Unformatted text preview: MRE predicts ancestor of at least 400,000 ybp Test via mitochondrial DNA (mtDNA) “genetic clock” located in mitocondria Maternally inherited DNA Recent hominin dispersal: Bering Strait Oldowan- flakes, smashing and defleshing Acheulean- worked on 2 sides. Ex. Hand ax Mousterian- flaking more defined, core often flaked. Flakes sharpened as well, could be resharpened. Upper Paleolithic blade tools- eaten with, sharper, more of a range...
