Posted by: Sirtalis at Fri Sep 5 13:42:05 2003 [ Email Message ] [ Show All Posts by Sirtalis ] My apologies for what is probably very much a beginner's question. I am curious when (what year) new world water snakes (Nerodia) split from the old world equivalent (Natrix). Further, which trait, genetic or otherwise, was found to differ enough to warrant the distinction, or was it mostly geographic? Thanks for any insight... [ Hide Replies ]
