mtDNA V7 in Dr. Knipper’s “Female Exogamy and Gene Pool Diversification”

The full title of the article is Female exogamy and gene pool diversification at the transition from the Final Neolithic to the Early Bronze Age in central Europe published 19 September 2017.

One day I was looking at my grandmother’s submission to mitochondrial haplogroup V7 on and noticed three “Germany-ancient” samples credited to Dr. Knipper; that’s how I found her article.

It is interesting because she and her research team extracted isotope ratio data to determine whether the individuals were local or non-local to the site, in addition to genomic data from the samples found.

The three V7 individuals are from the Königsbrunn, Obere Kreuzstraße (OBKR) site.

From Knipper et. al 2017 “Female Exogamy and Gene Pool Diversification”. the three V7 individuals were found at the Konigsbrunn-OBKR site in Bavaria, Germany.

I’m not exactly sure of the ages of the samples, but they were labeled Early Bronze Age by the research group.  I wondered if Dr. Knipper and her group considered the V7 samples local or not, so I emailed her to ask.  She is really nice and helpful by the way!  I was nervous because I’m not very familiar with anthropological terminology and was concerned about asking something that might be very obviously stated in the article for those who are familiar with the terminology.

We exchanged a few emails and she gave me permission to paraphrase her answer:

Based on strontium and oxygen isotope ratios found in their teeth, the V7 individuals are considered local by the research group, and were found in the Lech River Valley, Bavaria, Germany. Dr. Knipper did, however, say we can’t be 100% sure they are local because there is a possibility the isotope ratios happen to appear local by chance since the ratio is not exclusive to this area.

Additional note: There was an older paper with a different V7 individual found related to the Novosvobodnaya Culture.  I remember the big splash that paper made when it was published.  Professionals, please weigh-in on the two findings and their implications on the geographical origin of haplogroup V7, please!
