The answer is; Biodiversity resulting from few ancestors
Adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. The parts of the population in the different ecologies begin to adapt to their local environments. Due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. They, therefore, diverge to different species sharing a common ancestor.
