Sixty-six million years ago, a catastrophic asteroid impact wiped out75% of Earth’s species, bringing an abrupt end to the reign of the nonavian dinosaurs. The9-mile-wide (15 km)space rock struck what is now Mexico, unleashing firestorms, acid rain, and a global winter that...
What is intelligence anyway?If life is about survival of a species — and intelligence is meant to serve that survival — then we can't compare with pea-brained sea turtles,which were here long before us and survived the disaster that wiped out the dinosaurs.Still,it is comforting to realiz...
Theories of their demise point to Homo sapiens (us) outcompeting them for food and territory as the last ice age set in, which sealed the Neanderthals' fate. You may like What if a giant asteroid had not wiped out the dinosaurs? Neanderthals: Who were they and what did our extinct ...

It had its successes, but the extinction of species continued to spiral out of control: one Harvard biologist, E. O. Wilson, estimates that the extinction rate today is as high as it was during the great extinction that wiped out the dinosaurs 65 million years ago. What particularly worried...

Members of both groups have cartilaginous skulls, qualifying them as true crown-group vertebrates, but lack jaws. In fact, they are the only two groups of extant vertebrates that lack jaws. Are fish older than dinosaurs? Since the extinction event that wiped out the dinosaurs 66 million years...
