The Power of Babel

It took me awhile to get through this book, but I found it very informative. I was interested in the subject because I recently read Everyone is African, a book about the common origins of all humans. That made me realize we must also have had a common language at one time, and so I looked for books on the evolution of language. My questions about the common language probably are unanswerable, but this book gave me an idea of how languages change, and how the common language would have changed.
