Evolution of different species in a said area starting form a certain point and spreading to or geographical areas is known as

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, creates new challenges 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. So, evolution of different species in a said area starting from a certain point and spreading to other geographical areas is known as adaptive radiation.
