Baffling 400,000-Year-Old Clue to Human Origins – denisovans in SPAIN 400,000 years ago! cool. – see also 400 thousand year old human mtDNA from Sima de los Huesos from dienekes. – and see also Hominin DNA baffles experts.

Snakes outpacing other vertebrates in race to evolve“The first two full snake genomes to be sequenced – belonging to the Burmese python and the king cobra – show that they have one of the fastest rates of genetic evolution among vertebrates.”

Earliest Stone-Tipped Projectiles from the Ethiopian Rift Date to >279,000 Years Ago“Projectile weapons (i.e. those delivered from a distance) enhanced prehistoric hunting efficiency by enabling higher impact delivery and hunting of a broader range of animals while reducing confrontations with dangerous prey species. Projectiles therefore provided a significant advantage over thrusting spears…. Direct evidence for such projectiles is thus far unknown from >80,000 years ago. Data from velocity-dependent microfracture features, diagnostic damage patterns, and artifact shape reported here indicate that pointed stone artifacts from Ethiopia were used as projectile weapons (in the form of hafted javelin tips) as early as >279,000 years ago.” – see also Oldest Javelins Predate Modern Humans, Raise Questions on Evolution – h/t naturalismo! – and see also Stone tipped spears used 500,000 years ago – thrusting ones, tho.

Discovery of partial skeleton suggests ruggedly built, tree-climbing human ancestor“Massive arm bones provide insight into how ‘robust’ P. boisei species, found by Leakey, adapted in Africa.”

Iberian Neolithic farmer DNA“‘The Neolithic Portalón individual is genetically most similar to southern Europeans, similar to a Scandinavian Neolithic farmer and the Tyrolean Iceman. In contrast, the Neolithic Portalón individual displays little affinity to two Mesolithic samples from the near-by area, La Brana, demonstrating a distinct change in population history between 7,000 and 4,000 years ago for the northern Iberian Peninsula.'” – @dienekes’.

How genetics are rewriting the history of the Caribbean“The Spanish who arrived in the New World were de facto polygamists who killed or enslaved the local men and impregnated the women.” – from razib.

Male and female brains wired differently, scans reveal“Maps of neural circuitry show women’s brains are suited to social skills and memory, men’s perception and co-ordination…. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, in contrast to men’s brains, where the connections were typically stronger between the front and back regions.” – see also Sex differences in the structural connectome of the human brain. – and see also Stop the Presses! from malcolm pollack. (^_^)

Promiscuity Is Pragmatic“Why women and other female primates seek out multiple partners…. [T]here are two environmental contexts where women commonly choose multiple partners. The first is where women have more material support from their kin or economic independence from men more generally. This may explain why multiple mating is most common among small-scale matrilocal societies (in which women remain in their home village after marriage), such as the partible paternity societies of South America or the Mosuo of China. It may also explain why female infidelity has increased in Western societies as women have gained greater political and economic independence…. The second environmental context Scelza identified is where the sex ratio is female-biased (indicating a scarcity of men) or there is a high level of male unemployment (indicating a scarcity of men who can provide support).” – one for the gameboyz.

Our IQs Are Climbing, But We’re Not Getting Smarter – re. woodley and armstrong paper.

Academic experts criticise Boris Johnson IQ claims“Dr James Thompson, senior lecturer in psychology at University College London, said Boris had been ‘inelegant’ in his choice of words. Thompson, co-author of Cognitive Capitalism, said: ‘What Boris Johnson has done is inelegantly describe things which in fact do seem to be true: intelligence, however you assess it, is predictive. It’s predicative of income, life span and of occupational status. People are different and have different futures and intelligence seems to be an important part of that.’ He said studies showed there seemed to be a correlation between ‘being bright in youth and doing well in life later’. Asked if inequality was inevitable, he said: ‘In one way that is true. There’s two things, one is that some people are brighter than others and can do more complicated work and that more complicated work is generally more valued.’ However, he added that how much people should be paid was a decision for society. Professor Richard Lynn, co-author of IQ and the Wealth of Nations, said that the association between IQ and income was ‘only modest’. ‘That is because some high IQ people go into jobs that don’t have particularly high earnings like university professors, schoolteachers or social workers. Some professions attract very high IQ people but they don’t have very high earnings,’ he said. ‘You could say that the IQ is only one determinant of high earnings, the others are ambition and motivation and the third one is luck.'” – h/t holtz!

The 7 tribes of intellect – from dr. james thompson.

