Americans don't want an atheist president

Some common examples:
- Animals do not, in general, kill their own kind, except in very specialized circumstances. With some species you see a specific "surrender" behavior which allows the loser to retreat instead of being killed.
- In higher species, mothers protect their young. Herd or pack animals protect the young collectively.
- Animals that compete tend to "fight fair". Peacocks try to impress mates with their tail feather display, and weaver birds do it with the nests they build, but you don't see peacocks tearing each other's tails out, or weaver birds breaking each other's nest.

A lot of insects/all spiders eat their mate after mating, that's some serious morals.
