DNA cultural evolution book GRANDPA WAS A DEITY gets more hard data

We now, 15 years after GRANDPA WAS A DEITY was published, are getting more detailed data on the founders of western and Chinese civilization.
It comes in the form of a research paper The phylogenetic and geographic structure of Y-chromosome haplogroup R1a where the line we're interested in is shown in figure1, under branch Z93 sub-branch M780.

As with all my books over the past 40-years, it takes time for the research to fill in the grey areas and confirm the obvious.  In this case, eventually the connection will be made to the Hebrew Levite and, if we ever get proper data from China, to the founders of that civilization as well.
