Latest Extinction events Stories
While it has long been assumed plant and animal life took a long time to recover following the largest mass extinction to date, researchers from the University of Zurich have discovered new evidence to suggest they may have bounced back sooner than previously believed.
A mass extinction, wiping out numerous species including the dinosaurs, marked the end of the Cretaceous Period. A new study reveals that the structure of North American ecosystems made the extinction worse than it might have been.
Life about 250 million years ago was hard to come by. In fact, it was nearly non-existent. Scientists, studying why this period, known as the end-Permian event, lasted so long and have found a key ingredient: heat.
Geochemists from the University of California, Riverside teamed up with an international team of scientists to uncover new evidence linking together extreme climate change, elevation of oxygen levels and early animal evolution.
Disregard of three critical protocols explains why a group challenging the theory of a North American meteor-impact event approximately 12,900 years ago failed to find iron and silica rich magnetic particles in the sites they investigated.
Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet, but a new study indicates that a separate extinction came shortly before that.
Asteroid impact craters are found all over the Earth, but most are erased by erosion or covered by time. The date has moved a billion years back by the discovery of the oldest impact crater yet at 3 billion years old.
A basic tenet underpinning scientists' understanding of extinction is that more abundant species persist longer than their less abundant counterparts, but a new University of Georgia study reveals a much more complex relationship.
An asteroid impact may have ended the reign of the dinosaurs here on Earth about 65 million years ago, but new evidence suggests many of the large, plant-eating dinosaurs were already dying out during the last 12 million years of the Cretaceous period.
In a first of its kind study, researchers from Vanderbilt University found that mammals’ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes.
