Tiny ‘Engineers’ Caused First Mass Extinction

We tend to associate mass extinctions with catastrophic events, like giant meteorite impacts and volcanic super-eruptions. The world’s first known mass extinction—about 540 million years ago— appears to have had a more subtle cause: evolution itself. Says Simon Darroch, assistant professor of earth and environmental sciences at Vanderbilt University: “People have been slow to recognize […]

Mass Extinctions Linked To Comet, Asteroid Showers

Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study. For more than 30 years, scientists have argued about a controversial hypothesis relating to periodic mass extinctions and impact craters, caused by comet and asteroid showers, on Earth. Michael Rampino, a New […]

Which Species Will Survive Earth’s Sixth Mass Extinction?

Scientists recently suggested that the Earth’s sixth mass extinction has begun. As terrifying as that sounds, surely humans are too smart and too important to get wiped out? Palaeontologists have long tried to shed light on this question by looking for general rules that might predict the survival of a species. While this is not […]
