Why was there no sexual selection or evolution towards tropical bodytypes in the americas and instead native americans mostly kept their square short stocky bodytypes of their siberian ancestors?
>>18454031It takes far longer to evolve in a climate than the timespan Natives have lived here. Also things like clothing and living in tents can affect how genes are selected because you aren’t just selecting for the environment anymore.
sexual selection only happens if the population can afford it
Sexual selection is disgenic
>>18454031how do you know latinxers didn't sexually select for fridge-mode squatemalan goblins?
>>18454031They probably arrived already with sufficient technology that stocky people would survive. Like for example natives of the far north developed chink slit eyes to deal with snow blindness, but they have been using facemasks for over 10 thousand years so that selection pressure has not been acting for a long time.
>>18454031All I know is that Indians of the United states and Canada tended to be described as taller than the European explorers that encountered them.

>>18454031they were agricucks by 8000 BC, being stocky has its advantages on the farmnorth plains indians and amazonians had a different build, they procured food hunting big game, small game, trapping, fishing, some would deliberately burn sections of forest to plant wild varieties a low productivity yet low labor form of farming which produces crops rich in protein, fiber and antioxidants instead of starchy corn and potatoes, as such they had a different pheno
