it might…. People have shown in humans that flicker fusion frequency is related to a person’s subjective perception of time, and it changes with age. It’s certainly faster in children.’ – mind. blown.

Poverty Can Trump a Winning Hand of Genes“When psychologists first started studying twins, they found identical twins much more likely to have similar IQs than fraternal ones. They concluded that IQ was highly “heritable”—that is, due to genetic differences. But those were all high SES twins. Erik Turkheimer of the University of Virginia and his colleagues discovered that the picture was very different for poor, low-SES twins. For these children, there was very little difference between identical and fraternal twins: IQ was hardly heritable at all…. Richer children have similarly good educational opportunities, so genetic differences among them become more apparent…. But for poor children, haphazard differences in educational opportunity swamp genetic differences.”

Shy male birds keep closer ‘friends’“Shy male great tits have fewer ‘friends’ but build stronger bonds than bolder birds, researchers have found.” – speaking of birds: Warblers begin migrating after interbreeding.

Pornography addiction leads to same brain activity as alcoholism or drug abuse, study shows“Cambridge University scientists reveal changes in brain for compulsive porn users which don’t occur in those with no such habit.”

Redneck Psychiatrists“Schizophrenia is more common in men than women – about 1.4 to 1. It’s more common in the lowest SES groups, although that may be downward drift. Schizophrenia is considerably more common among people of African ancestry…. Schizophrenia seems to be more common among people that grew up in cities – about twice as common.” – from greg cochran.

Stronger Sexual Impulses, Not Weaker Self-Control, May Explain Why Men Cheat More Than Women, Study Reveals

Painful and extreme rituals enhance social cohesion and charity“The study of 86 males in Mauritius found both observers and performers of the Kavadi were more charitable than those who only participated in the collective prayers. The researchers also found that higher levels of pain were positively associated with larger donations and a more inclusive self-identity.”

DNA Double Takechimeras! and other neat stuff.

Why parents think your partner isn’t good enough“[P]arents tend to give more resources to children whose partners provide less support, and that this leads to a conflict over mate choice…. ‘Parents are equally related to all of their children, whereas children value themselves more than their siblings — so each child wants to get more than their fair share of parental resources.’ This means that the children are willing to settle for a mate who is less caring than their parents would ideally like.”

The Social Life of Genes“Your DNA is not a blueprint. Day by day, week by week, your genes are in a conversation with your surroundings. Your neighbors, your family, your feelings of loneliness: They don’t just get under your skin, they get into the control rooms of your cells. Inside the new social science of genetics.” – h/t you know who you are!

Lifestyle Influences Metabolism via DNA Methylation“An unhealthy lifestyle leaves traces in the DNA. These may have specific effects on metabolism, causing organ damage or disease. Scientists of Helmholtz Zentrum München have now identified 28 DNA alterations associated with metabolic traits. This world-first epigenome-wide association study (EWAS) of modified genes and metabolites has been now published in the journal Human Molecular Genetics.”

A Mathematical Challenge to Obesity“The [obesity] epidemic was caused by the overproduction of food in the United States…. I think the food industry doesn’t want to know it. And ordinary people don’t particularly want to hear this, either. It’s so easy for someone to go out and eat 6,000 calories a day. There’s no magic bullet on this. You simply have to cut calories and be vigilant for the rest of your life.”

Ancient DNA from Neolithic Sweden“[I]t seems that ‘leapfrog’ colonization may be responsible for the spread of agriculture and its associated technologies (such as Megalithism) across Europe. In this model, farmers lept from place to place across the landscape intentionally, preserving their gene pool and largely ignoring the pre-existing foragers of the landscape…. In this respect, the colonization of Europe bears some resemblance to the settlement of the Americas by Europeans: it happened by leaps and bounds, and the early waves of explorers and pioneers may have opened the landscape but did not immediately fill it: this happened later as a result of demographic growth and new waves of migration, with the extant populations being differentially descended — in different proportions — from migrants and natives.” – great post from dienekes.
