another sunday linkfest on a thursday. what IS the world coming to?! =/
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.”
Researchers find first evidence of primates regularly sleeping in caves – ring-tailed lemurs!
Ancestral Journeys – greg cochran reviews a book! – just like he
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!
A very mild form of Sapir-Whorf – from elijah.
Are You A Workaholic? Blame Your Parents – “A new study from the University of Michigan finds that how we feel about work depends on how our parents feel about work.” – especially your father, apparently. hmmmm.

bonus: Fruit flies with better sex lives live longer – “Male fruit flies that perceived sexual pheromones of their female counterparts – without the opportunity to mate – experienced rapid decreases in fat stores, resistance to starvation and more stress. The sexually frustrated flies lived shorter lives.” – bzz. =(
