It takes at least 10 million years for life to fully recover after a mass extinction, a speed limit for the recovery of species diversity that is well known among scientists. Explanations for this apparent rule have usually invoked environmental factors, but research led by The University of Texas at Austin links the lag to… Continue Reading Evolution Imposes “Speed Limit” on Recovery after Mass Extinctions
Life Recovered Rapidly at Impact Site of Dino-Killing Asteroid
About 66 million years ago, an asteroid smashed into Earth, triggering a mass extinction that ended the reign of the dinosaurs and snuffed out 75 percent of life. Although the asteroid killed off species, new research led by The University of Texas at Austin has found that the crater it left behind was home to… Continue Reading Life Recovered Rapidly at Impact Site of Dino-Killing Asteroid
