In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
An evolutionary radiation is an increase in taxonomic diversity that is caused by elevated rates of speciation, [1] that may or may not be associated with an increase in morphological disparity. [2] A significantly large and diverse radiation within a relatively short geologic time scale (e.g. a period or epoch ) is often referred to as an ...
This is a list of adaptive radiated marsupials by form; they are adaptively radiated marsupial species equivalent to the many niche-types of non-marsupial mammals. Many of the surviving species are from Australia. There are unique types, for example the extinct genus Nototherium, a 'rhinoceros-type'. [1]
