The diagram shows a regular pentagon with centre 0. Work out the size of angle x.

Step-by-step explanation:

1. Use exterior angles (each adds up to 360) to find interior angles

2. Add this together

3.Take it away from 360

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.
