Document Summary
Cooperative breeding: scrub jay forgo looking after themselves, reproducing and help whoever nest has offspring, bee-eaters forgo breeding and helps other adults raise their young, meer-cats unrelated individuals help out other meerkats. A special difficulty, which at first appeared to me insuperable [unsolvable], and actually fatal to my theory . Darwin: darwin thought of natural selection at the individual level but cooperation makes it fall apart. Developed during the cold war relative to both economics and evolutionary biology found by nash. Explanation of game theory: some number of players, set of possible strategies, some pay-off schedule for playing a against b and for all times a and b. Contest between two individuals over obtaining a resource two strategies can be used: hawk strategy fight aggressively over the resource, dove strategy resolve contest peacefully, r = reward; c = cost of fighting. In the hawk/dove game there will be 2 players, 2 strategies and a pay-off matrix.
