- Apr 5, 2014Why did the ancestors of clams and oysters flourish after one of the worst mass extinctions in Earth’s history while another class of shelled creatures, the brachiopods, sharply decline? By using fossils to calculate the food intake of both groups, scientists are one step closer
- Mar 29, 2014A new study shows that large predators roamed the oceans soon after the End-Permian extinction--suggesting that ecosystems recovered more rapidly than previously thought.
- Mar 27, 2014A new study reveals that an ancient food web was organized much like modern food webs--despite the 48 million years of evolution that separate them.
- Feb 28, 2014A Virginia Tech researcher has developed a new way to classify and name organisms based on their genome sequence.
- Feb 16, 2014An international team of scientists has produced global maps showing how fast and in which direction local climates have shifted.
- Feb 9, 2014A new study suggests that the sizes of organisms following mass extinction events may vary more than previously thought.
- Nov 22, 2013A new paper reveals how the worst extinction in Earth's history may have been tied to the formation of Supercontinent Pangea. The catastrophe wasn't triggered by an impact from above--unlike another well-known extinction--but by a geological process below, deep within Earth's core.
- Aug 31, 2013A new study shows that the closest ancient relatives of mammals not only survived the greatest known mass extinction in Earth's history, they also thrived in its aftermath.
