Quote:Biologists take for granted that the limbs and branches of the tree of life - painstakingly constructed since Linnaeus started classifying organisms 270 years ago - are basically correct. New genetic studies, the thinking goes, will only prune the twigs, perhaps shuffling around a few species here and there.
Hence the surprise when a new University of California, Berkeley, study of the largest family of salamanders produced a genetic family tree totally inconsistent with the accepted classification, which is based primarily on physical features...
