Scientific American Life’s great radiations do not always line up with mass extinctions, a new study shows Advertisement 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 r...

Charles Darwin’s landmark opus,  On the Origin of the Species, ends with a beautiful summary of his theory of evolution, “There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.” In fact, scientists now know that most species that have ever existed are extinct. This extinction of species has on the whole been roughly ba...
