| - Champion speciators are usually prolific, very hardy, a generalistic species, must be (or was) widespread, and must have a diverse and random gene pool. In other words, they have a lot of babies, can find a way to live most anywhere, eat a variety of different foods, obviously must have been spread over a large area, and must be able to have mutations out of nowhere that could be beneficial to the species.

| - Champion speciators are usually prolific, very hardy, a generalistic species, must be (or was) widespread, and must have a diverse and random gene pool. In other words, they have a lot of babies, can find a way to live most anywhere, eat a variety of different foods, obviously must have been spread over a large area, and must be able to have mutations out of nowhere that could be beneficial to the species. Supertaxa are a group of animals that rapidly evolve and once they evolve they rarely go extinct (high origination rates & low extinction rates). Endemic species (high origination rates but high extinction rates) are also (usually) prolific but are (usually) so specialized to the point it is hard to mutate their way out of extinction. The last group, living fossils are different than either earlier two, (low extinction rates but also low origination rates) the evolve as a generalist and it takes them quite a bit of time to specialize (even by geological standpoints). Endemic taxa are champion speciators, but they need to survive long enough to speciate. Supertaxon are obviously the champion speciators. Let's consider the orders of land vertebrates, their number of species and the timespan they have existed on Earth: we can compare their capacity to produce species by measuring how many species they produced, as an average, for each million of years (Ma) of evolution. These are the orders that have a species/time ratio above 5 (data from Wikipedia):
