DNA suggests 10,000-year-old Brit had dark skin, blue eyes

This full facial reconstruction is based on the skull of Britain's oldest complete skeleton, who was found in Cheddar Gorge in southwest England in 1903.

LONDON (AP) — DNA from a 10,000-year-old skeleton found in an English cave suggests the oldest-known Briton had dark skin and blue eyes, researchers said Wednesday.

Scientists from Britain's Natural History Museum and University College London analyzed the genome of "Cheddar Man," who was found in Cheddar Gorge in southwest England in 1903.

Scientists led by museum DNA expert say analysis indicates he had blue eyes, dark curly hair and "dark to black" skin pigmentation.

The researchers say the evidence suggests that Europeans' pale skin tones developed much later than originally thought.

"Cheddar Man subverts people's expectations of what kinds of genetic traits go together," said Tom Booth, a postdoctoral researcher at the museum who worked on the project.

"It seems that pale eyes entered Europe long before pale skin or blond hair, which didn't come along until after the arrival of farming."

"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," Booth said.

It's thought ancient humans living in northern regions developed pale skin because it absorbs more sunlight, which is needed to produce vitamin D.

Cheddar Man shares a genetic profile with several other Mesolithic-era individuals found in Spain, Hungary and Luxembourg whose DNA has already been analyzed.

The group, known as Western Hunter-Gatherers, migrated to Europe from the Middle East after the last Ice Age, about 12,000 years ago.

Dan Bradley, a professor of population genetics at Trinity College Dublin, said the findings were credible.

"There are other data from hunter-gatherers who lived in western Europe, and they also show darker skin and light eyes, blue eyes," said Bradley, who was not involved with the study.

"Modern Europeans are a mixture of people like this, who are older hunter-gatherer inhabitants of western Europe, and people who came in with the advent of agriculture, and people who came from the east in the Bronze Age and who also brought new genetics into the region."

Cheddar Man is the oldest complete skeleton found in Britain.
