Dyma ddiffiniad o'r term:
In evolutionary biology, an adaptive radiation is the evolution of ecological and phenotypic diversity within a rapidly multiplying lineage.[1] 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. [1]
