A drying climate and the arrival of people together finished off Australia's megafauna.
300,000 years ago, there were lots of different species of human. Now it’s only us – and we're probably the reason why.
Populations of plankton are in decline. If we push this critical foundation of the marine food chain to extinction, we could cripple ecosystems for millions of years.
Every cloud has a silver lining – even the debris cloud from an asteroid impact
The island of New Guinea is home to 6% of the world’s frogs, but if the deadly chytrid fungus invades it could cause a mass extinction.
A new movie highlights the importance of radical hope and courageous action in responding to the climate crisis
Alarm bells went off when several recent studies reported mass insect die-offs in different parts of the world. But reports of an 'insect apocalypse' have been greatly exaggerated.
Australia is losing mammals faster than any other country, as well as plenty more plants and animals besides. Extinction is theft from future generations – it's time to treat it as such.
More evidence that the asteroid hit on Earth that marked the end of the dinosaurs could have triggered a deadly increase in volcanic activity.
Local tetrapod biodiversity exploded after the dinosaurs, but has barely changed in 60m years.
The natural world depends on insects to function, but they may be the next casualty of climate change.
Climate change threatens to cause mass extinctions – but how, exactly? New research suggests male fertility may be the weakest link.
The movement to kickstart a radical transformation of our society has begun. For the sake of our children – and their children – it must succeed.
Lee's research identified the cause of mysterious and devastating mass frog extinctions that spread across the world starting in the 1970s: it was a skin fungus.
Death is inevitable for individuals and also for species. With help from the fossil record, paleontologists are piecing together what might make one creature more vulnerable than another.
The Earth is losing more and more biodiversity every day, and we should all be worried
A new study of an ancient fossil has found it to be the earliest lizard known, so far. It shows they survived one the greatest mass extinctions on Earth.
New research shows that ground-dwelling birds were more likely to survive the mass extinction at the end of the Cretaceous period.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
Small asteroids can be hard to spot. But what kind of threat do they pose to the Earth?
