Humans are able to ignore their close kinship with other animals primarily because of their ignorance of evolution and secondarily because our nearest common ancestor with chimps lived 5 million years ago. If we could see all the species that separate us from chimps, each one virtually indistinguishable from its nearest neighbor, we would much more readily understand that drawing an ethical boundary anywhere along that line of species would be an essentially arbitrary act. Even the biological boundaries between the species are possible only because of the vast extinction of intermediate forms. If we had a complete record of every organism that has ever lived, we would not be able to draw nonarbitrary species boundaries at all and our prejudices for members of our own species would be easily seen to be nonsense.
