Bipedal movement has existed in modern reptiles for much longer than we previously knew.
Little skates that 'walk' across the ocean floor show how fish brains evolved to pave the way for working legs.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
This new research offers compelling proof that the naysayers were right. "Mrs" Ples was actually a "Mr".
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.
New discoveries are changing archaeologists' ideas about the origins of our own species and our migration out of Africa. This fossil pushes Homo sapiens' African exodus date back by 50,000 years.
Lepidoptera insects are at least 70m years older than we previously knew.
As a new David Attenborough documentary examines a remarkable fossil, a leading expert gives his verdict.
Fossilised bones discovered in New Zealand reveal an extinct penguin which may have been the largest to ever live, around the same height as an average man.
Scientists in New Zealand have discovered an extinct penguin known as Kumimanu biceae that was 1.77m tall.
Researchers in human evolution used to focus on Africa and Eurasia – but not anymore. Discoveries in Asia and Australia have changed the picture, revealing early, complex cultures outside of Africa.
'Marsupial lions' aren't really lions - but they did have teeth that formed a pair of secateur-like blades. The newly found species lived in forests of Queensland around 20 million years ago.
Researchers use CT scanners to take first look inside pterosaur eggs.
Scientists can be overly thirsty for dinosaur blood.
One animator combined his skills with paleontological evidence to breathe movement into a dinosaur fossil to eye-catching effect.
Reconstructing the colours of the feathered Sinosauropteryx gives hints about its habitat and lifestyle.
Recent research suggests that humankind's origins lay outside of Africa. This is the nature of science: a paradigm that cannot be questioned on a regular basis becomes a dogma.
Until this discovery, theropod dinosaurs were thought to be considerably smaller, at three to five metres in body length, during the Early Jurassic.
Maeve, age 8, has a question that has stumped many scientists over the years. And that’s because it’s a surprisingly tricky question to answer. It depends a bit on what you mean by 'person'.
Bones and texts showed how decades of strenuous hikes led to higher levels of osteoarthritis in workers' knees and ankles in an ancient Egyptian village.
