How long so you have to drive at 45 mph to get to 1 mile?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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.
