It takes a village… Oh how nice, yes we all get together and raise the children communally… Umm, actually it takes a village of relatives – In the EEA we lived in family groups

Families Basically kin The idea of groups of relatives that stay together after sexual maturity Helpers at the nest Plus reciprocal altruism

Parent Offspring Conflict If there is investment, the offspring would like it to go on forever, the parents, eventually want to have more babies OK, look at this genetically, the mother and daughter/son share.5 of their genes At some point, the mother would be better served by having another child.

Parent offspring conflict The conflict continues until the parental cost = 2 x the benefits to the offspring Then, it is in the best interests of the parent and the kid to have another kid show up Not just the continuation of investment, but also the amount can be a bone of contention

Sibling rivalry Well you share.5 of your genes with your brother or sister, but 1.0 with yourself Monozygotic twins should be nicer to each other than dizygotic twins are Data are not too clear here

sharing Makes sense to teach your kids to be nice Especially to relatives However also to strangers in the right situation Good for you and your kids
