Some ideas for real human biodiversity (HBD) research

Breastmilk production, nutritional variation, infant and toddler behavior, conception differences.

Just a few little things.  It’s unfortunate that the term “human biodiversity” has pretty much been hijacked by people obsessed with test scores or proxies for test scores (and proxy can mean “pulled straight from nether regions” as often as it means “reasonable substitute for a test score”).  I do think it would be nice if the idea that we all are shaped in different ways by our surroundings wasn’t linked up with the idea of scientific racism or SAT scores and little beyond that.
