Altruism (-,+)

Cost to donor, benefit to recipient ("selfless behavior")
Does not lead to direct fitness (the fitness an individual gains by passing genes to its offspring)

Altruism is really "apparent altruism"

-the idea that altruistic acts may actually be cooperative

-the donor may eventually benefit

-two main mechanisms proposed

Reciprocal "Altruism": expectation that the other organism will act in a similar manner at a later time.
Kin Selection: Altruistic behavior increases the fitness a relative and in so indirectly increases the fitness of the altruist
