33 generations go back more than 1000 yrs. Just where did those society members come from - their ancestors were who?
Just ONE pair of common ancestors, out of countless thousands, would result in millions of descendants by now...as the numbers more than double each generation coming back this way.
I have lines traced back well over a thousand years -
Do you think most generations have more than 30 years' age difference between mother and child? Fine, make it 1500 years. Unless you think women were still having children at age 45.
Just ONE pair of common ancestors, out of countless thousands, would result in millions of descendants by now...as the numbers more than double each generation coming back this way.
So? Explain how current inhabitants of two societies separated from each other for 1500 years are going to have any common ancestors within 33 generations (earlier I was assuming 30 years/generation, but I guess it's conceivable a society could theoretically have generations longer than that; I really doubt any society is going to have generations longer than 45 years).
