If x - y2 = 6 and x - y = 2, find the value of (x + y)2.

Step-by-step explanation:

so so first you have to use that common sense and see what y is equal to and what x is equal to

ab will be equal to

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.
