Idon’t even know what does exterior angles theorem means

Exterior angle theorem states that the measure of the exterior angle is equal to the sum of the two opposite interior(inside) angle of a triangle

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.
