Now, what do we know? We know the human genome contains an incredible lot of crap - coding for stuff it doesn't actually do, like lizard traits and fish traits and, yes sir, yeast traits. Why? Why would an intelligent designer create one being with bunches of unused coding for other beings inside of it? The design is inelegant, inefficient, wasteful, and misleading in that it leads others to surmise an evolutionary model when actually She just snapped Her divine fingers and said, "Be".
