Document Summary

We are not born knowing who our kin our - we have to figure that out. Why do we discriminate against kin: target altruism towards them, avoid harming them too much, avoid mating with close kin. We are less attracted to people who are our kin. We must learn who our kin are. Plants - complete less when growing next to kin. Potential proximate mechanisms: aversion and/or complete sexual non-attraction, genuine their concern for well being: one proposed mechanism on how we integrate cues to learn who kin are (lieberman et al, cues of kinship: situational predictors. If we were born in the same house it is likely that we are siblings. It was suggested by westermarck (1891) that we are not sexually attracted to those whom they grow up with from childhood: evidence that taboos not wholly responsible for incest avoidance. Non-human animals: even non-animals avoid incest - even without taboo.
