A high handed way to look for speech. Or perhaps a back handed way. It appears that Neanderthals were right handed in general. Since the right hand is controlled by the left brain motor strip, and speech is over there also, there must be speech. The position of the larnyx (lower), arch of the palate (higher)analysis of tongue muscles are much more to the point. Book: The Ape That Spoke,John McCrone, 1991. McCrone makes a blanket statement that Neanderthals had speech. He think H. erectus had some rudiments, 1.5 million years ago.-http://phys.org/news/2012-08-neandertal-right-handedness-hinting-language-capacity.html
