For me, this is very surprising.
> For example, when obtaining food, there are environments where humans get a significant proportion of their calories from hunting. In these locations it was shown there are much larger proportions of carnivorous mammals and birds than elsewhere.
I would have expected that the hunting-niche filled up, so that it was rather anti-correlated. One species eats more meat another eats less.
For sexual behavior, I suppose I could see the geography (how big island in particular - is that where they find these "human populations who obtain most of their food by foraging in the environment where they live") playing a part. If people have to travel by water to find a mate that could change things.
