The 2014 study was the first to analyze a pre-agricultural European genome. It was led by Inigo Olalde of the Institut de Biologia Evolutiva in Barcelona and published in the journal Nature – providing significant insight into the appearance of modern humans before farming arose in Europe.
The tooth came from the skeleton of a Mesolithic man who was found in a Cantabrian cave near León in northwest Spain, in 2006. It took several attempts before the team of scientists managed to recreate the full genome from the DNA of a wisdom tooth root. When they finally did, they were shocked. Dr. Carles Lalueza-Fox from the Institute of Evolutionary Biology in Barcelona explained the first of the fascinating discoveries made by the researchers:
“The biggest surprise was to discover that this individual possessed African versions of the genes that determine the light pigmentation of the current Europeans, which indicates that he had dark skin. You see a lot of reconstructions of these people hunting and gathering and they look like modern Europeans with light skin. You never see a reconstruction of a Mesolithic hunter-gatherer with dark skin”.

MASSACHUSETTS, United States, Monday April 13, 2015 – The findings of genetic research conducted at Harvard University have indicated that when early humans migrated north from Africa around 40,000 years ago, they retained their dark skin colour far longer than had originally been thought.
It was not until the first farmers migrated from the Near East through Turkey about 7,800 years ago, that two key genes that provide lighter skin appeared.
“We find a surprise in seven Scandinavian hunter-gatherers from the Motala site in southern Sweden who lived around 7,700 years before present.
The researchers found five genes associated with changes in diet, body size and skin pigmentation that underwent natural selection in the past 8,000 years.
Two of the genes – SLC24A5 and SLC45A2 – were associated with producing light skin.
The remains of early hunter gatherers who lived in Spain, Hungary and Luxembourg around 8,500 years ago lacked these key gene variants, the scientists found.
The remains of hunter gatherers that had lived in Motala, Sweden, 7,700 years ago, nevertheless carried both variants of SLC24A5 and SLC45A2 that produced lighter skin, as well as another gene known to produce blue eyes in Europeans.
