The genome sequence of 7,000-year-old human remains overturns the popular image of light-skinned European hunter-gatherers, the Guardian reported.
The Spanish National Research Council (CSIC) took DNA from the tooth of a European hunter-gatherer. The Mesolithic man, who lived in Spain around 7,000 years ago, had an unusual mix of blue eyes, black or brown hair, and dark skin, according to analyses of his genetic makeup.
The Spanish research team started their work in the Cantabrian Mountains of northwest Spain in 2006. The human remains had been well preserved by the cool environment of the cave.
Details of the study were published in the journal, Nature.
