Homo Sapiens went through a set of mutations that were selected for his becoming a long-distance fast bipedal runner somewhere around 300,000 BCE. The collateral effect of these mutations was the possibility to increase the number of vowels and consonants produced by the Hominin phonatory apparatus Homo Sapiens inherited from his Hominin ancestors, Homo Erectus and Homo Ergaster. From maybe a couple of hundred calls, he jumped, due to the rotation of vowels and consonants, to several thousand items that became lexical items by being attached to referents (objects, actions, etc.) Homo Sapiens had already an advanced first articulation language when the first migration out of Black Africa to Egypt, North Africa, and the Sahara took place and it must have happened around 200,000 BCE since Homo Sapiens remains were found on Crete and were dated as going back to 160,000 BCE. This first migration gave the big family of languages known as Afro-Asiatic or Semitic. Check what I have published on the subject of the Language of Cro-Magnon in Amazon's Kindle Store.
