What really concerns me about this theory is what it implies for the 90% of the human race that isn't European. Since various human groups separated about 50,000+ years ago and consciousness is only 3,000 years old, when did they acquire consciousness? Were Native Americans and Australian Aborigines unconscious until taught to read and write? Are they still unconscious? I suppose this is probably dealt with somewhere in the book.
