R-173 Coalescent Times (Kivisild, 2017)

This paper came out last week.  Nothing new, but this graph does give a good illustration of a cultural phenomenon affecting some of the R1 sub-clades at 5,500 years before now.

There has been astonishing uniformity in the paternal markers of diagnostic Corded Ware and Bell Beaker males thus far.  Regarding V88, one thing I will be watching for is if any of the 200 Beaker samples can be categorized in this group. 

The study of human Y chromosome variation through ancient DNA

  1. One of my main interests in studying Neolithic cultures is to see if there is any evidence for a Noah's flood type of event. As I understand it, Noah's flood(whether it was global, local, or there was just some world wide climatic events that gave rise to global flood myths) would have been about 2,350BC. There does seem to be some major decimation of Neolithic populations in the 2,350BC to 1,900BC time frames. Old kingdom Egypt came to an end and had a dark period for hundreds of years. The Indus Valley civilization is destroyed, it's cities abandoned and no cities are built again in India for hundreds of years. The Sumerians have a population collapse of about 97% and then the Akkadian Empire arises. I don't understand these genetic studies very well and whether they would be consistent or inconsistent with a Noah's flood type of event. Here is one study that seems to be consistent at least with European populations:

    1. The 4.2 kiloyear event corresponds with that period. There was a conference that looked at the various upheavals in the European context. I linked at least one paper in previous entries.

  2. Thanks for posting, its a nice summary ,but this is based on available handful of complete sequences , which are skewed mostly.
