The area of each square below is 1 square unit. How can we describe the area of the striped region?

Choose 1
A 2/3x5/4
B 10/15x5/10
C 3/4x3/2

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.
