Stone Age skull from Kenya reveals astonishing human diversity“A partial human skull found at a site in Kenya suggests early humans living in Africa were incredibly diverse. The 22,000-year-old skull is not a new species and is clearly that of an anatomically modern human, but is markedly different from similar finds from Africa and Europe from the same time, the researchers said…. [T]he new findings suggest that during this early period of human history, Africa may have supported even greater human diversity, with small, offshoot lineages that no longer exist today….”

Division of labor by sex and age in Neandertals: an approach through the study of activity-related dental wear“The study reveals that all individuals have cultural striations, but those detected on the adult females are longer than the striations found in adult males. Regarding the distribution of dental chipping, the prevalence of this trait is higher in the maxillary dentition of males whereas females have the majority of dental chipping on their mandibular teeth. T he differences detected on the overall activity-related dental wear pattern denote a difference or a division of labor by age and sex in Neandertals while using the mouth as a third hand, i.e., in activities other than the provisioning of food, and provide new evidence for the lifestyle of this Pleistocene fossil human species.” – h/t paleogenomics!

Y chromosomes and Catalan surnames“‘By genotyping 17 Y-STRs and 68 SNPs in ~2500 male samples that each carried one of the 50 selected Catalan surnames, we could determine sets of descendants of a common ancestor, the population of origin of the common ancestor, and the date when such a common ancestor lived. Haplotype diversity was positively correlated with surname frequency, that is, rarer surnames showed the strongest signals of coancestry. Introgression rates of Y chromosomes into a surname by non-paternity, adoption, and transmission of the maternal surname were estimated at 1.5−2.6% per generation, with some local variation. Average ages for the founders of the surnames were estimated at ~500 years, suggesting a delay between the origin of surnames (twelfth and thirteenth centuries) and the systematization of their paternal transmission. We have found that, in general, a foreign etymology for a surname does not often result in a non-indigenous origin of surname founders; however, bearers of some surnames with an Arabic etymology show an excess of North African haplotypes.'” – @dienekes’.

Low IQ ups risk of heavy drinking among men“The researchers analysed data collected from 49,321 Swedish males born during 1949 to 1951 and who were conscripted for Swedish military service from 1969 to 1971. IQ results were available from tests performed at conscription, and questionnaires also given at conscription provided data on total alcohol intake (consumed grams of alcohol/week) and pattern of drinking, as well as medical, childhood and adolescent conditions, and tobacco use. Adjustments were made for socio-economic position as a child, psychiatric symptoms and emotional stability and the father’s alcohol habits. ‘We found that lower results on IQ tests in Swedish adolescent men are associated with a higher consumption of alcohol, measured in both terms of total intake and binge drinking,’ Sjolund said.” h/t ruta akula!

Islam Is Not a Religion of the Book“By this, I mean that as a whole humans are prone to accepting the primary causal role of reflective cognition, of beliefs avowed and rationales offered. We are confident in our conscious self control, despite a robust body of cognitive psychology which implies that much of our cognition is not under the control or constraint of rational faculties. This problem is particularly extreme among intellectuals, the very class which also attempts to understand human phenomena. Through the simple process of introspection and extrapolation intellectuals tend to reduce human action to the outcome of ratiocination, inference from eternal axioms. This is wholly inadequate to a phenomenon as complex as religion.” – from razib.

Old India’s Village of Warriors Becomes Birthplace of Bouncers“Look closely and it becomes clear that the bouncers are all of a single physical type, their chests and biceps built like the front bumper of a sport utility vehicle. If they look like cousins, it is because they are. A startling number of them share a family name, Tanwar, and when the nightclubs close many will return to the same nearby village, a place where women walk down dusty lanes with their faces obscured by a cloth, balancing stacks of dried cow dung on their heads, much as their ancestors did three centuries ago…. The musclemen from the village of Fatehpur Beri are the descendants of the original inhabitants of the city, a genetic line that fortified itself over the course of centuries as they defended their village against waves of invaders on their way to the seat of empire. The sons and grandsons of cow and goat herders, they were born in an outpost surrounded on all sides by croplands. As Fatehpur Beri was swallowed by the expanding city, its spartan strongmen continued to train in the traditional way, stripping down to loincloths and wrestling in a circle of mud. But they were forced to look for a new line of work. ‘There is an element of the warrior in the Tanwars,’ said Ankur Tanwar, who opened the village’s first gym about a decade ago. ‘We fought with the Muslim invaders. We fought with the Britishers.'”

