A Recent Mass Extinction--How Long Must Life Reel Itself Back In?

In our understanding of mass extinction and adaptive radiation, we have found that life can't and doesn't bounce back right away. They take time. It took life eight to ten million years to recover from the worst mass extinction in Earth's history. In the aftermath of the Mesozoic-Cenozoic Extinction Event, life bounced back after at least 100,000 years.

But what about a more recent mass extinction? Would life today still be on the verge of recovery if there were an extinction event merely five million years ago?
