Is Beauty in the Face of the Beholder?“We concluded that individuals, if given the opportunity, seek to promote ‘positive assortment’ for Self’s phenotype, especially when the level of similarity approaches an optimal point that is similar to Self without causing a conscious acknowledgment of the similarity.” – on assortative mating, via race/history/evolution notes.

3.4-7.9% Neandertal admixture in Eurasia?“‘Our analysis allows us — for the first time — to formally reject a history of ancestral population structure and instead reveals strong support for admixture from Neandertals into Eurasian populations at a higher rate (3.4%-7.9%) than suggested previously.'” – @dienekes’.

and speaking of neanderthals: Neanderthals made leather-working tools like those in use today.

Genetics and alcoholism“Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person’s risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2.”

Sense of smell has a genetic flavour“Richard Newcomb of the New Zealand Institute for Plant and Food Research (IPFR) in Auckland and his colleagues have found the most convincing evidence yet of a genetic basis to the differences in people’s odour perception.” – via hbd bibliography.

Immigration and inbreeding“[T]he more inbred a country is, the more restrictive the attitudes of its population are on the issues of immigration and citizenship. Conversely, the more outbred a country is, the more its inhabitants tend toward unrestricted open borders.” – from the awesome epigone.

Religious people are less intelligent than atheists, analysis of over 63 scientific studies stretching back over decades concludes“Study found ‘a reliable negative relation between intelligence and religiosity’ in 53 out of 63 studies.” – via nelson.

Jason Richwine and some Hispanic data“In summary, if one uses scholastic data as a measure of ability, then there was some significant narrowing of the White/Hispanic gap in the early 1980’s, but that reduced gap has persisted thereafter. This finding discomforts those who predicted that the gap would never change, and those who said it was closing fast and would shortly disappear. Both are wrong, are partially right.” – from dr. james thompson.

Population Structure of Hispanics in the United States: The Multi-Ethnic Study of Atherosclerosis“By comparing genetic ancestry of MESA Hispanic participants to reference samples representing worldwide diversity, we show major differences in ancestry of MESA Hispanics reflecting their Caucasian, African, and Native American origins, with finer differences corresponding to North-South geographic origins that separate MESA Mexican versus Central/South American samples. Based on our analysis, we define four subgroups of the MESA Hispanic cohort that show close agreement with the following self-identified regions of origin: Dominican/Cuban, Mexican, Central/South American, and Puerto Rican.” – via nelson.

Personality May Predict If You Like Spicy Foods“Those in the group who fell below the mean AISS [adverse to risk taking] rapidly disliked the meal as the burn increased. People who were above the mean AISS [prone to risk taking] had a consistently high liking of the meal even as the burn increased. Those in the mean group liked the meal less as the burn increased, but not nearly as rapidly as those below the mean.”

Genetic Variants Linked to Educational Attainment“A multi-national team of researchers has identified genetic markers that predict educational attainment by pooling data from more than 125,000 individuals in the United States, Australia, and 13 western European countries…. Combining the two million examined SNPs, the SSGAC researchers were able to explain about 2 percent of the variation in educational attainment across individuals, and anticipate that this figure will rise as larger samples become available.” – h/t friendly e-mailer! (^_^) – see also steve hsu on this: First GWAS hits for cognitive ability (thanks, grey!). in particular, check out steve’s graph. and john derbyshire for more on looking for iq-related genes via gwas studies. see also dr. james thompson: Educational attainment, intelligence, and the relentless cracking of the genetic code.

GSS on Haidt’s Moral Foundations theory“The GSS results largely support Haidt’s divisions, with liberals putting greater emphasis on liberty/oppression and especially care/harm, just as he found to be the case. Conservatives, on the other hand, are more concerned with fairness/cheating, authority/subversion, sanctity/degradation, and loyalty/subversion than liberals are.” – from the awesome epigone!

Homosexuality is natural. Fine. But what if homophobia is natural, too?

The Ugly Truth About Obesity“So yes, the obese group is not unlike its negative stereotypes. Of the, ‘lazy’, ‘sloppy’, ‘less competent’, ‘lacking in self-discipline’, ‘disagreeable’, ‘less conscientious’, ‘poor role models’, ‘unintelligent’, ‘unsuccessful’, ‘weak-willed’, ‘unpleasant’, ‘overindulgent’, it seems ‘disagreeable’ and ‘unpleasant’ are the only clear misses. This is not to hate on the obese, but to call a spade a spade.” – from staffan!

Breeding the Nutrition Out of Our Food“Studies published within the past 15 years show that much of our produce is relatively low in phytonutrients, which are the compounds with the potential to reduce the risk of four of our modern scourges: cancer, cardiovascular disease, diabetes and dementia. The loss of these beneficial nutrients did not begin 50 or 100 years ago, as many assume. Unwittingly, we have been stripping phytonutrients from our diet since we stopped foraging for wild plants some 10,000 years ago and became farmers.”

Europeans did not inherit pale skin from Neanderthals“By analysing the genomes of 50 people with European ancestry and 70 people with sub-Saharan African ancestry, Beleza’s team could estimate when the three genes – and pale skin – first became widespread in European populations. The result suggested that the three genes associated with paler skin swept through the European population only 11,000 to 19,000 years ago.”

Is castration the secret to a long life?“Scientists believe they may have discovered the secret to longevity for men – but it comes at a painfully high price.” – yikes!

Inside the Cold, Calculating Libertarian Mind“[W]hen libertarians reacted to moral dilemmas and in other tests, they displayed less emotion, less empathy and less disgust than either conservatives or liberals. They appeared to use ‘cold’ calculation to reach utilitarian conclusions about whether (for instance) to save lives by sacrificing fewer lives. They reached correct, rather than intuitive, answers to math and logic problems, and they enjoyed ‘effortful and thoughtful cognitive tasks’ more than others do. The researchers found that libertarians had the most ‘masculine’ psychological profile, while liberals had the most feminine….”
