A 245m year old fossil is the first evidence that of live births in one of the major groups of animals.
All primates have opposable thumbs – and some flaunt these in the cutest way.

Much like the hair you carefully rearrange before a selfie, your cheek muscles and the accompanying smile date back about 250 million years.
The author’s backpack was hiding this almost complete therapsid fossil. Was finding it all down to luck?
Good science isn't rooted in chance. It's based on people with expertise being in the right place at the right time, equipped with enough knowledge to know what they're looking at.
How our ancestors ate could explain why today’s humans are mostly right-handed.
The way early humans learned to handle food could explain why the majority of people today are right handed.

The Natural History Museum's 'Dippy' the diplodocus skeleton is about to be become a giant 3D jigsaw.
A set of fossils that lay forgotten in a museum are revealing new secrets about Britain's prehistoric wildlife.

Mammals' ancestors had a third eye and the fossil record of its disappearance tells us the story of the evolution of one of our most important features: warm blood.
A 133 million-year-old fossil hints that dinosaurs had bigger brains than we've realised.
Savannasaurus was pretty small, by titanosaur standards.

Dinosaur bones unearthed at one of Australia's richest fossil sites have introduced us to a new species: Savannasaurus, one of a family of huge dinosaurs that trekked here more than 100 million years ago.
Cave artists knew about the elusive bison some 17,000 years ago.
DNA analysis suggests that a newly discovered species of bison roamed Europe some 17,000 years ago - as prehistoric cave artists were trying to tell us all along.
Were legs a quirk of genetic mutation rather than an evolutionary inevitability?

An old technique to explore the inside of fossils unfortunately ended up destroying some unique specimens. New technology has been used to reconstruct one such fossil.
This skull belongs to the carnivorous gorgonopsian therapsid Smilesaurus ferox which lived 255 million years ago.

Modern sabre-tooth mammals have their canines constantly on display. This allows them to seduce mates. But was sexual selection also an important phenomenon among our pre-mammalian ancestors?
The earliest hominin cancer.

Cancer is not the modern disease many believe it to be. New fossil evidence from two South African caves suggests that its origins lie deep in prehistory.
If life survived on Earth 3.7 billion years ago, why not elsewhere in the solar system?
Scientists say they've found fossils showing life existed on Earth 3.7 billion years ago. How good is the evidence? And what does it mean for the search for life elsewhere in our solar system?
An exciting discovery suggests small pterosaurs weren't forced out by the rise of birds.
A living coucal from South Africa, whose huge prehistoric relatives lived on the Nullarbor.
The Nullarbor is an arid, treeless expanse today. But several hundred thousand years ago it was home to a menagerie of species, including two newly discovered giant cuckoo-like birds.
A replica of a Homo naledi skull.
New evidence suggests that Homo naledi didn't deliberately deposit their dead in a hidden chamber.
The Australian lungfish has a bigger brain than you might think.
To understand how some creatures evolved, you need to see how their brain developed over millions of years. That's now possible thanks to some clever use of scanning technology.
