The findings were revealed ahead of a Channel 4 documentary, which tracked the ancient DNA project at the Natural History Museum in London as well as creating a new forensic reconstruction of Cheddar Man's head.
Prof Barnes and Dr Brace began working in the Natural History Museum's ancient DNA lab, where they drilled 2mm holes into the ancient skull.
That is, while scientists had previously thought that Europeans had pale skin tens of thousands of years ago, an analysis of Cheddar Man's DNA has proved that dark, nearly black skin was common at the time and that pale skin only came much later. A group of scientists from the London Natural History Museums carried out the work of reconstructing the face.
The 10,000-year-old fossil, known as Cheddar Man, was initially believed to have had fair skin and hair. The Daily Mail reader was hoping for any of the above when he opened today's copy, only to find the Cheddar Man staring back from page 3.
A research team analyzed genes that shed light on Cheddar Man's appearance and life-style. This population had lighter skin and brown eyes and would have absorbed populations like the ones Cheddar Man belonged to.
It is believed that pale skin probably arrived in Britain with a migration of people from the Middle East around 6,000 years ago.
Until recently, it was assumed that humans adapted to have paler skin shortly after entering Europe about 45,000 years ago.
In the 90s, scientists compared Cheddar Man's DNA with 20 living residents of Cheddar village and found just two matches, the reported. For the last century, scientists have hypothesized about where he came from and what he looked like.
Cheddar Man would have lived a hunter-gatherer lifestyle, making sharp blades from flints for butchering animals, useing antlers to whittle harpoons for spear fishing and carving bows and arrows.
"He reminds us that you can't make assumptions about what people looked like in the past based on what people look like in the present, and that the pairings of features we are used to seeing today aren't something that's fixed", said Tom Booth, a Natural History Museum archaeologist involved in the research. "To go beyond what the bones tell us and get a scientifically based picture of what he actually looked like is a remarkable achievement". "We are all immigrants", he said.
The story of Cheddar Man, in his 20s, 5ft 5in tall, and weighing 10st, is told in Channel 4's The First Brit: Secrets Of The 10,000 Year Old Man, on February 18.
