Words of Comfort: Tailbone

I was speaking recently to a group of university students. When I said that I didn’t believe in evolution--that it was unscientific and unobservable, an atheist called out, “But what about the tail bone?” The human tailbone is said to be vestigial—that is, it’s an evolutionary left-over proving that we are related to primates. I said that it’s not a “tailbone,” but that it’s the coccyx vertebrae, and that it’s the anchor for 12 muscles that make it possible for us go to the bathroom: “The tailbone derived its name because some people believe it is a ‘leftover’ part from human evolution, though the notion that the tailbone serves no purpose is wrong. The coccyx is an extremely important source of attachment for tendons, ligaments, and muscles, though it is structured quite differently than other parts of the spine.”[1]

Of course this believer in evolution didn’t concede for a moment, and called out, “What about the appendix?” I then explained that the appendix, like the “tail bone,” isn’t vestigial in the slightest, and that it’s tied in with the human immune system. When he mocked that thought, I told him to Google it. Duke University said: “Appendix Isn't Useless at All: It's a Safe House for Bacteria, By Duke Medicine News and Communications. Long denigrated as vestigial or useless, the appendix now appears to have a reason to be -- as a ‘safe house’ for the beneficial bacteria living in the human gut.”[2] And so it is with each of the “evidences” that are held up as proof for the bogus science that is believed by so many.
