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. A detailed discussion of its phylogenetic position appears along with figures of the tree. This means there is significant potential for conservation action to mitigate the effect human activities have on the amphibian tree of life, Jetz said. With many species still insufficiently studied in the wild to appreciate their risk of extinction or potential functions for the ecosystem, the researchers said, knowing their evolutionary distinctness and place on the family tree can provide invaluable insights. Females are slightly larger than males, reaching (body) lengths of up to 14 cm (5.5 in).

These results clarify several contentious portions of the amphibian Tree of Life, which in conjunction with a set of vetted fossil calibrations, support a surprisingly younger timescale for crown and ordinal amphibian diversification than previously reported.
