Which rule shows a dilation? O (x, y) = (x+8y) 0 (x, y) → (x-7.y+3) O (x, y) → (x, y+ 3) Oxy) → (2x, 2y)​

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.
