The critical period of human development is between birth and puberty, but the earlier introduction of the correct nutrition can has a lifetime of impact.

yeah. intelligence is developed in that early period. so is language (And fetishes, iirc)

that's why i think a lot of IQ data over mass populations is at issue. you can't test kids at like 8-10 and get a picture of what their IQ would have been had they been raised under the most optimal circumstances

I'd wager that vitamin D levels, which are lower in people with dark skin, might have something to do with intelligence as well, and indeed, there are a couple of papers out there that suggest a causal relationship between vitamin D and cognitive development.

that's interesting

all the biology becomes irrelevant if intelligence is not harvested and developed, though. that's why culture matters

the sad part is that modern progs reject both the biological and cultural issues involved
