Yes indeed colubridae is a catchall, and it needs to catch less. I imagine, all the snakes are going to be redone as MtDna will change all this stuff. So no need to go on and on.
Its fairly obvious that hogs are different in many ways from Rats and kings, not just looks, but also reproductively as well. And of course behaviorally.
Of course, I have nothing to do with taxonomy. I like stuff that's solid like behavior. Wait, that's worse then taxonomy.
