James keeps his socks separately in a drawer. The drawer contains four red socks , five white socks and six black socks.
He dressed in the dark one morning and pulls out two socks without looking .
What is the probability that he takes two socks of the same color?

P(taking 2 socks of same cllour) = 1/15

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.
