Hi mate

This goes a bit beyond that and looks at venom evolving at snake family level relationships rather than individual genera. There has already been a very good paper by Utiger et al on the ratsnake taxonomy. Elaphe has of course been a taxonomical dumping ground for a large, disparate group of snakes that only superficially resemble each other but it turns out that there are several full genera lurking within there. This is the same situation that happened with the 'colubrids', with anything that wasn't obviously and elapid or viper being thrown in there, however it turns out that there are a half dozen families in there, some of which are much much closer to cobras than to cornsnakes.

Cheers
