Agrocery store sign indicates that bananas are 6 for $1.50 and a sign by the oranges indicates that they are 5 for $3.00 find the total cost of buying 2 bananas and 2 oranges

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.
