For an even better overall summary, I suggest the next time you're in a library you read an article in Scientific American's May 2002 issue, The Mammals that Conquered the Sea. Unfortunately, that one's not on their web site. It gives you a somewhat less skewed version than you get from asking the slimy lawyer for one side.
Maybe I shouldn't exactly use that characterization. Everyone assumes Andrew doesn't believe in evolution. In the incident of the Abuse Button, he was trying to use that instrument to stop me from outing him before God's Traveler, who satteth at the right hand of God but gotteth banned anyway. "Out" him, how? Andrew's theistic evolution is only barely microscopically removed from Junior's. In Andrew's version, God or God's design lurk somewhere down in the cell machinery producing non-random mutations. Above that level, it all looks the same. Common descent, natural selection, evolution.
You wouldn't know that, would you? It's a big secret. He's like a closet homosexual who runs about yelling "Faggot! Queer!" Thus it is necessary to keep the discussion away from what he actually believes, at least until he's taking too much flack for dodging.
But I digress. The telling point was the finding of the post-cranial Pakicetus bones--paleontological evidence. And Mesonychus with its cetacean-looking skull is still under consideration. One thing that would decide the question one way or the other are the ankle bones of an older Mesonychid or a likely near-ancestor of Mesonychids--more paleontological evidence.
Why don't you read post 204 before you display your lack of reading skills. But you are to busy with Ad hominem to do that.
