How did a single species of rodent invade South America and then quickly branch off into 350 new species?
The answer is simple -- the rodents were able to move quickly across the continent unencumbered by geographic boundaries that can't be easily crossed such as an ocean.
FSU Professor of Biological Science Scott Steppan and his former...
Amphibian biologists from around the world watched in horror in 2004, as the frogs of El Copé, Panama, began dying by the thousands. The culprit: Batrachochytrium dendrobatidis, a deadly fungus more commonly known as chytrid fungus. Within months, roughly half of the frog species native to the area went locally extinct.

Knowledge of the diet of people living in the prehistoric settlement of Çatalhöyük almost 8000 years ago has been completed in astonishing scope and detail by analyzing proteins from their ceramic bowls and jars. Using this new approach, an international team of researchers has determined that vessels from this early farming site in central Anatolia,...
