Okay, it's one of those unexplainable things, just like the Creationists' plausible explanations of the birth of the world, and the Scientists' approach to explanining the unexplainable by scientific methods. It's a whole other X-Files. Let me say that I have enjoyed the posts, but my finger is getting tired of deleting it all. But I will perservere, and will continue to believe that it's a whole conspiracy to make me feel better about the discredited "Big Bang Theorgy" or that the Titans and the Olympians really did start the "ball" rolling. In the meantime, the delete key still rules. O Olivia S.

Ummm....how does one account for the piscine gills which occur in all mammalian embryos? And, for that matter, whales, which are mammals which have taken back both the watery environment and activities of fish?
