Biologicizing Ethics

Biology can explain ethics at all depths. Moral judgements are products of biological causes. Moral behavior is basically altruistic behavior. If the point of life is to live and allow our genes to be reproduced then kin alturism makes perfect sense. In peacocks it was observed that brothers and half brothers stay much closer together than unrelated peacocks. A group of brothers may display themselves to a mate together to out compete the non related peacocks. This is because brothers share most of the same genes so it is in the best intrist of the family that if one peacock is dismissed then his brother will be likely to reproduce instead. Either way the shared genes live on. But what casues unrelated animals to empathize with other members of their species or even other species? Reciprocal altruism explains this. Bonobo chimps do each other favors because they can remeber what they did and who they helped. They are able to remeber this act of kindness and rely on the other animal's reciprocal assistance. They may not be helping to spread their genes directly. But if a monkey is going to starve today he may help someone out in order to get food, live to tomarrow and have a better chance of reproducing another day. This form of ethics is present in many animal societies and has evolved to the morals we know in our human society.
