Document Summary
Reciprocal altruism: even if an animal is not related to the thing they"re helping, they will still help because they expect the thing to reciprocate. Tit-for-tat strategy: where you cooperate first, then you defect if your opponent defects, and then you try cooperating again. Frequency dependent behavior: if you have all cheaters, and one tit-for-tat member, the tit- for-tat member can"t do better but can do equal. Hawk-done game: think of doves as individuals that don"t fight, and hawks fight when two doves meet everything is good, when a hawk and dove meet the hawk eats the dove, when two hawks meet they fight. Public good game: you have resources and you can choose if you want to return a fraction of your resources to the public (like taxes) Anisogamy: the idea that male gametes and female gametes are asymmetrical. Polygamy: not biologically surprising, because it is the typical pattern seen in the animal world.
