I believe human altruism arose as a commensal strategy. As a cave man, I can't defend my family from predators as well alone. In a group, working together, we do better. If I'm only self interested, I might ensure I'm the sole survivor, but not for long. If I'm altruistic, I can help to ensure the survival of my tribe, and then they will better ensure the survival of me and my progeny.
Altruism is the price we pay for the benefits of society.
