What is altruism? Two broad types of altruism? What are 4 evolutionary theories that attempt to explain altruism (briefly describe each)? Which two theories best explain altruism to total strangers? Which best explains altruism to genetically unrelated friends?

Any action that benefits another at some cost to the self. Heroic and Everyday. Kin Selection Theory- helming relatives helps spread our own genes. Reciprocal Alturism Theory- the feelings that favors will be returned in the future. Costly Display Theory- having the resources to spare to help someone. Group Selection Theory- competing over resources, groups with more altruists are more likely to win. Costly and Group. Reciprocal.

much of the structure of the human mind is innate, contrary to the proposal that the mind consists of little more than a general purpose learning mechanism, nature rather than nurture is emphasized. the human mind is largely the product of natural selection, developed over evolutionary history to solve adaptive problems confronting our species, survival rather than reproduction. The human mind is highly composed specialized cognitive systems or modules that evolved to deal with specific problems.
