The face of a 10,000-year-old British skeleton nicknamed "Cheddar Man" has been revealed after research carried out by a team of scientists at London's Natural History Museum.

The team, which specialises in evolution and DNA, worked with model-makers and professors at University College London to build a picture of what the man behind the skeleton would actually have looked like. It was found in Cheddar Gorge, Somerset back in 1903, hence the name.

Here's the skull of Cheddar Man:

And here's the reconstruction:

“Cheddar Man is one of the oldest human specimens that we’ve worked with, and yet the preservation of DNA has been good enough to recover huge amounts of information about his appearance and ancestry," said Professor Ian Barnes, Research Leader in Ancient DNA at the Natural History Museum, in a press release sent to Mashable.

The method used to recreate Cheddar Man's face is pretty complicated and science-y, but in a nutshell it went something like this: scientists obtained some bone powder by drilling into the skull, which contained enough genetic info to allow them to reconstruct the face; 3D printing technology was then used to construct the head pictured above.

“I first studied ‘Cheddar Man’ more than 40 years ago, but could never have believed that we would one day have his whole genome – the oldest British one to date!" said Professor Chris Tringer, Research Lead in Human Origins at the Natural History Museum.

"To go beyond what the bones tell us and get a scientifically-based picture of what he actually looked like is a remarkable (and from the results quite surprising!) achievement.”

Channel 4 are releasing a documentary about Cheddar Man and the reconstruction titled 'First Brit: Secrets of the 10,000 Year Old Man'. It airs Sunday 18 February.

Doing it with puters is infinitely less interesting to me than the guys that do it with clay.

Since when do they read DNA to know if someone was brown, anyway?

There are genes known to be important for the production of melanin and other pigments.
