Scientists discovered the skull fragments back in 2009, but have only this week published their findings in the Proceedings of the National Academy of Sciences. Features not found in any earlier specimens of the Homo genus, such as the absence of a brow ridge on the skull’s frontal bone, mark it as a modern human.
