I can't remember where I first ran across this video. (Which is pretty pathetic since it just a couple of hours ago.) It deals with how eyes evolve in invertebrates and takes on a classic "intelligent design" argument that some organs, like the eye, are simply too complicated to have ever evolved without some sort of master "designer" interfering.
