Can You Predict a Monkey’s Social Status by Looking at Its Genes?“Does one’s social stature change how one’s genes are expressed. Yes, concludes a new study that used differences in gene expression to identify a monkey’s social status with around 80 percent accuracy.”

Disliking races may be a personality trait“[I]f a person dislikes one group, he tends to have comparatively cool feelings for all groups, even his own.” – from the inductivist.

More thoughts on genetic load – from greg cochran.

Listen up, parents: For toddlers (and chimps), the majority rules“2-year-olds and chimpanzees are more likely to copy actions when they see them repeated by three of their peers than if they see the same action done by one peer three times.”

Dark coloration and male aggressiveness: Is there a link? – from peter frost.

A gaping hole in the Master’s evolutionary theory – chuck @the occidentalist presents evidence that he says suggests that “there are, at most, small genetic differences, with respect to intelligence, between Black and White adults born, respectively, in Africa and in Europe.”

The Downside of Higher IQ – from dennis mangan, esq.

Genetic Variant Influences Brain Size, Intelligence – from parapundit.

What’s in a surname? New study explores what the evolution of names reveals about China“‘When it comes to surnames the Chinese people are unique. 1.28 billion people share 7,327surnames. In fact the 100 most common names account for 85% of the population,’ said Dr Chen. ‘This means Chinese surnames include more cultural and genetic information than in most other countries….’ The team found the highest levels of surname diversity at the Yangtze River basin, particularly around the middle and lower reaches of the river. The team believes this is due to multiple large migrations throughout Chinese history.”

Fire-free land use in pre-1492 Amazonian savannas“Our combined pollen, phytolith, and charcoal analyses reveal unexpectedly low levels of biomass burning associated with pre-A.D. 1492 savanna raised-field agriculture and a sharp increase in fires following the arrival of Europeans.”

More than 20% of Irish children ‘hear voices’“More than one in five Irish children between 11 and 13 have reported hearing voices, a sign some experts believe is a risk factor in mental illness.”

Study Finds Significant Skull Differences Between Closely Linked Groups“The researchers looked at the skulls of 27 women and 28 men who died in Lisbon, Portugal, between 1880 and 1975. They also evaluated the skulls of 40 women and 39 men who died between 1895 and 1903 in the rural area of Coimbra, just over 120 miles north of Lisbon. The researchers found significant variation between female skulls from Lisbon and those from Coimbra.”

bonus: “Race-Baiting” … and Its Discontents – good one from richard spencer.

bonus bonus: On Dinosaur Time“Less time separates us from Tyrannosaurus rex than separated T. rex from Stegosaurus.” – cool!

bonus bonus bonus: Water, water everywhere – but is it essential to life?“New research by scientists at the University of Bristol has challenged one of the key beliefs in chemistry: that proteins are dependent on water to survive and function.”

  1. I think “The Downside of High IQ” makes a lot of sense based on personal experience (he he) as well as observation of people like this who are way more intelligent than I am (and whom I like a lot btw):

    An entire society of high iq’s would be totally dysfunctional. Look at faculty meetings.

    it would be totally dysfunctional. (^_^)

    i’d like it! but it would still be totally dysfunctional. (~_^)

  3. OT, but an interesting quote: “We already know there are more than half a million DNA base pair differences that contribute to general intelligence differences between people,”

    Half a million? I knew it was a lot but 500,000?

    Anyway I like Geoffrey Miller’s expansion of Darwin’s ideas about sexual selection. It’s half the game!

  4. @luke – “Half a million? I knew it was a lot but 500,000?”

    cool! (^_^)

    but, we do have … what? … ca. 3 billion base pairs in our dna, so 500,000 is 1/6000th of the total. not really too surprising when you think of how important intelligence is to being successful at being human (as compared to being, say, a successful squirrel monkey).
