23. There are 25 students in Roses's Speech class. Rose has not yet been called on to give her required oral report, but 10 other students have given
their reports. If 2 students are absent, what is the probability that Rose will
be called on to give her report assuming one student gives a report each
day.
A) 10/13
B) 1/23
O C) 1/13
D) 10/23

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.
