Researchers pieced together evidence from fossils that had been sitting in museums for years.
An artist’s impression of an ancient, 100% African sea cow.
Sea cows (Sirenia) descended from four legged mammals that roamed Africa when this continent was isolated. They belong to the Afrotheria, the 'African beasts'.
Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
A new fossil study challenges 130 years of thinking about how dinosaurs evolved.

Tubular fossils believed to represent early microbes.
Tiny tubes and filaments of iron found in rocks in Canada turned out to be the remains of microbes from over 3.7 billion years ago.

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.
Alfred the aetiocetid had teeth but needed a better way to capture his tiny prey.
The largest animals on the planet - the baleen whales - prey on some of the smallest. But how did their teeth evolve into the filters they use today?
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.

Next time you bite down on something you're eating, spare a thought for the evolutioniary leap made by an ancient fish that gave rise to our jaws.
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?
