"absolutely nothing" ... like, not even an iota of correlation ... A book from 2006 - NOW THAT'S a source you can count on! But thousands of years of history, means "ABSOLUTELY NOTHING".
Thank you for that citation. Did you read the book? Do you know the author? Do you know why Wiki chose this particular author's opinion on this topic and not one of dozens of others that disagree with him on this point?
That's the problem with using wiki as a trusted source. It helps people with no knowledge on a subject, look at a random article on a complicated subject and claim it as a canon.
