Scientists are working to understand the cause and how the events of the LPME unfolded by focusing on mercury from Siberian volcanoes that ended up in sediments in Australia and South Africa. The ...

According to a new study published this week by researchers at the University of Illinois, a nearby star's supernova may've caused one of out planets mass extinctions millions of years ago. The event ...

(CNN) — No species lasts forever — extinction is part of the evolution of life. But at least five times, a biological catastrophe has engulfed the planet, killing off the vast majority of species from ...

Mass extinction events (MEEs), defined as significant losses of species diversity in significantly short time periods, have attracted the attention of biologists because of their link to major ...

A lethal pulse of ultraviolet (UV) radiation may have played a role in Earth's biggest mass extinction event, fossilized pollen grains reveal. Pollen that dates to the time of the Permian-Triassic ...

The late Devonian extinction is one of the five major extinction events to have occurred on Earth. It's not unusual for scientists to argue over what causes a mass extinction event -- of the five, the ...

The cause of the Devonian period extinction 359 million years ago, ranked as one of the five great extinctions of life on Earth, remains a mystery. Now, a new study reveals the explosion of a nearby ...

Researchers have gone back in time to find an extinction event that predates all other known events of their kind. The extinction event, which occurred during the Ediacaran Period roughly 550 million ...

A study has found evidence that the evolution of tree roots over 300 million years ago triggered mass extinction events through the same chemical processes created by pollution in modern oceans and ...

Dinosaurs ruled the Earth for over 150 million years. Compared to the mere 4–6 million years that scientists believe humans and their earliest ancestors have been on the planet, it wouldn’t be ...
