I recommend Kropotkin's book about Mutual Aid regarding this topic. Disregarding his obvious political affiliation he is one of the first critics of the then-emerging social-darwinist readings of animal behaviour with regards to Evolution and therefore deals with this topic quite extensively.
He was a zoologist apart from all the other topics he had time to deal in because of his noble heritage. Here is the wikipedia article [0] since I do not know how HN regards links to e.g. libgen.
That'd make him one of the last of the old-line ethologists, before the dark interregnum of the behaviorist scum began - I respect Kropotkin considerably more now than I did five minutes ago. Perhaps I'll read him after all.
