Simplify and solve this equation: 4m + 9 + 5m – 12 = 42.
a. m = -4
b. m = 4
c. m = –5
d. m = 5

ou would have 12 of each

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.
