In case anyone is curious, https://en.wikipedia.org/wiki/Dual_inheritance_theory https://en.wikipedia.org/wiki/Dual_inheritance_theory mentions the canonical example of cultural and genetic coëvolution: lactose (in)tolerance.
In particular, in the given hypothetical, one might predict a change in the dairy culture in Japan if suddenly the population was significantly more tolerant of lactose.
(I assume the usual example of lactose intolerant is chosen because it appears some people are otherwise religiously opposed to considering the relationship between culture and genetics.)
- fluoridation 4y ago>one might predict a change in the dairy culture in Japan if suddenly the population was significantly more tolerant of lactose. It might change or it might not. Just because a dietary option is open to you doesn't mean you're going to take it. Nothing prevents me from eating sushi, and I still don't, and the reason is obvious: I didn't grow up eating it, so it isn't part of my normal diet. It's one thing to say that culture and genetics are not completely independent. It's another to say that culture is heavily influenced by genetics, to the extent that it's a hereditary trait.
