• Diarrhea and the Appendix are Signs of Intelligent Design

    In my new book, Foresight: How the Chemistry of Life Reveals Planning and Purpose, I argue that the synergistic action of diarrhea and the appendix provides a strong case for foresight and thus for intelligent design. Jerry Coyne, writing at Why Evolution Is True, has responded. For that I am grateful. See, “ID craziness: Diarrhea and the appendix are signs of intelligent design.” I wish, enthusiastically, to reply. The subject under discussion is so-called vestigial organs, specifically the appendix. For decades we were told that — due to evolution — our body includes organs that have lost their functions and are therefore in the process of being eliminated. Dr. Coyne adds that some of those condemned organs, by accidently finding other functions, may get lucky enough to escape extinction. This is possible, I agree. The “vestigial organs” are taken as strong evidence for evolution and against ID. After all, an intelligent designer would have no use for useless organs. With that I also agree. However, we must let the data speak. When we do, learning more about the physiology of our body, we find that “vestigial organs” have amazing functions after all.
