Study documents early puberty onset in boys“Pediatricians recorded the earliest stage of puberty as occurring in non-Hispanic white boys at age 10.14 years; in non-Hispanic African-American boy at age 9.14 years, and in Hispanic boys at age 10.4. Overall, African-American boys were more likely to start puberty earlier than white or Hispanic boys.”

When Europeans turned white” White European skin evolved relatively fast during the last ice age, specifically from 19,000 to 11,000 years ago…. These color traits—white skin and a diverse palette of hair and eye colors— are not adaptations to a cooler, less sunny climate. They are adaptations by early European women to intense mate competition, specifically a shortage of potential mates due to a low polygyny rate and a high death rate among young men.” — from peter frost.

  1. 1. The cuteness of the spider monkey somehow becomes very sinister when you notice the black nail polish and witchy smile of the handler, and subsequently notice that it is using its left monkey hand to suck out the photographers soul. A baby spider monkey would be the most badass sorcerer familiar *ever*.

    2. Also, Frosts article is at the same time good, yet disturbingly obvious seeming – until you realize that it’s not obvious for so many people. Sigh.

    3. The Swedish military has done studies correlating resilience to PTSD strongly with IQ, over titanic sample sizes (many tens of thousands). Of course, the genetic basis of IQ meshes with the genetic basis of PTSD resilience… there’s likely a big genetic overlap.

    note to self: find out how to rent sinister looking baby spider monkey to go along with this year’s halloween costume….

  3. The Wall Street Journal also reported on the early maturation study – and science reporter Melina Beck also reported on the scientists’ puzzling over why blacks mature earlier than whites with a straight face. As if previous studies have not shown the same thing dozens of times over. But the best part is the comment section, where WSJ readers actually wonder if it’s because whites can afford to drink organic milk. Seriously. This is what they think causes later maturation – access to organic milk.

    What Is War Good for?
    A: Limiting your breeding population to 20-150 members.

    1. Population exceeds 20-150 limit.
    2. Fission off a smaller sub-group.
    3. Launch attacks against sub-group until it is killed off.
    4. Population of group is now within 20-150 limit.
    5. Increase in numbers.
    6. GOTO 1

    Seven adult males and three mothers and their offspring began spending longer and longer periods of time in the southern part of the range

    these chimpanzees had formed an entirely new and separate community, which became known as Kahama.

    However, a series of deadly brutal attacks perpetrated by the powerful Kasekela community on individuals of the Kahama community followed. It was known as the Four-Year War at Gombe.

    Possibly related to maintaining an ideal population size:

    Role of inbreeding depression and purging in captive
    breeding and restoration programmes

    Purging mildly deleterious recessives by drift
    would be ineffective at very large or small populations;
    highest effectiveness was observed at populations contain-
    ing several hundred individuals in the examples provided
    by Glémin (2003).

  6. @ When Europeans turned white –

    Incidentally Chinese beauties are also notable for their white, white skin. More like parchment, fewer blemishes than the European on average. At least that is my impression.

    Yes. In other news:

  8. You are welcome HBD Chick! The WSJ comment section is always good for a laugh. Unfortunately, it’s also a good indicator of where we stand as a nation. xxx

  9. re: sexual selection

    My impression is that high-status males have been selecting the most beautiful females (often more than one) for the last several thousand years with the exception of sub-Saharan Africa, where it’s been the other way around. If you accept the idea of rapid evolution, that would explain a few things.

    This question obviously requires LOTS more research. I wonder if I can get a grant…

    just make sure to mention the implications of global warming on your study (more incidences of sunburnt women in the future?) — that oughta do it! (~_^)

    not sure. =/

    somewhere in the account setting of wordpress or gravatar i’m guessing. -?- or maybe it’s something that got picked up from disqus (if you have an account there)? or even facebook?
