Form the intersection for the following sets. X = {0, 10, 100, 1000}

Y = {100, 1000}

X ∩ Y =

it's both, now can you answer my most recent question?

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.
