What does it mean if the probability is 20% that a spinner will stop in a red section? a. there is one chance in 5 that the spinner will stop in a red section. b. there is one chance in 20 that the spinner will stop in a red section. c. if the spinner is spun 100 times it is certain that it will stop in the red section exactly 20 times. d. it is 20 times more likely that the spinner will stop in a red section than any other section.

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.
