> Tony: Yes, but we have no EVIDENCE that the larynx dropped. Only speculation, a story based on the assumption that we were originally chimpanzees, whose larynx sits marginally higher than ours. That is my point. It is a story, a story with no evidence. The larynx bones of infants sit much higher than that of adults. So we KNOW that the bone migrates during development.-The evidence is indirect. In this website you can see how much higher our tongue and lips are from the larynx as compared to the ape. I realize you don't think we are directly related to apes in evolution, but I accept some sort of evolutionary process happened and the larynx dropped.-http://crankylinguist.blogspot.com/2010/10/chimp-vs-human-vocal-tracts.html-And this comment just for dhw:-"One last thought as I mount an old hobby horse of mine. This transition from chimpanzee vocal tract to human tract did not require just a generation or two. If you want to agree with the generativists and the archaeologists who argue that speech is at most only a hundred thousand years old, you must account for the fact that we had already gotten rid of our chimpanzee vocal tract. Perhaps it was a pre-adaption but please, tell us what led to its formation." (my bold)-http://www.babelsdawn.com/babels_dawn/2010/10/the-evolution-of-the-vocal-tract.html
