answer: ur v dumb
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.

5 to the power of 2 is 25
2 multiplied by 5 is 10
then you add the 2 numbers and you get 35
