Maybe it's half-assed, or maybe you're just being careful not to over-commit. Better to take some steps than none at all, and you might as well go about it in a way that feels sustainable :)

Yeah I don't know enough about anthropology to comment on whether or not eating meat has been normal throughout our evolution. I suspect it's not as cut-and-dry as "we've never been meat eaters" but it was also probably a minimal part of the diet. And it probably varied widely depending on location.
