For mass extinctions there is the common explanation that it takes a long time after each extinction before enough diversity is built up again for another major extinction.
For example after the current Anthropocene one we likely won't have another one any time soon because there is not enough diversity left for a true mass extinction.
That gives a natural effect where mass extinctions are spaced with some minimum interval. They're not independent events.
