Posted by: epidemic at Thu Sep 21 12:18:42 2006 [ Email Message ] [ Show All Posts by epidemic ] The snake could indeed be an atavism, as Professor Cao Shandong has indicated. An atavism being an organism that is a real or supposed evolutionary throwback; the unexpected appearance of primitive traits, or a reversion to or reappearance of a trait that had been present in a lineage in the past, but which had been absent in intervening generations. Atavisms occur because genes for previously existing phenotypical features are often preserved in DNA, even though the genes are not expressed in some or most of the organisms possessing them.
