What is the y-intercept of this graph?

0,0

Step-by-step explanation:

To find y-intercept You look where the line touches the y-axis and vice-versa if you want to find teh x-intercept

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.
