Identified drivers of the largest mass extinction in Earth history

Photo credit: CC0 Public Domain Life on earth has a long, but also extremely turbulent history. On more than one occasion, the majority of all species became extinct and an already highly developed biodiversity shrank to a minimum again, whereby the course of evolution changed each time. The most extensive mass extinction occurred around 252 million years ago. It was …

Switch to warmblood, triggered by the largest mass extinction in the world

The origin of endotherm in synapsids, including the ancestors of mammals. The diagram shows the development of the main groups through the Triassic, and the scale from blue to red is a measure of the degree of warm-bloodedness, which was reconstructed using various indicators of bone structure and anatomy.

Restoring farmland could drastically slow extinction and combat climate change

The double crises of climate change and the loss of biodiversity are intertwined: Storms and forest fires are intensifying, while up to a million species are threatened with extinction. The solutions aren’t small or simple, but they exist, say scientists. A global roadmap published in Nature on Wednesday shows a way to soak up nearly half of the carbon dioxide …

What is the first species that humans threatened with extinction?

Sometime in the late 17th century, in the lush forests of Mauritius, the very last dodo took its last breath. After centuries of carefree ferrets in the tropical undergrowth, this species found its premature end due to humans who arrived on the island less than 100 years ago. With a penchant for hunting, habitat destruction, and the release of invasive …

The newly discovered mass extinction sparked the beginning of the dinosaurs

Huge volcanic eruptions 233 million years ago pumped carbon dioxide, methane and water vapor into the atmosphere. This series of violent explosions on what is now Canada’s west coast led to massive global warming. Our new research revealed that this was a planetary mass extinction that killed many of the dominant tetrapods and heralded the onset of the dinosaurs. The …
