WebAdaptive radiation, in the case of evolutionary biology, is a process which highlights rapid diversification of organisms from their ancestor in some new forms because of some newly introduced resources in the changed environment. This adaptation is the result of different responses by a species to the same change in environment. WebThe evolution of hyposdonty represents a key adaptation involved in many ungulate adaptive radiations.
