An atheist cannot say murder is wrong, then he would have to answer the question why it is wrong, by whose standards, Americas’ standards, Britain’s standards, South Africa’s standards, or maybe by his own standards.
Well, how about a human standard? An atheist is human, after all. The vast majority of humans does not relish the prospect of being murdered, so it stands to reason that murder is almost universally acknowledged as being morally wrong. More generally, most people don't like to be treated wrongly in
any way. So a good rule, one that holds almost universally, would be: "don't do to others what you don't want done to you". This is also known as the Golden Rule and it occurs in almost any culture you care to think of, probably because it is not very hard to come up with. Maybe that's why it's even in the Bible.
And if it's a human standard, then it has evolved, just as any other aspect of human beings has evolved. I don't see why this would be a problem for Darwinism.
