Capturing a Hard-Wired Variability: What Makes Some Identical Twins Noticeably Different?“The current study finds that only one allele is expressed in between 12 and 24 percent of all such pairs encoded by the mouse genome. Further, the selection of expressed alleles varies randomly from cell to cell, and switches frequently between the two options throughout their lives…. ‘We find that for those genes that are not imprinted, roughly one in five alleles is randomly and dynamically expressed only one at a time,’ says Sandberg. ‘And if one allele is being expressed, the other doesn’t know about it. There’s no coordination between two.’”

A Living Time Capsule Shows the Human Mark on Evolution“Scientists have revived shrimp-like animals that have been buried at the bottom of the lake for an estimated 700 years. If this estimate holds up to further testing, they are the oldest animals ever resurrected…. The oldest DNA the scientists obtained from the lake dates back to around the time the Vandals were ransacking Rome. The scientists found that one genetic strain of water fleas dominated at the time — and continued to until the late 1800s. As phosphorus [from fertilizers] flooded the lake, a previously rare strain emerged and took over.”

Evolution Hidden in Plain Sight“One of the hallmarks of *Escherichia coli* as a species is that when there’s oxygen around, it can’t feed on a compound called citrate. But one day a flask turned cloudy with an explosion of *E. coli* that were doing just that. The change was so profound that it may mean these bacteria had evolved into a new species.”

SLC24A5 light skin pigmentation allele origin“‘The distributions of C11 and its parental haplotypes make it most likely that these two last steps occurred between the Middle East and the Indian subcontinent, with the A111T mutation occurring after the split between the ancestors of Europeans and East Asians.’” – @dienekes’.

The brown man with blue eyes“Interestingly, although the Luxembourg man was blue-eyed, he also had brown skin. He lacked the ‘European’ alleles at all three genes involved in the whitening of European skin.” – from peter frost.

Factor Analysis of Population Allele Frequencies as a Simple, Novel Method of Detecting Signals of Recent Polygenic Selection: The Example of Educational Attainment and IQ [pdf] – “Frequencies of 10 SNPs found to be associated with educational attainment in a recent genome-wide association study were obtained from HapMap, 1000 Genomes and ALFRED. Factor analysis showed that they are strongly statistically associated at the population level, and the resulting factor score was highly related to average population IQ (r=0.90). Moreover, allele frequencies were positively correlated with aggregate measures of educational attainment in the population, average IQ, and with two intelligence increasing alleles that had been identified in different studies.” – h/t elijah! see also jayman.

Ancient hunter-gatherers had rotten teeth“Scientists have long thought that tooth decay only became common in humans about 10,000 years ago, when we began farming – and eating starchy crops that fed sugar-loving bacteria on our teeth. But Isabelle De Groote of the Natural History Museum in London, UK, and her colleagues have found widespread tooth decay in hunter-gatherers that lived several thousand years before the origin of agriculture.”

The Liberal Illusion of Uniqueness“[L]iberals underestimate their similarity to other liberals (i.e., display *truly false uniqueness*), whereas moderates and conservatives overestimate their similarity to other moderates and conservatives (i.e., display *truly false consensus*…).” – h/t ben southwood!

Is the dark side of parenting genetic?“In a novel finding, Robert Plomin and colleagues suggest that negative aspects of parenting are more heritable than positive aspects. They call this The Dark Side of parenting. The effect is interesting and subtle: it suggests that whilst parents are generally consistent in their handling of their children, some genetically driven characteristics of their children lead them into more negative parenting styles…. In simple terms, even peaceable parents get irritable with difficult children.” – from dr. james thompson.

Changelings, Infanticide and Northwest European Guilt Culture“To summarize, the changeling lore provides evidence of a NWE guilt culture dating back at least to medieval times, and the practice and attitude towards exposure suggests that ancient Greece had an emerging guilt culture as early as the 400s BC which enabled a similar individualism and intellectual development that we’ve seen in the NWE in recent centuries.” – from staffan.

there was a study published in current biology the other day showing that, unlike “neurotypical” kids, autistic kids don’t overimitate after being shown how to do something. from a popular report @livescience:

“Kids with Autism Don’t Copy ‘Silly’ Actions”

“When imitating the behavior of an adult, children with the developmental disorder autism tend to skip ‘silly,’ unnecessary actions, while those without autism tend to copy everything they see, silly or not, a new study suggests.

