Factor the polynomial 4x4 - 20.x² – 3x² + 15 by grouping. What is the resulting expression?
O (4x² + 3)(x2-5)
O (4x2 – 3)(x2-5)
O (4x² - 5)(x² + 3)
O (4x² + 5)(x² – 3)

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.
