mass extinction

If I had been given one wish as a child I, it would have been that the Tasmanian tiger wasn’t extinct. To me extinction was a tragedy. I expect that many people feel the same way. But it is not easy to save dwindling populations and prevent extinctions. Sure it takes money, but it also… Read more

Throughout the past 600 million years there have been five major mass extinction events that devastated life on Earth. While some of these events are very well studied, such as the killer asteroid that wiped out the dinosaurs 66 million years ago, others are more enigmatic and entertain a variety of possible causes. The first… Read more

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… Read more

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… Read more

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… Read more
