But McC describes how H. erectus might have spoken, based on the fossil record. A key point is the drop in the larynx to its much lower position requiring a trap door (epiglottis) to prevent fatal choking. Our view of evolution is that it looks for simple safe solutions. This one created a great danger, and then solved the created problem. As a result we can have very precise complex speech.-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.

What is the purpose of living? How about, 'to reduce needless suffering. It seems to me to be a worthy purpose.
