Find the rate of change given the following solutions: (6, 2) and (1, 12).

The rate of change is -2

Step-by-step explanation:

f(b)-f(a)     12-2              10

=  = = -2

 b-a         1-6               -5

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.
