Given P(A) = 0.5, P(B) = 0.37 and P(A and B) = 0.245, find the value of P(AB), rounding to the nearest thousandth, if necessary.

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.
