> dhw: Please reread your own comment above, as regards human language not appearing until 50,000 years ago, though the anatomical changes were present 200,000 years ago. Now you are simply repeating what I said in my response above and in my initial response to the article you posted (new sounds gradually evolving into the complexities we know today), except that in the first quote above I suggested that the anatomical changes were the result of the need for new sounds - i.e. the organism responding to new requirements, as we see in the less complex process of adaptation.-'Needing new sounds' is fine, but the anatomic changes which occurred and are required for precise sounds, are a complex mix which require advanced planning to put together requiring many different mutations. But all we have from the fossils is punctuated equilibrium, which means saltation.
