Religious people split into three main groups when faced with science. I shall label them the "know-nothings", the "know-alls", and the "no-contests."

It would be really worrying if, as a Darwinian, it was impossible to think of ways in which our behavior could be explained.

Do those people who hold up the Bible as an inspiration to moral rectitude have the slightest notion of what is actually written in it?

Science replaces private prejudice with public, verifiable evidence.

Again, it is belief without evidence. In the case of Stalinism, people actually distorted science, because it was for the good of the Communist Party.

Have they discovered evolution yet?

In our prehistoric past, we would have lived in extended families, surrounded by kin whose interests we might have wanted to promote because they shared our genes. Now we live in big cities. We are not among kin nor people who will ever reciprocate our good deeds. It doesn't matter. Just as people engaged in sex with contraception are not aware of being motivated by a drive to have babies, it doesn't cross our mind that the reason for do-gooding is based in the fact that our primitive ancestors lived in small groups.
