The findings suggest we weren’t the first advanced carnivore among the hominins, as has been previously assumed.
Any hominid fossil find with molar teeth can be plugged into a new equation that reveals its species’ prenatal growth rate.

Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.
The evolutionary loss of body hair made it easier for human ancestors to hunt in the heat.

The human Y chromosome could disappear over time, putting our species in jeopardy. But some rodents have managed just fine without it – and we now know how.
Ajnabia odysseus lived 66 million years ago, making it one of the last dinosaurs on Earth.

New genetic research shows humans’ famed ability to adapt our behaviour and develop new tools and techniques has not always been enough to survive when times have grown tough.
The findings come from placoderm fish fossils found in Western Australia’s Kimberley region. This extinct order of fish represents some of our earliest jawed ancestors.

As early modern humans spread across the globe, their gut microbes genetically changed with them. Understanding the origins of gut microbes could improve understanding of their role in human health.
Cutting-edge analysis of fossil ape teeth reveals ancient seasonal change in Africa, long before human ancestors appeared. The method will be crucial for the future study of early hominins.
Humans are the only animals that express their thoughts in full sentences.
