Species Selection

Process of selection in which some species are more likely to survive and/or develop into new species; species selection, which is not recognized by all evolutionary biologists, is essentially the differential survival and reproduction of species. Certain species develop mechanisms that result in lower extinction and higher speciation rates (such as primates, and mammals in general); such species will display frequent adaptive radiations. Certain other species develop mechanisms that result in higher extinction and lower speciation rates; such species will display infrequent adaptive radiations.
