The Earth is now entering the sixth mass extinction event in its four-billion-year history, but what's different about this die-off is that this is the only such event precipitated by a biotic agent: humans. (Phys.org) -- It took some 10 million years for Earth to recover from the greatest mass extinction of all time, latest research has revealed.

By Charles Choi, LiveScience Contributor: Feverishly hot ocean surface waters potentially reaching more than 104 degrees Fahrenheit (40 degrees Celsius) may have helped cause the greatest mass extinction in Earth's history, researchers say . Some species are more critical than others in preserving the It is best known for the extinction of non-avian dinosaurs, but large numbers of plant species also became extinct at that time.
