The main (only?) argument for evolution is that similarities between living things are due to relatedness, or common ancestry. If two kinds of animals share a lot of common features, then they are ‘obviously’ closely related and so must have had a recent common ancestor—or so the evolutionary reasoning goes.1,2 Birds, for example, all lay eggs, have feathers and a specialized lung comprised of interconnected air sacs, so the evolutionist would say all birds had a common ancestor which had these features. Creationists would say that birds have these similarities because they were created with a common basic plan. People would assume that because my friend and I were so similar we must have shared a very recent common ancestor—like the same parents. They were wrong. In like manner, the evolutionists are often—not always—wrong in assuming similarity is due to common ancestry. Of course my friend and I are members of the same human kind and so we know that we had a common ancestor—who was
