Skull Fossil Suggests Simpler Human Lineage“Early, diverse fossils — those currently recognized as coming from distinct species like Homo habilis, Homo erectus and others — may actually represent variation among members of a single, evolving lineage. In other words, just as people look different from one another today, so did early hominids look different from one another, and the dissimilarity of the bones they left behind may have fooled scientists into thinking they came from different species.” see also: Skull of Homo erectus throws story of human evolution into disarray @the guardian. see also john hawks: The new skull from Dmanisi. and greg cochran: All One Species?

speaking of species: Roe Deer × Domestic Sheep“This rather distant cross, which represents a case of interbreeding between separate mammalian families (Cervidae × Bovidae) was reported in the last decade of the 18th century by the Finnish academic Carl Niklas Hellenius (1745-1820), also known as Carl Niklas von Hellens (or af Hellens).” – say what?!

Mysterious Ancient Human Crossed Wallace’s Line“Scientists have proposed that the most recently discovered ancient human relatives — the Denisovans – somehow managed to cross one of the world’s most prominent marine barriers in Indonesia, and later interbred with modern humans moving through the area on the way to Australia and New Guinea.”

Mysterious Minoans Were European, DNA Finds“The Minoans, the builders of Europe’s first advanced civilization, really were European, new research suggests…. ‘They were very similar to Neolithic Europeans and very similar to present day-Cretans,’ residents of the Mediterranean island of Crete.”

People Born With Certain Gene More Likely to Suffer Cognitive Decline After Heart Surgery“Long-term memory loss, difficulty understanding verbal or written communication or impaired ability to pay attention may still occur five years after heart surgery if a patient has a certain gene variation…. This gene was found to be related to a decline in cognitive capabilities compared to those who do not have the variation…. ‘Our study found that if a patient has this gene variation (APOE4), that person is more likely to have cognitive decline five years after surgery.'” – h/t hbd bibliography!

Genetics of eye colours in different rural populations on the Silk Road“[R]egression tree analysis showed that individuals carrying a given combination of haplotypes have a significant probability to show a blue or green/grey iris colour as compared with brown, with a gradient from west to east.” – h/t neuroskeptic!

Scanning for Recent Human Evolution

Evolution is not a one-way road towards complexity“[T]he fact that the highly complex larval muscular bodyplan is so similar in both groups [aplacophorans and chitons] but is only carried over into the adult stage in one of them — the chitons — strongly suggests that the common ancestor of both groups was of similar complexity; thereby implying that the worm-like groups lost these complex traits and became secondarily simplified over evolutionary time.”

What I actually said about genes, IQ and heritability“Rational public debate about genes and intelligence…has proved impossible in Britain and America….”

Heritability estimates and the analysis of variance“In terms that R.A. Fisher might have used, if you plant different strains of wheat in uniformly well ploughed, well mixed, well fertilised soil, then the differences between the different strains will be due to their inherent qualities, and not the vagaries of the soil. On the other hand, if the soil varies considerably then the yields will vary partly because of seed quality, and partly because of soil quality.” – from dr. james thompson.

Intelligence is just another privilege you inherited from mummy and daddy“[I]t is considered bad form for the clever to point out that their advantage is inherited. Yet this has the effect of giving the intellectually privileged the false idea that they have earned their advantage, and eroding the feeling of *noblesse oblige* that the wealthy once felt when they knew their fortune depended on luck. Rather we should regard intelligence as just another privilege you inherit from mummy and daddy…. That would make the world a more, not less, just place.” – from ed west.

US regions exhibit distinct personalities, research reveals“Americans with similar temperaments are so likely to live in the same areas that a map of the country can be divided into regions with distinct personalities, according to new research published by the American Psychological Association. People in the north-central Great Plains and the South tend to be conventional and friendly, those in the Western and Eastern seaboards lean toward being mostly relaxed and creative, while New Englanders and Mid-Atlantic residents are prone to being more temperamental and uninhibited, according to a study published online by APA’s Journal of Personality and Social Psychology.”

Ethics: Taboo genetics and Dangerous work – not very subtle careful or you won’t ever be able to find work in this town again “advice” from the invertebrates @nature (no offense to invertebrates elsewhere). see also: steve hsu, steve sailer, and dr. james thompson. previously: alternate nature poll.

Genomics England“This project will sequence the personal DNA code – known as a genome – of up to 100,000 patients over the next five years.”

