What are some non-price level factors that cause the aggregate demand curve to shift left or right (and in which direction will the ad curve shift for each of these)? also, what are some non-price level factors that cause the aggregate supply curve to shift left or right?

step-by-step explanation:

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.
