Talk:Lissamphibia

From Wikipedia, the free encyclopedia

This article is part of WikiProject Amphibians and Reptiles, an attempt at creating a standardized, informative, comprehensive and easy-to-use amphibians and reptiles resource. If you would like to participate, you can choose to edit this article, or visit the project page for more information.

I suggest this page belongs in page "Amphibia"/"Amphibian". Please see the Talk:Anura page where I hope we can coordinate all things Amphibian. Stanskis 02:37, 17 July 2005 (UTC)

Lissamphibia is a specific subclass of Amphibia. So unless you adopt a cladistic crown group definition of a monophyletic Lissamphibia, (in which case "Lissamphibia" = "Amphibia" and all other prehistoric amphibians are cladistically defined either as "tetrapods" or "four-legged animals") the two are not synonymous.

so, in short:

• it is not agreed that Lissamphibia are monophyletic
• the stem group interpretation is just as valid as the crown group interpretation, if we use this than Amphibia is not the same as Lissamphia even assuming the latter is a monophyletic taxon
• while the cladistic explanation is being widely (and increasingly) adopted there are still those who prefer the Linnean taxonomy

for all these reasons, Lissamphibia should not be merged with Amphibia M Alan Kazlev 04:23, 18 July 2005 (UTC)
