Apparently you haven't even heard of them. Sad. I had hoped for a better-educated opponent.
If you scroll back, what I said was that evolution was the only theory which explains the data [regarding proliferation of species]. I'm dimly -- oh so dimly -- aware that there are other theories around, but none which do the job of evolution, that is, explaining the fossil data, DNA data, and the proliferation of species in the world. The only competing "theories" propounded in these threads are (1) Genesis; and (2) flying saucer Johnny Appleseeds, a/k/a Intelligent Design. Neither of those is a scientific theory. If you have one, bring it on.
