Cormac? Please take note of kmt_sesh's post. That is how to make a skeptical statement worth listening to. He states his experience with the subject, is polite and thorough, and most of all, he gives specific details, especially listing actual traits to look for in source documents that add to or detract from their believability, rather than dismissing them all sight unseen.
Thanks for the kind words, Avallaine. I appreciate your comment. However, let me assure you cormac needs no assistance from me. He can dance circles around most of us with his knowledge of genetics. He's just grumpier than I am.
