Where did Earth's global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents' Professor in ASU’s School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has found an answer in a previously neglected source…

About 252 million years ago, more than 90 percent of all animal life on Earth went extinct. This event, called the “Permian-Triassic mass extinction,” represents the greatest catastrophe in the history of life on Earth. Ecosystems took nearly five million years to…
