h = -9

Step-by-step explanation:

2(h + 3.5) = -11

2h + 7 = -11

subtract 7 from both sides of the equation:

2h = -18

divide both sides by 2:

h = -9

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.
