Hunter gatherer genome
A 2014 study in Nature has shown that a 7,000-year-old Mesolithic hunter-gatherer found in Spain had dark skin and blue-eyes.
In 2006, hikers accidentally discovered the remains, along with another skeleton, in the Cantabrian Moutnains of Northwest Spain.
The remains of two males were found in a narrow, labyrinthine cave.
Though one of the mens' skeletons was too degraded to analyze, the team sequenced the genome of the other one, whose skeleton is shown here.
The team found the manwas genetically closer to Northern Europeans than to Southern Europeans and lacked the European mutation that confers lighter skin.
Teeth and skull
