A quick question regarding the classification of amphibians

Postby TheGreatPretender » Fri Oct 22, 2010 4:51 am

Since amphibia is a paraphyletic group, why is it not discarded? Why do some biologists argue in favor of keeping the term?

Hmm, I'm not sure all this stuff about cladistics is really helpful you know! It's all a bit picky, picky, picky....

Having checked the redoubtable Wiki (!), it seems that only the extinct Labyrithinodontia is (was!) paraphyletic...?

To be honest, I would say that it's an excellent idea to give amphibians a single group to belong to, because they have such uniquely distinguishingly characteristics - they're not fish, they're not reptiles, they're 'in-between'.... :).

Yes, of course it's useful - possibly even necessary! - to understand the precise course of evolution, what evolved from what etc etc, but I think there's also a cogent argument for saying that the nomenclaturists can end up disappearing down a hole in the ground.

I suppose biology does need some taxonomists - but not that many!!! It just puts students off.... :)
