Definitions for adaptive radiation
This page provides all possible meanings and translations of the word adaptive radiation
the development of many different forms from an originally homogeneous group of organisms as they fill different ecological niches
the diversification of species into separate forms that each adapt to occupy a specific environmental niche
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available and opens environmental niches. Starting with a recent single ancestor, this process results in the speciation and phenotypic adaptation of an array of species exhibiting different morphological and physiological traits with which they can exploit a range of divergent environments. Adaptive radiation, a characteristic example of cladogenesis, can be graphically illustrated as a "bush", or clade, of coexisting species.
