The historical record is full of surprises – and it could encourage conservationists to think more creatively.
The risks to nature from man-made global warming – and the imperative to act – are clear.
The analysis suggests that there was a mass extinction event at the time of the end-Permian, on land - and that it happened at the same time as the marine end-Permian extinction.
300,000 years ago, there were lots of different species of human. Now it’s only us – and we're probably the reason why.
The more we know about the animals that lived during this time, the more we can start to comprehend how species react and recover after an extinction event.
Growing evidence suggests that the extinction of the dinosaurs involved profound, complex and interconnected changes to the global systems that support life. Much like we are facing today.
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.
When environmental needs outstrip government funds, people power steps up.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
Scientists believe since 2010 we have entered the sixth period of mass extinction. CO2 emissions will change the lives of plants and animals in the next three to four decades.
The planet has seen five 'mass extinctions' over the past half billion years, but each was followed by an explosion in biodiversity.
Are we in the middle of a mass extinction caused by Homo sapiens? Past events can help us to understand the current crisis.
Mercury found in prehistoric rock bolsters the idea that volcanoes caused a mass extinction 200m years ago.
The Noril’sk nickel deposits In Russia are unique: giant volcanic eruptions 250 million years ago released colossal amounts of nickel into the atmosphere, kickstarting the Great Dying.
A geomagnetic reversal may have a severe impact on humans.
The jury is in and the debate is over: Earth’s sixth great extinction has arrived.
Large asteroid hits on Earth have the potential to wipe out humanity so knowing how to detect and deflect them is vital. But we know very little about the interior make up of many asteroids.
Human activity doesn't just reduce biodiversity – new research explores how we are continually creating new species and ecosystems, too.
New study supports the idea that an asteroid, rather than climate changes, caused the mass extinction that wiped out the dinosaurs.
Carbon dioxide is rising faster than any time in the past 66 million years. Rapid rises in the past have been linked to mass extinctions.
