Point R has coordinates (-5, -7) and point I habucoordinates (3, -3). Which point is located 1/4 of the distance from point R to point T?
Enter x-coordinate of the point here :

and the y
coordinate of the point here :

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.
