The regions of the brain that most strongly differentiate the CEU from the rest are that they have a shrunken occipital cortex (region 2) and a massive dorsolateral prefrontal cortex (region 11). The DLPFC is so small in West Africans you can barely see it in the image.

It was Coon in 1955 who first noticed was has now become doctrine, that it is easier to cool a long, narrow head than a short, broad one. This explains the skull type seen in Africans and Abos and also why the frontal lobes are so small: they produce more heat

Of course a sophisticated buttocks connoisseur takes into size and shape, but as far as sheer bulk nobody on Earth can compare with black Africans, whose asses face so little metabolic competition from their brain.

My original title for this post was going to be “why are Northwest Europeans so nerdy?” and the basic thesis here is that their brain organization is tilting toward autism.

The correlation between total brain volume and IQ is real, but weak (0.3-0.4). But a large brain volume seems to be associated with creative achievement in a way largely independent of IQ.
