May i know the answer for this –5(t − 70) = –60

-5(t - 70) = -60

t - 70 = 12 -- Divide by -5

t = 82 -- Add 70

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.
