Amphibians represent key victims and bellwethers of global change, and the need for action to conserve them is drastically outpacing knowledge. The Evogeneao Tree of Life diagram, and the generation counting technique used herein, was inspired by Dr. Richard Dawkins’ wonderful book The Ancestor's Tale.The smallest branches are purely illustrative and help to suggest the effect of mass extinctions on diversity, and changes in diversity through time. Abstract The evidentiary basis of the currently accepted classification of living amphibians is discussed and shown not to warrant the degree of authority conferred on it by use and tradition.

Peer Reviewed A new study by researchers at Yale and George Washington University examines the human threats to the amphibian family tree and calls for a rethinking of conservation priorities to preserve species diversity and evolutionary heritage. "Amphibians are a globally endangered group for which threats from global change are outpacing our ability to safeguard species," said Walter Jetz, lead author of a paper published online March 26 in the journal Nature Ecology & Evolution. "We expect this information to be widely helpful for the large community of scientists and conservationists interested in amphibians, and to empower national and local conservation efforts.

They inhabit pools and slow-moving streams in subtropical forests. Amphibians represent key victims and bellwethers of global change, and the need for action to conserve them is drastically outpacing knowledge.

Amphibians are members of the class Amphibia.The living ones are frogs (including toads), salamanders (including newts) and caecilians.They are four-legged vertebrates which are cold blooded.. Amphibians lay their eggs in water, usually in a foam nest.After hatching they are tadpoles, which live in the water and have gills.The tadpoles change into adults in a process called metamorphosis. The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life.
