Early language part 2

It is not just brain power that makes you able to communicate complicated sounds to others. The shape of the throat and position of the tongue play a large, if not greater part in this. It is for that people think that later hominids, such as Neanderthals made much, more simpler sounds than our own. Contradicting this, a hyoid bone, a bone near the larynx and thus to do with speech found Israel, was found to be almost exactly identical to our own. The current theory is that they made quite high-pitched sounds, contrary to the popular low-grunting theory. Even with all this, they would not have spoken like us. Their tongue was positioned higher in the mouth and the pharynx, another part to do with speech was longer. Also the larynx, yet another part of the body to do with speech was slightly higher in the throat, and the nasal cavity was slightly different from our own.

Most researchers agree that trully modern speech appeared only with early modern man, but they can't agree on when. Some think 40,000 years ago, others disagree.
