Which inequality pairs with ys-2x-1 to complete the system of linear inequalities represented by the graph?
Oy<-2x+2
O y>-2x+2
O y<2x-2
O 2x-
y>2x-2

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.
