     A study published recently in Nature claims that Skeletal remains from a 7,000 year old Spaniard have been genetically sequenced and suggests that the evolutionary onset of light-colored eyes predates light skin.
     The remains were discovered in northwestern Spain at the La Braña-Arintero site. The skeleton belonged to a man from the Mesolithic Period who has been dubbed La Braña 1. One of his teeth yielded enough DNA to complete a genetic analysis. The results gave important clues about the evolution of appearance in the region.
     Though the height and approximate age at time of death were not released, the researchers were able to determine that La Braña 1 did not look quite how they expected. His dark hair and dark skin were not unusual, but he likely had light eyes which was very unusual for this time period. The exact shade of his eyes could not be determined, but it was clear to the researchers that they were not brown. This could very well mean that light eyes made their evolutionary debut before light skin.
     Another male skeleton, named La Braña 2, was also discovered by the team in 2006. Unfortunately, the DNA was not as well preserved in this second individual, which is making it difficult for the researchers to sequence. They are currently working to restore the genome and provide more information about what the earliest Europeans looked like during the Mesolithic Period.
