How survivors spanned the globe after Earth's biggest mass extinction

Stanford Scientists Crack 252-Million-Year-Old Biodiversity Mystery

Stanford scientists found that dramatic climate changes after the Great Dying enabled a few marine species to spread globally, leading to worldwide biological sameness. Scientists don’t call it the “Great Dying” for nothing. Around 252 million years ago, more than 80% of all marine species disapp

How survivors spanned the globe after Earth's biggest mass extinction

Scientists don't call it the "Great Dying" for nothing. About 252 million years ago, upward of 80% of all marine species vanished during the end-Permian mass extinction—the most extreme event of its kind in Earth's history.

Violent Supernovae Triggered At Least Two Earth Extinctions

Eddie Gonzales Jr. – MessageToEagle.com – At least two mass extinctions in Earth’s history were likely caused by the “devastating” effects of nearby supernova explosions, a new study suggests. Keele University researchers say these powerful blasts, from the death of a massive star, may have stripped Earth’s atmosphere of ozone, caused acid rain, and exposed […]

The diversification of viruses in the waters of Lake Tanganyika 2 to 3 million years ago could be linked to a supernova whose traces have just been identified by the team led by Caitlyn Nojiri of the University of California (UC) Santa Cruz. "The effect of supernova...
