Ichthyosaurs were ocean-dwelling predators that lived alongside dinosaurs in the Mesozoic Era from around 250 million

Scientists have spent the past 30 years carefully tracking evolution across more than 68,000 generations of E. coli bacteria – the equivalent of more than 1 million years of human evolution. The latest results suggest we might have been wrong about one of the fundamental aspects of how species evolve.   Traditionally, researchers predicted that the

For the first time, researchers have documented the violent clash of predators from two very different worlds, discovering evidence of alligators feasting on sharks in the wild. While there have been anecdotal reports of this kind of thing happening before, it’s never been comprehensively studied, since ordinarily the American alligator (Alligator mississippiensis) and sharks occupy
