Figure: The average amount of evolution per species for the major groups of vertebrates. The average shark species embodies twice the amount of evolution as the average amphibian or reptile species, and four times as much as the average bird species. Over 20% of sharks and rays are at risk of extinction, approximately the same level as mammals, and twice the level as birds. Crocodiles and turtles are, unfortunately in even worse shape.
