The first sabre-toothed cat-like predator was not much larger than a bobcat, but it had long teeth and a strong jaw to cut through thick skin.
Birds will shriek and dive at each other over food, territory or mates, but only a small number of species sport actual weapons. The reason: Flying matters more for their survival than fighting.
Macaque tooth wear was identical to our ancestors, throwing into question the long held belief that tool use caused the markings on hominin tooth fossils.
New research sheds light on why predators don’t evolve to become so aggressive that they eat all their prey – and then go extinct themselves.
We’ll probably be less aggressive and more agreeable, but have smaller brains – a bit like a Golden Retriever, we’ll be friendly, but maybe not that interesting or bright.
How we’re linking together genetic material from thousands of people - modern and ancient - to trace our ancestors and the history of our evolution.
Hard and strong, or bendy and flexible? A cartilaginous skeleton provides advantages in the ocean, but wouldn’t stand up to life on land.
Research has revealed how earless moths manage to avoid bat attacks - by evolving sophisticated acoustic tricks.
Two newly discovered species of quokka-sized kangaroos, which lived 18 million years ago in the Queensland rainforest, show evolution in the act of giving kangaroos a taste for leaves.
You have a finely honed sense of privacy in the physical world. But the sights and sounds you encounter online don’t help you detect risks and can even lull you into a false sense of security.
In 1872, Charles Darwin published a book on expressions and emotions that modern science is only beginning to catch up with.
Assuming that natural selection shapes all animal and plant traits is a false impression. Natural selection is a mindless process.
To a group of hungry killer whales, a longline fishing boat looks like an all-you-can-eat buffet.
The lack of large numbers of fossils makes it hard to study sexual dimorphism in dinosaurs. But a new statistical approach offers insight into this question and others across science.
As climate change worsens, their findings highlight the importance of conserving natural river flows to enable freshwater species to respond and adapt.
How did penguins end up with so few bones – and become lightning-fast swimmers?
Darwin thought female animals were non-strategic and uniform, making similar decisions.
Sponges are ancient marine animals and have already shown robustness against stresses from climate change. New research now shows they can also tolerate low-oxygen conditions.
David Attenborough’s new BBC documentary The Green Planet shows plants are stranger than they first appear.
If you ever feel like you can’t stop eating sugar, you are responding precisely as programmed by natural selection. What was once an evolutionary advantage has a different effect today.