Morality and the State“In general, ‘virtuous’ states – those free of corruption, that do not cheat or steal from their citizens, and that are effective in enforcing laws that are perceived as just – are more effective at promoting the common weal than their opposites. Heraclitus’ dictum that ‘character is destiny’ likely applies to states as well as individuals. I personally think that states are far more likely to be ‘virtuous’ in that sense if their powers are carefully circumscribed and limited.”

Could absence of a father permanently rewire the brain? – from mr. mangan, esq.

Investigation reveals black market in China for research paper authoring“The journal Science has uncovered, via investigation, a thriving black market in science paper authoring—people are paying to have their names added to papers that have been written to describe research efforts…. All in all, the investigative team contacted 27 agencies involved in helping researchers get their work published—only five of them refused an offer to pay for adding a name to a research paper.”

They have only one land to call home…unlike the many ‘refugees’ who regularly visit their own homelands. Once the Danes lose majority status in their country, they’ll be like the Copts of Egypt and other minorities in this world. They’ll have to live by their wits, trying to balance off one potential enemy against another.” – hear, hear! – from peter frost.

Migration Hurts the Homeland“The migration that research shows is unambiguously beneficial is the kind in which young people travel to democracies like America for higher education and then go home. Not only do these young people bring back valuable skills directly learned in the classroom; they bring back political and social attitudes that they have assimilated from their classmates. Their skills raise the productivity of the unskilled majority, and their attitudes accelerate democratization…. Many on the left, for their part, don’t like to recognize that we’re taking away fairy godmothers. They prefer to believe that they’re helping poor people flee difficult situations at home. But we might be feeding a vicious circle, in which home gets worse precisely because the fairy godmothers leave. Humanitarians become caught up trying to help individuals, and therefore miss the larger implications: There are poor people, and there are poor societies. An open door for the talented would help Facebook’s bottom line, but not the bottom billion. – h/t michael story!

    Cochran’s post on Ancestral Journeys was interesting. I didn’t know there was such taboo against the idea that violence and invasions *weren’t* invented recently. I was wondering if you have posted anything on historical human violence before.

    Which is not to say that enslaving and impregnating are mutually exclusive. They must have settled down with the women. How did they treat their children? There are good memoirs and reports from those periods, what do they say?

  5. “Professor Richard Lynn, co-author of IQ and the Wealth of Nations, said that the association between IQ and income was ‘only modest’.

    I think the correlation coefficient is something like .40 which means that it will tell you a lot more about large groups than individuals. This is an important point because it means that IQ not destiny. Also we (I) need to keep in mind that “g” is the underlying correlate for various kinds of mental abilities (or, rather, aptitudes). It is not the aptitudes themselves, let alone the abilities. Nobody ever told me my IQ and I’m glad they didn’t. I would have over-estimated its significance I’m sure — as do most people who are much above average. There, you have the wisdom of senility.

    oh, yeah. modern archaeology has been completely lost in space (read: politically correct). that’s why we’ve had all this nonsense like there wasn’t much of an anglo-saxon invasion/takeover in england — just a handful of anglo-saxons arrived and they were really nice to everybody. yeah, right.

    @420blazeitfgt – “I was wondering if you have posted anything on historical human violence before.”

    i haven’t posted anything about invasions, but i have had a couple of posts about the reduction of violence (homicides) in northwest europe which began in the middle ages. see here and here for example.

    I don‘t have a point, I just wanted to give the term the exclamation point it deserves, if only for the poetry of it.

    The promiscuity article and mention of infidelity made me think of another evolutionary reason women might cheat. If you are having sex with one man over a period of time and yet you are not getting pregnant, from an evolutionary point of view it might make sense to try another man, in case you are wasting your chance to have offspring on a man who is infertile. So it would make sense for evolution to have built into women a desire to cheat that increases the longer they are with one man without getting pregnant. Of course this would be true only if male infertility was a significant problem. I don‘t know if this is the case.

  13. Frau Katze,

    There is a Guardian “comment is free” piece with the subheading (if that’s the right term):

    “Why do studies reinforce stereotypes about the male versus female brain, when the truth is that we are not so very different?”

    Funniest thing (just the subheading not the piece) I’ve read all week. How anyone could have written it in earnest I’ll never know.

    Reply

  14. It took only moments for Wired to post a story about how ‘men and womens brains are not in fact different’, though it seems they’ve changed the title of the article to a less strong statement. The commenters were eating the article alive.

    I see this happen every time these articles come out as the girly men and manly women get together and attack largely because they haven’t accepted that they are outliers. I think it feels to them like they’re being called not a real man or not a real woman because they don’t conform to the majority. I’d argue the solution might be a definition of manliness that includes the creative, emotional, and literary guys (I am one of these by the way) but acknowledges them as less common. Likewise it would be nice to see a definition of womanhood that includes hard core analytical thinkers who lack just as much empathy as some males (My mother is like this) but again acknowledges that they too are rare.

