Consanguinity and Corruption – “Computing simple, unweighted averages for each country for which studies and surveys have been conducted and subsequently recorded on consang.net and then comparing them to Transparency International’s 2011 Corruptions Perception Index yields a correlation of .44 (p = 0).” – from the awesome epigone! see also steve sailer.
Does cooperation require both reciprocity and alike neighbours? – the answer is yes: “The researchers conclude that human societies can best achieve high levels of cooperative behaviour if their individuals interact repeatedly, and if populations exhibit at least a minor degree of structure.” – in other words, if the members of a society are related to some degree.
An Asian Origin for Human Ancestors? – “Researchers agree that our immediate ancestors, the upright walking apes, arose in Africa. But the discovery of a new primate that lived about 37 million years ago in the ancient swamplands of Myanmar bolsters the idea that the deep primate family tree that gave rise to humans is rooted in Asia. If true, the discovery suggests that the ancestors of all monkeys, apes, and humans—known as the anthropoids—arose in Asia and made the arduous journey to the island continent of Africa almost 40 million years ago.”
Exercise benefits black girls less than whites, study shows – “Physical activity seems a nearly sure way to prevent obesity in white adolescent girls, but does not have the same effect on African American girls, researchers say…. The study … falls in line with research that finds black women oxidize fat more slowly in response to exercise, and that their resting metabolic rates are lower than those of white women.”
[White] Americans’ heads have been growing, scientists say – “Over the last 150 years or so, it appears that skulls got narrower from side to side by about 5 to 7 millimeters, and higher from top to bottom by an average of nearly 10 millimeters, Jantz said. And the overall size of the head has, on average, increased by an amount equivalent to the size of a tennis ball, he said.”
Menstrual huts protect Dogon men from cuckoldry – “Women who practise the traditional Dogon religion, unlike those who are Muslim or Christian, spend five days a month around the time of menstruation in a highly visible ‘menstrual hut’. Strassmann tested paternity in 1700 Dogon father and son pairs and found that those who practised the traditional religion were four times less likely to be raising someone else’s son than those who practised Christianity.”
Lady Liaisons: Does Cheating Give Females an Evolutionary Advantage? – “‘This is one of the most careful and most robust studies to explore whether polyandry is adaptive in females,’ says Tommaso Pizzari, a University of Oxford biologist who was not involved in the research. ‘The answer is: not really.’” – at least not in canadian song sparrows.
