Query: There's Babel in the Power of Babel

Thought this would be an interesting read but barely got past the introduction before consigning it to the recycle bin.First of all, the author's comments on evolution and mutations have been overtaken by important new discoveries. There's much more involved than just mutations. Second, the author states several times as fact that there once existed a single language possessed by the humans who migrated out of Africa to populate the world. I don't question the migration but the idea that there once existed a single spoken language used by all living humans is absurd. This idea implies, and the author directly implies this idea since he states it several times, that a single mutation brought the human power of speech into existence. Although I'm not going to attempt to provide any proofs here, the development of human language must have been a progressive process taking unknown hundreds of thousands of years to reach its full powers as we know of it today.
