    Neanderthal Woman's Genome Reveals Unknown Human Lineage

    The existence of a mysterious ancient human lineage and the genetic changes that separate modern humans from their closest extinct relatives are among the many secrets now revealed in the first high-quality genome sequence from a Neanderthal woman, researchers say.

    The Neanderthal woman whose toe bone was sequenced also reveals inbreeding may have been common among her recent ancestors, as her parents were closely related, possibly half-siblings or another near relation.

    7,000-Year-Old Human Bones Suggest New Date for Light-Skin Gene

    [​IMG]

    An ancient European hunter-gatherer man had dark skin and blue eyes, a new genetic analysis has revealed.

    The analysis of the man, who lived in modern-day Spain only about 7,000 years ago, shows light-skin genes in Europeansevolved much more recently than previously thought.
    The findings, which were detailed today (Jan. 26) in the journal Nature, also hint that light skin evolved not to adjust to the lower-light conditions in Europe compared with Africa, but instead to the new diet that emerged after the agricultural revolution, said study co-author Carles Lalueza-Fox, a paleogenomics researcher at Pompeu Fabra University in Spain.

    ... Now comes the theory:facepalm:





    DNA Of Ancient Human Spawns New Theory Of Why Europeans Became White


    The Mesolithic period, or Middle Stone Age was followed by the Neolithic era, when hunter-gatherers became farmers and started eating a lot more grains.
    This dietary switch could be the reason Europeans developed lighter skin.
    "In the food-production theory, the cereal-rich diet of Neolithic farmers lacked vitamin D," LiveScience explains, "so Europeans rapidly lost their dark-skin pigmentation only once they switched to agriculture, because it was only at that point that they had to synthesize vitamin D from the sun more readily."
