I think you could say that any absolute morality is rooted in whatever is evolutionarily necessary for progress in a society.

However, biological evolution, as I have said, in a large part stops at consciousness. We are self-destructive, we help the weak rather than let them perish, and different societies form different ideas about crime, taboo, and ethics.

Killing is bad. But there is no consensus as to how bad. Some people think murderers should be killed, others think they should live in prison forever, some think they should be rehabilitated and released. In old Scandinavia, fines were paid for killing rather than a more formalized punishment.

I think in order for a point of morality to be "absolute", it has to be hopelessly broad.
