Life’s great radiations do not always line up with mass extinctions, a new study shows

Life finds a way. Paleontologists have reiterated that maxim over and over, often drawing from the way organisms seemed to bounce back from the five mass extinctions Earth has suffered. These events winnowed down the number of species alive on the planet, the story goes. And the survivors set the foundation for life to flower again the way a forest can be refreshed by fire. But a new study suggests that paleontologists may be off tempo. Some of the greatest evolutionary radiations of all time happened without a mass extinction to spark them, and not every disaster opened space for new life.

In fact, scientists now know that most species that have ever existed are extinct. This extinction of species has on the whole been roughly balanced by the origination of new ones over Earth s history, with a few major temporary imbalances scientists call mass extinction events.