“The study involved 31 children with an autism spectrum disorder, and 30 typically developing kids without autism. All the children were asked to watch as an adult showed how to remove a toy (a rubber duck) from a closed Tupperware container. Some of the steps performed were necessary, such as unclipping the lid of the box and taking the lid off, while some were unnecessary, such as tapping the lid twice. The children were then given the container, and asked to get the toy out as fast as they could.

“Kids without autism were much more likely to copy the unnecessary steps, even though the children were not specifically instructed to copy everything the adult did. About 43 to 57 percent of kids without autism copied the unnecessary steps, compared with 22 percent of kids with autism….”

the researcher who conducted the study suggests that: “children with autism do things efficiently rather than socially, whereas typical children do things socially rather than efficiently” [my emphasis].

humans are social creatures. in an extreme sort of way (see: the great civilizations). and our sociality has enabled us to do some fantastic things. but it also makes too many humans thick as planks because most humans really, really, really want to follow and belong to the group. whatever the cost (i.e. even if it means being dumber than a chimp).

and woe to those who don’t play along:

“The End of a Bold Experiment: Big Think and Satoshi Kanazawa”

“Over the past few months, across various social media platforms, and also from the mouths of some of our own bloggers, I have listened to a sustained critique of Kanazawa’s presence on Big Think….

“What I hope results from this experience is what educators call a ‘teachable moment.’ We certainly believe in the value of free speech at Big Think, and give voice to controversial thinkers whose opinions tend to span the political spectrum and often challenge the sacred cows of their respective fields…. However, in providing a platform for dangerous ideas, we also run the risk of overreaching and losing the goodwill of our most dedicated readers. Our commitment is first, and always, to you, and to maintaining your trust…”

…’cause we wouldn’t want you to stop LIKING us and exclude us from the in crowd! heavens, no.

what a bunch of … little thinkers! but that’s all most people are capable of, because most people are social, and social belonging trumps all. like i said over here, it really is us contrarians who require explaining because we are the exceptions to the rule!

jared taylor (quoted by john derbyshire) said recently: “Most people are incapable of holding an unfashionable opinion.”

yup.

(btw, i’m not saying that all contrarians are on the autistic spectrum … but i think a h*ckuva lot of them probably are!)

Their Right StuffThe Grant study has … made the bizarre discovery that subjects’ late-life mental health is strongly associated with the longevity of maternal grandfathers. That indicates a link to both traits somewhere on the X chromosome…. Just as communism, according to an old Hungarian joke, was the long road from capitalism to capitalism, psychiatry now looks like the long road that led from Darwinism to Darwinism.” – heh.

The genetics of stupidity – from greg cochran.

Research suggests that humans are slowly but surely losing intellectual and emotional abilities“With the development of agriculture, came urbanization, which may have weakened the power of selection to weed out mutations leading to intellectual disabilities. Based on calculations of the frequency with which deleterious mutations appear in the human genome and the assumption that 2000 to 5000 genes are required for intellectual ability, Dr. Crabtree estimates that within 3000 years (about 120 generations) we have all sustained two or more mutations harmful to our intellectual or emotional stability.”

How Do You Raise a Prodigy?

Children suffer effects of parents’ divorce into adult life“The children of divorced parents can suffer the effects of the break-up well into their adult life, a report has found.”

Culture: Diverse diagnostics“Perhaps the most dramatic demonstration of this is a study of more than 55,000 children in South Korea, which estimated autism prevalence at 2.64%. That’s more than twice the autism prevalence in the United States estimated by the US Centers of Disease Control and Prevention, and more than 50 times higher than the South Korean government’s figure for autism prevalence of 0.046%. One reason for that higher estimate may be that the researchers screened children in the general population for autism symptoms, rather than recruiting them only from clinics for autism and other developmental disorders.”

Does cloudy weather make you ginger?“Provisional statistics indicate that between two and six per cent of northwest Europeans are redheads, compared to an average of one or two per cent in the world population. But in the UK the numbers are much higher, with 13 per cent of Scots, 10 per cent of the Irish, and six per cent of individuals in England having read hair.”

Hacking the President’s DNA“The U.S. government is surreptitiously collecting the DNA of world leaders, and is reportedly protecting that of Barack Obama…. In the not-too-distant future, they may provide … the basis for the creation of personalized bioweapons that could take down a president and leave no trace.”
