We find that foraging humans forage, reproduce, share parenting, and even organise their social groups in similar ways as surrounding mammal and bird species, depending on where they live in the world. Our results imply that local environments exert a key influence on how foraging human populations and non-human species behave, despite their very different backgrounds. Local environmental conditions select for similar foraging, social, and reproductive behaviors across human foragers and non-human animals, driving behavioral diversity worldwide.