Your Genome Is a Post-Apocalyptic Wasteland“Your 25,000 genes reside in a genetic landscape littered with the rubble of ancient and ongoing battles with hordes of viruses, clone armies of genetic parasites, and zombie genes that should be dead but aren’t. Our messy genomic landscape is a dynamic, miniature ecosystem, and scientists are learning how its inhabitants play a big role in human health and disease.”

Morality and the Perspicuity of the True Believers“Consider, for example, a piece Dennis Prager just wrote for National Review Online, packaged as ‘A Response to Richard Dawkins.’ Prager cuts to the chase with the following: ‘If there is no God, the labels “good” and “evil” are merely opinions. They are substitutes for “I like it” and “I don’t like it.” They are not objective realities.’ Thank you, Mr. Prager. I couldn’t have said it better myself.” (^_^) – from helian.

Debate on Evolution of Multicellular Organisms Starts to Gain Focus“Cassandra Extavour and her colleagues, who study the origins of multicellular organisms and the evolution of cooperation, still disagree on the meaning of key concepts such as cooperation, competition and fitness.”

Let the good times roll?“The Frogs have had it rougher than the Canucks.” – from greg cochran. see also: French Canadians: The unexplained genetic diversity from peter frost.

Migration from Sweden to Poland during the Early Bronze Age“‘”Over 3800 years ago, a young male, possibly born in Skåne, made a journey of over 900 kilometers south, to Wroclaw in Poland. He died violently in Wroclaw, killed by Úněticean farmers, possibly due to romance with two local females, who were murdered together with him.”‘” @dienekes’.

Please Pass the Microbes“Once the animal had been processed more or less, I was amazed to see all three [hadza] men take a handful of the partially digested plant material from the recently removed stomach to scrub off the copious amounts of blood that now covered there hands and foreman’s. This was followed by a final ‘cleaning’ with dry grass for good measure. While I was fascinated by the microbe-laden stomach contents being used as hand scrubber – presumably transferring an extraordinary diversity of microbes from the Impala gut to the hands of the Hadza – I was not prepared for what they did next….” – you’ve GOT to read this! (^_^) – h/t john durant!

First physical evidence of why you’re an owl or a lark“They found a reduction in the integrity of night owls’ white matter – brain tissue largely comprised of fatty insulating material that speeds up the transmission of nerve signals – in areas associated with depression. ‘We think this could be caused by the fact that late chronotypes suffer from this permanent jet lag,’ says Rosenberg, although she cautions that further studies are needed to confirm cause and effect.”

Human brain boiled in its skull lasted 4000 years“Seyitömer Höyük – the Bronze Age settlement in western Turkey where this brain was found – is not in the mountains. So how did brain tissue survive in four skeletons dug up there between 2006 and 2011?”

Alien DNA could be ‘recreated’ on earth“Humans will be able to recreate alien life forms and ‘print out’ organisms using the biological equivalent of a 3D printer in the future, a DNA pioneer has predicted.” – craig venter.

Loci number and group difference“This paper shows that the debate about ‘variation within races is bigger than variation between races’ depends largely on the number of loci being analysed, and the assumptions being made about the significance of the revealed differences.” – from dr. james thompson.

Academic fraud in China is getting out of hand“In a few short years, China has metamorphosed from a middling contributor to scientific knowledge into one of the most prolific research entities on the planet. But the country’s meteoric ascent to scientific prominence – widely attributed to a flawed incentive system – has given unintentional rise to a lucrative industry of academic fakery.” – see also: Looks good on paper @the economist.

Poll Shows Major Shift in Identity of U.S. Jews“The first major survey of American Jews in more than 10 years finds a significant rise in those who are not religious, marry outside the faith and are not raising their children Jewish — resulting in rapid assimilation that is sweeping through every branch of Judaism except the Orthodox.”

Electric Shock Therapy May Cut Crime By Stimulating Brain Region For Social Norm Compliance“An original way to reduce crimes rates could lie in regulating neural activity in a person’s front of the brain — right lateral prefrontal cortex. Scientists from the University of Zurich have found a brain mechanism responsible for social norm compliance is separate from the processes that represents a person’s knowledge and beliefs about societal norms. The neurons in this specific brain region may be controlled by electric shock therapy which could potentially stop criminals from breaking the law….” – see also: Brain Stimulation Can Control Compliance with Social Norms“Human beings are utterly dependent on a complex social structure for their survival. Since all behavior is controlled by the brain, human beings may have evolved specialized neural circuits that are responsible for compliance with society’s rules.” h/t михаи́л анисимов!
