Recently, DNA from the wisdom tooth of a hunter-gatherer in a cave in Spain was analyzed and the data revealed some interesting new finds. The man exhibited a darker toned skin, although the exact shade is unpredictable due to many environmental factors. This is surprising, because it was thought that the Europeans of this time has already developed lighter skin. Furthermore, the man has blue eyes. The blue eye gene wasn’t thought to have developed for some time after this man lived. In many respects the analysis of this caveman’s DNA has changed the way we view people from the Neolithic time period.
