A college student would like to investigate the prices of sandwiches offered near the campus

A sample of 50 shops that sell sandwiches near the campus was taken and the price they charge for a large sandwich was recorded. The results are displayed in the cumulative relative frequency histogram below.

Step-by-step explanation:

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.
