Prehistoric climate change damaged the ozone layer and led to a mass extinction, study finds

Mass extinctions are very important to how life evolved on Earth. For example, when an asteroid hit the Earth 66 million years ago, the resulting dinosaur extinction led mammals to take their place. My colleagues and I have published new research on the mass extinction that took place 359 million years ago at the boundary between the Devonian and Carboniferous geological periods. There have been many previous speculations as to the cause of this event, including volcanic eruptions, asteroid impacts, climate change, sea level changes, wildfires and the rise of the first forests. But we have shown that the extinctions…
