In the figure below, AABC = ADEF. Point C is the point of intersection between AG and BF, while point E is the point of intersection between DG
and BF. Prove ABC ~GEC.

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.
