Working together, Fred and Laura can finish their history project in 3 hours. Had Laura done it
alone, it would have taken her 4 hours. Find out
how long it would take Fred to do the project
alone.

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.
