Testing Jeanson's Model: Y Chromosome Mutation Rates

Then he’s saying he used his y-chromosome mutation rate to create a family tree, and then takes all of the males from the family tree to estimate population growth throughout history.

His curve matches the historians’ curve.

That is not a valid way to estimate population size, and it is frankly stunning if this is in fact what he did.
