I'm not sure what we are arguing about, or even if we are. I stated what I stated very carefully. The original question, in one of its incarnations, implied that evolution would produce or require unmitigated personal self-interest and would rule out "virtuous" behavior.
If this isn't your position, then I have been posting to the wrong person. There are plenty of people on these threads who claim that belief in evolution would cause a complete lapse of morality. They seem to miss the fact that our moral impulses have survival value, and are indeed rather common in mammals. They certainly aren't rare.

We aren't arguing. I may have skipped an introductory phrase or six in my post. We are coming from pretty much the same position.
I had thought I was just adding an interesting sidelight to your post. It's been one of those busy multi-interruption days. Sorry if I seemed argumentative.
