Comparison of recent and distant past extinction rates with rates at which species are “committed to extinction” during the 21st century (63). E/MSY is number of extinctions per million species years; “Fossil record” refers to the extinction rate of mammals in the fossil record (17); “20th century” refers to documented extinctions in the 20th century—mammals (upper bound), birds, and amphibians (lower bound) (17); “21st century” refers to projections of species committed to extinction according to different global scenarios: vascular plants (38, 18), plants and animals (7), birds (6, 19), and lizards (64). Extinction rate caused by each driver and total extinction rates are discriminated, when possible. (From Sala et al paper)
Sepkoski's (1990) Phanerozoic marine family-level diversity curve, with diversity patterns of Evolutionary faunas delineated and representative members of the Paleozoic Fauna illustrated. The stippled area indicates diversity contributed by poorly preserved groups. Cm, Cambrian evolutionary fauna; Pz, Paleozoic Evolutionary Fauna; Md, Modern Evolutionary Fauna. After Sepkoski, 1990
