There are two bags containing only black and white marbles. Bag A has 9 white marbles and 3 black marbles. Bag B has 8 white marbles and 12 black marbles. A marble is randomly chosen from each bag.
List these events from least likely to most likely.
Event 1: choosing a white or black marble from Bag B.
Event 2: choosing a white marble from Bag A.
Event 3: choosing a black marble from Bag B.
Event 4: choosing a blue marble from Bag A.

I prob messed up

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.
