Kebara cave ~ 60 tya discovered 1986, origins of language, hyoid shape (hasn"t changed) . Post skeletal differences due to robusticity, same manual dexterity/posture/range/movement . Biggest difference = cranial morphology (1250-1650 cc) overlapped/larger than ours . 1997 dna test significantly different than ours = not direct ancestor split from us 600 tya . Grip tool with teeth while making it, flake tools, scraper/hand axe, 1st hominoid to haft stone points . Levallois technique 200 000 years old, symmetry = enhanced cognitive ability .
