Developing our complete theory of kindness Shared genes: families, relatives Reciprocity: doing something for people who are not related so that they can get something in return later. Predictions of Kin selection 1. Murder: more non-relatives killed than relatives among cohabitants (people living together) 2. Infanticide: children in step-families injured or killed more frequently than those living with their biological parents 3. Bequests: Individuals will leave more of their estate to close kids than distant kids kin selection helps us understand what we are doing we act based on coefficient of relatedness among unrelated individuals, selfishness is the rule, kindness is the exception bike sharing programs o people keep stealing bikes o individuals act on self interests rather than what’s best for the group Animal friendship: None; cooperation among non-kin is almost non-existent in the animal world Vampire bats: suck blood for food
