You are riding your bike and notice the square sign above. You mentally draw a straight line from point A to C. Describe the angle relationship between ∠DCA and ∠BCA. (2 points)

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.
