which statement is true?
the mean, median, and mode are all appropriate measures of center.
both the median and mode are appropriate measures of center.
both the mean and median are appropriate measures of center.
the median is the only appropriate measure of center.

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.
