This is racism, a highly prejudicial school of thought that tends to dehumanize fellow human beings. One cannot say that evolutionists today are racists. Racism is unpopular today, and public acknowledgement of it is even more so. However, many evolutionists in the several generations following Darwin, and even Charles Darwin himself, were racists. The theory of evolution provides a very convincing rationale to justify racism.
Genesis provides a quite different historical perspective.
We are all descended from Adam and Eve and Noah and his wife. Consequently, we are all cousins.
