Subtract the equations
A. 4x=14
B. 4y=20
C. 10x=20
D. -4y=14

4x= 14

Step-by-step explanation:

Break down the equation for easy understanding

Now solve the above equations

Now put them back together

what's that

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.
