The next thing I noticed in my Dopaquest was that about a week in my hair had become as thick as it was when was a teenager and then it kept getting even thicker. My eyebrows also became thick and conspicuously dark.

Blacks have higher pulses of growth hormone than whites do and much of what makes their appearance distinctive is similar to changes seen in acromegaly: thick hair and dry skin, loud, deep voices, large hands.

In all of 1835 Europe I would be surprised if there were 1,000 part black individuals integrated into society, but from this miniscule group emerged the 1/4th black Alexandre Dumas and the 1/8th Alexander Pushkin.

Outside of Africa, the place where this physical type is seen at the greatest frequency is among sun baked Indians, who in their natural environments enjoy very low schizophrenia rates.

The distinctive Indian pattern of extremely fast, extremely quarrelsome speech likely results from a combination of African like dopaminergic tone while possessing a normal or even superior group IQ.

But the group that stands apart from their close neighbors in all these ways the most starkly are the Irish. However, they’re very different from the all populations mentioned so far: way up north, little sunlight, not much fish consumption now or in the past.

The primary clue to uncovering what’s happened is that the Irish represent a European extreme in two other ways: unexposed skin that is lighter than any European people, even Scandinavians, and a continent high frequency of hemochromatosis (iron overload).

Both of these distinctive features act to preserve bone health under conditions of very high rainfall and little sunlight. Those with light skin are able to produce more Vitamin D after exposure to sunlight than the competition: https://www.researchgate.net/profile/Etienne_Cavalier/publication/258054176_Skin_Color_Is_Relevant_to_Vitamin_D_Synthesis/links/544a06e60cf2ea65413426e5/Skin-Color-Is-Relevant-to-Vitamin-D-Synthesis.pdf …

I think Ireland and Iceland, both rain soaked and sunless, may be the only two places on earth where alcoholism was selected for because consumption linearly increases ferritin stores in blood. An old farmer may have found it easier to get a hold of booze than animal protein.

Icelanders don’t have problem drinking rates higher than other Europeans, but this is confounded by the fact that they enforced prohibition until NINETEEN EIGHTY-NINE. I don’t think they were just being sticklers: there is something funny going on here.

But circling back to the main point: In Coon’s The Races of Europe I believe the Irish are the only group singled out for the thickness of their bones and part of the mechanism has probably been a ruthless selection for both light skin and high baseline levels of Vitamin D.

D helps protect Irishmen against rickets and inflammatory diseases, but an expected benefit of the selection was this it provided them with a stronger immunity to schizophrenia than any other North European people. Psychotism is a plus if your body can handle it and they could.

About ¼ of Mormons have Scandinavian surnames, principally Danish and Norwegian, and I think the low hanging cluster of dots on the bottom of CEU represents individuals of majority Scandinavian descent that I know to exist in the dataset.

Scandinavians are under strong selective pressure to keep schizophrenia low, but their high consumption of fish both reduces the power of that pressure and redirects it away from acting directly upon schiz causing alleles and instead improving omega-3 metabolism instead.

The population that has probably been under the most ruthless selection again schiz per se are the Finns, who along with their Estonian cousins have the highest PISA scores in Europe. Pfiffer also calculated them as having highest the Edu Attainment PGS of any Europeans.

Selection against nuttiness may also help to explain the distinctive Nordic personality: in other words, why they’re so boring. The positives to being sane are obvious; the downsides are that you find yourself living in a country where people stare at a burning log on Christmas.
