    Mass extinctions promote rapid expansion and diversification of surviving species into newly available niches.

      There’s also a Hypothesis iirc that this rapid expansion also lowered our life span. Longevity Bottleneck Hypothesis though I think this one includes dinosaurs hunting mammals, and maybe Disposable Soma Theory.

      Huh, the second one could probably be used to explain elves in fantasy: long life, low reproduction rate.