    What we’re seeing with feminism attacking ‘stereotypes’ is, I believe, a manifestation of the ‘battle within the sexes’ (normal men vs girly men and normal women vs manly women) an essay I’ve been contemplating writing for sometime but I don’t know if anyone would care to read it.

  16. ‘You could say that the IQ is only one determinant of high earnings, the others are ambition and motivation and the third one is luck.’”

    Mental and physical health are others, for individuals, relatively independent of intelligence. I suppose you could call that luck, which is rather a “I can’t be bothered to talk about the specifics of other factors” catchall, with the odd notion that how high IQ and how ambitious and motivated a person is are somehow not factors which are due to their (genetic or environmental) luck.

    IQ-wealth correlations really just say “Within the current economic structure, higher / lower IQ people tend to have more wealth”, not that it is necessarily logically the case that this must be so (as globalistic inequality celebrant Johnson would do).

    Male and female brains wired differently, scans reveal

    Connectivity differences are interesting. It’ll be interesting to see if people who flagged sex atypical have atypical connectivity or have the same connectivity with atypical processing within the same connectivity, such as stronger or more efficient signalling in a sex atypical fashion, or atypical for their gender but not necessarily very typical for the “other gender”.

    For instance, where would a person with high connectivity within both hemispheres of their parietal cortex, but not elsewhere in the brain, fall in a schema like this? That person might, functionally, be odd, but not particularly in a male or female type way (although they might feel somewhat alienated from other men or women).

    I do wonder if some of this is a kind of artifact of brain shape differences between men and women – brain shape in men tends to be more long and narrow than women – at least in Europeans, Asians may show a slightly different pattern (search “Hemispheric Shape of European and Japanese Brains” for further information) – so if the brain mass gets strung out more linearly, perhaps for reasons dependent on skeletal shape and the cranial base, then connectivity my have to increase along this axis to maintain efficient signalling.

    Similarly, more modular male brains might be a consequence of size increases – the further a signal has to go, the bigger the loss of processing speed by distance, and size increases add to this. So the pressure is on for more local (and “modular”) processing within regions.

    riiiiight. *facepalm*

    you’ve probably noticed that i almost never — in fact, pretty much don’t — write about the hbd differences between men and women. that’s ’cause, imho, the differences between men and women are so GLARINGLY OBVIOUS that i find them almost boring to discuss.

    would definitely be cool to work out what, exactly, all the biological/physiological/etc. differences actually are, but to not notice that men and women are different is just the height of stooopidity, afaiac.

    this is absolutely spot on!

    the tagline here on the blog — “the exception that proves the rule” — is slightly tongue-in-cheek, but i mean it seriously, too. i’ve known for a very (very) long time that i was “odd” compared to most of the females that are out there — definitely since i was a teenager, but even as a kid — i wanted a train set and LEGOOOOOOHHHHHHs, NOT dolls and tea sets. (ok, i did like barbie dolls for a time, but mostly ’cause i liked all the clothes. in that way i am a girl — pretty dresses=niiiiice! (~_^) )

    when the larry summers brouhaha happened, i kept giggling to myself that all of the academic women who were objecting to what he said about women and math were such a-typical women! the whole lot of them. and, like you, i thought at the time, if they’d just realize that they were the ones who were a bit odd — outliers.

    @sisyphean – “I’d argue the solution might be a definition of manliness that includes the creative, emotional, and literary guys (I am one of these by the way) but acknowledges them as less common. Likewise it would be nice to see a definition of womanhood that includes hard core analytical thinkers who lack just as much empathy as some males (My mother is like this) but again acknowledges that they too are rare.”

    i’d be down with that! i think a lot of the upset comes when people say “women are…” whatever or “men are…” whatever, when really what they mean is that “women *on average* are…”, “men *on average* are….”

    In some of the early kibbutzim in Israel were so into gender equality that there was only one size and style of clothing for all members, male and female alike. You picked up your week’s allotment in the communal laundry room. Over time the membership were disturbed when they noticed a gradual drift toward a conventional gender division of labor throughout the commune. Even worse the same two or three (or five or six or whatever) individuals (not all men necessarily) kept ending up in charge of just about every organized effort undertaken. It was like the iron law of oligarchy or something rearing its ugly head. Today in Israel I read that thirteen powerful families more or less dominate the economy. Some patterns emerge no matter how smart you are.
