As you look at the general trends of the graph, what happens to the biodiversity when a mass extinction happens? Why?

Explanation:

As lineages invade different niches and become isolated from one another, they split, regenerating some of the diversity that was wiped out by the mass extinction. The upshot of all these processes is that mass extinctions tend to be followed by periods of rapid diversification and adaptive radiation.
