It took some 10 million years for Earth to recover from the greatest mass extinction of all time, latest research has revealed.
So. Yeah. That’s how long it takes a planet to recover from an apocalyptic sequence of massive physical environmental shocks.
We often see mass extinctions as entirely negative but in this most devastating case, life did recover, after many millions of years, and new groups emerged. The event had re-set evolution. However, the causes of the killing – global warming, acid rain, ocean acidification – sound eerily familiar to us today. Perhaps we can learn something from these ancient events.