‘Rare’ Gene Common in African Descendants, May Contribute to Heart Disease“Researchers at Weill Cornell Medical College have found that a genetic variation that is linked to increased levels of triglycerides — fats in the blood associated with disorders such as heart disease, type 2 diabetes, obesity and stroke — is far more common than previously believed and disproportionally affects people of African ancestry…. The finding offers a clue as to why Africans and people of African descent have an increased risk of cardiovascular disease and type 2 diabetes compared to many other populations, says the study’s senior author, Dr. Ronald Crystal, chairman of genetic medicine at Weill Cornell. African Americans with the variant had, on average, 52 percent higher triglyceride levels compared with blacks in the study who did not have the variant…. The gene variant the scientists studied is a single point mutation — a replacement of one of DNA segment with another — in the ApoE gene, which carries fats and other molecules through the blood.” – h/t hbd bibliography!

A gene mutation for excessive alcohol drinking found“UK researchers have discovered a gene that regulates alcohol consumption and when faulty can cause excessive drinking…. [M]ice with a genetic mutation to the gene Gabrb1 overwhelmingly preferred drinking alcohol over water, choosing to consume almost 85% of their daily fluid as drinks containing alcohol…. Dr Quentin Anstee, Consultant Hepatologist at Newcastle University, joint lead author said: ‘It’s amazing to think that a small change in the code for just one gene can have such profound effects on complex behaviours like alcohol consumption.’ – see also Firewater from greg cochran.

Predicting Human Body Height from DNA“Predicting tall stature from these 180 DNA variants resulted in an accuracy of 0.75 on a scale from 0.5 (meaning random prediction) to 1.0 (completely accurate prediction). ‘Although the achieved DNA-based prediction accuracy for tall stature is still somewhat lower than we previously established for eye color, hair color and age,’ said Kayser, ‘I expect that upcoming new knowledge on height genetics will further increase the accuracy in predicting tall stature, and eventually the full range of body height, from DNA.'”

Study Connects Dots Between Genes, Human Behavior“The team studied individuals with a rare disorder known as Williams syndrome. By measuring neural activity in the brain associated with the distinct language skills and facial recognition abilities that are typical of the syndrome, they showed that Williams is due not to a single gene but to distinct subsets of genes, hinting that the syndrome is more complex than originally thought.”

Different Gene Expression in Male, Female Brains May Help Explain Brain Disorder Differences“UCL scientists have shown that there are widespread differences in how genes, the basic building blocks of the human body, are expressed in men and women’s brains. Based on post-mortem adult human brain and spinal cord samples from over 100 individuals, scientists at the UCL Institute of Neurology were able to study the expression of every gene in 12 brain regions…. They found that the way that the genes are expressed in the brains of men and women were different in all major brain regions and these differences involved 2.5% of all the genes expressed in the brain.” – h/t heartiste!

freaky polygamy

here’s a fundamentalist moromon mormon(!) guy with his three wives (not that there’s anything wrong with that! – apart from the fact that there must now be two fundamentalist mormon guys without wives…) and 18 of their 24 collective kids.

the unusual thing (i guess) is: two of the wives are sisters — twin sisters! — and the third wife is their cousin. mamma mia!

i got to thinking about the kids (who all look cute as buttons! – except for the one guy in the back who’s going through some severe teen angst by the look of it). the kids of the two sisters are both half-siblings (’cause they have the same dad but different moms) AND first-cousins (’cause their moms are sisters) to one another.

got that? ok.

the kids of the cousin are half-siblings to the twin sisters’ kids (’cause they all share the same dad but different moms) AND they’re first-cousins-once-removed (’cause their moms are first cousins) to them.

BUUUUUUUT … the two sisters are twin sisters, so they must share virtually identical genomes, right? so that must mean that their kids are genetically similar to one another as though they were full siblings even though they have two different moms.

whoa.
