What number would fill in the question mark?

36 would go in the question mark box. This is because you square each value from the left side to have it match up with the corresponding right side

7 squared = 7^2 = 7*7 = 49 is the upper left box

4 squared = 4^2 = 4*4 = 16 is the upper right box

5 squared = 5^2 = 5*5 = 25 is the lower left box

6 squared = 6^2 = 6*6 = 36 is the lower right box

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.
