Document Summary
We look to the environment of evolutionary adaptiveness (eea) to answer why prosocial behavior evolved: ex. We crave sweet and salty food because those were the types of foods that were scarce: prosocial behavior helped out ability to survive. Kin selection: direct fitness, how many children the individual produces. In an everyday situation, the likelihood of saving a woman is most likely for younger ages, but then stays the same as age increases, and higher than saving a man: perceived helplessness might contribute in everyday situations. Odds to save 45-55 year old"s are small in life or death: due to ability to reproduce. In everyday situations, likeliness is highest for ages is highest around young ages and in old ages perceived helplessness: helping in a famine, young children are less likely to be helped, and ages 10-18 are more likely.
