An obvious bit of evidence of east asian’s more neotenous than europeans: they still retain the epicanthal fold (inner eyelid) which humans normally mature out of before birth. The others are body shape, body hair, scent, degree of sexual development. Conversely afro-asiatics (arabs) and africans mature more deeply than europeans. We make jokes about size of genitalia but it’s true. you can measure group neoteny by size. And again, as in all things, stereotypes are the most accurate measure in the social sciences.
The genes that control for intelligence have vast secondary effects on the facial structure, which is probably why we are so good at estimating intelligence from a glance at faces.
