What is the name of the point where the x- and y-axes intersect? what are the coordinates of this point. will give branilyest

The name of the point where the x and y axes meet is called the origin, and the coordinates of the origin is (0,0).

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.
