The Denisovans, a mysterious group of ancient humans originally identified purely from DNA, finally have a face

Humans first arrived in South America through a series of extraordinary migrations – and genetic studies now reveal more about how they settled and then split into four distinct groups on the continent

As our ancestors developed more advanced tools and cultural practices, they also developed new ways of explaining concepts to others – culminating in the emergence of complex language

For the first time, we have a method for extracting proteins from preserved soft tissues like brains – which could be a treasure trove of evolutionary information

It’s natural to associate wild flights of fantasy with children and a more mundane internal world with adult life. The latest research, though, shows that isn't the whole picture

Teeth are good for chewing and biting, but they are also sensitive – and that may have been their original function hundreds of millions of years ago

Clues are emerging about the ghostly clan that settled eastern Asia and left a genetic legacy in people today

We now have full genome sequences for six species of apes, helping us to pin down our last common ancestor – and potentially changing how we think of the earliest hominins

Rather than simply keeping children away from social media, we need a specially designed option for them. This is how it should look.

The origin of complex eukaryotic cells, of the type found in all plants and animals, is shrouded in mystery. Now, strange microbes from wetlands in China are helping us to understand when they first emerged, and what they were like
