Can plants be altruistic? You bet, says new CU-Boulder-led study“‘Embryos with the same mother and father as the endosperm in their seed weighed significantly more than embryos with the same mother but a different father,’ said Diggle, a faculty member in CU-Boulder’s ecology and evolutionary biology department. ‘We found that endosperm that does not share the same father as the embryo does not hand over as much food — it appears to be acting less cooperatively.'” – previously: even plants do it!

How to Survive a Siberian Winter“[T]he study shows how, over the more than 25,000 years that modern humans been lived in Siberia, various peoples have adapted to the region’s cold weather and meaty food sources through selection on multiple genes that control several biological mechanisms.”

National intelligence and personality“‘[T]aken together, Big Five traits and IQs of various cultures statistically explained 70% of a nation’s gross domestic product (GDP) per capita. The most important predictors of economic success were intelligence and extraversion, which proved to be strongly positively related to GDP.'” – from mangan.

New Geology study raises questions about long-held theories of human evolution“While the shift to bipedalism appears to have occurred somewhere between 6 and 4 million years ago, Feakins’ study finds that thick rainforests had already disappeared by that point—replaced by grasslands and seasonally dry forests some time before 12 million years ago.”

Ice Age Lion Man is world’s earliest figurative sculpture – 40,000 years old! – h/t dienekes.

New study sheds light on the origin of the European Jewish population“Elhaik’s findings strongly support the Khazarian Hypothesis, as opposed to the Rhineland Hypothesis, of European Jewish origins.” – h/t jayman!

Some chores linked to less sex“Couples in which the husband did plenty of traditionally male jobs reported more sex than those in which the guy didn’t.” – but you already knew that, didn’t you? (~_^)

It often donates cash to poorer tribes and charities across the country. Since 1996 they have given away $243.5 million…. ‘If it wasn’t for Shakopee, especially during this time when things are tough for loans, tough in this economy — there’s tribes who would be in a very tough situation,’ Ernest Stevens, chair of the National Indian Gaming Association explains. ‘There’s nobody in the gaming industry that I know of that can compare to what Shakopee does.’ In 2010 they were given a Jefferson Award for Public Service.”

  1. Have you ever seen the wikipedia page for Guns Germs & Steel? There is no mention of Diamond missing gene-culture co-evolution or geographic differences favoring different behavioural traits. I’ve added a review by Rushton published in Population & Environment, but it keeps getting deleted.

    This is what I’ve posted in the edit section – someone with some time might want to add something (I recall The 10,000 Year Explosion & ‘Before the Dawn’ are also critical of GGS).

    Psychologist, Professor [[John Phillippe Rushton]], argued that Diamond failed to address evidence of group differences in cognitive ability and the prospect that different environments may favor different behavioural traits.{{cite journal | title=Book Review of J. Diamond: Guns, Germs and Steel | url = http://www.charlesdarwinresearch.org/1999%20Rushton%20review%20of%20Guns%20Germs%20&%20Steel.pdf | author=Rushton, J.P. | journal=Population and Environment | volume=21 | number=1 |date=September 1999}}

    No doubt when I check tomorrow it will have been deleted again :)

  2. @ihtg – “That “Stone Age tribe” article is from 2006…”

    oh, oops! (*^_^*) somebody tweeted it during the week … and i didn’t check the date (obviously). can we call it a “classic link”? (^_^)

  3. re: “New study sheds light on the origin of the European Jewish population –”

    Haven’t read it yet but let’s just say I am highly skeptical based on past reading

  4. @luke – “Haven’t read it yet but let’s just say I am highly skeptical based on past reading”

    past readings of elhaik? or just past reading on the topic in general? (i haven’t read anything from him before … not that i recall anyway.)

  5. @soxy – “Is there less inbreeding in japan than in china”

    see the “mating patterns in asia” series in left-hand column below (almost towards the bottom of the page). i’m actually working on another post on japan at the moment, but it’s not quite finished yet….

  6. “Regarding iq and percapita income, how do you explain china”

    1. China were globally ahead for a very long time.
    2. Europeans overtook them when high density agriculture finally arrived in northern europe – and coincidentally or not at the same time the european marriage model took root – followed by the industrial revolution.
    3. China reluctant to modernize.
    4. China starts to modernize – but falls into communism for 50 years.
    5. ?

    Seems to me at the moment China is looking like it’s going to prove the point by rising to it’s IQ level.

  7. The Jewish ancestry work is fascinating. I was particularly taken by “If there was no mass migration out of Palestine at the 7th century, what happened to the ancient Judeans?” Naughty, naughty!

  8. The idea that IQ is linked directly to national income is terribly ahistorical. North Korea and South Korea probably had about the same IQ in 1953, and the same genetic potential IQ.

    I’d think there’s a better link between national average IQ (or some “smart fraction” stat) and annual increase in per-cap GNP for countries at peace internally with reasonably honest, reasonably capitalist institutions. Russia has bad institutions, therefore underperforms its IQ. Cuba has reasonably honest institutions, and thus does well on many social development indices, but is not capitalist, and therefore doesn’t have economic growth.

    Colombia and Venezuela are similar in ethnic makeup, but Colombia’s government is more honest and the society is more capitalist, so Colombia grows faster than Venezuela’s except when the price of oil rises fast enough. But both have had long histories of poor institutions and/or internal conflict, so they’re poorer than Mexico.

  9. “The idea that IQ is linked directly to national income is terribly ahistorical.”

    That’s not the idea. The idea is there is a link but other things – like communism – can effect it e.g. given the level of resources available in the Antarctic even if the Eskomos were super-bright there would have been a limit to what they could have achieved.

    “what g.w. said above, plus — there’s more to hbd than just iq (although iq is obviously very important). why do some populations manage to have reasonably honest, reasonably non-corrupt institutions, for instance? or be at peace internally?
