Mesolithic inland Guangxi (Zengpiyan) people similar to Andamanese aborigines(?)

The paper addressed yesterday features some more potentially interesting information. See fig. 4 ("neighbour net splits tree generated from a Q-mode correlation coefficients matrix") of Matsumura et al. 2018.

Zengpiyan male skulls clustered closely with Fujian Tanshishan male skulls and more distantly with Guangdong Hedang male skulls in fig. 1 of Chen 1989. However, Zengpiyan female crania seem to have been outliers. Note though, the metric values to which she refers indicate a long average head and a more or less large average face in both sexes at all three locations. I.e., they were probably less gracile than present-day Andamanese aborigines, whose geographical isolation until recently and y hg profiles anyway indicate high probability of more increased gene drift.

Then again, Zhang Guangzhi associated Tanshishan with northerners according to Tsang Chenghwa. And fig. 4 of Matsumura et al. 2018 confirms hat Tanshishan people could have had relatively significant amounts of northern ancestry when compared with Zengpiyan people, who cluster with Andamanese and Bac Son people. Andamanese are moreover within a dendrogram cluster featuring Bac Son samples according to Matsumura et al. 2008, who examined tooth crown diameters. So there could be different clines with Mesolithic Zengpiyan people possibly having been relatively similar to the ancestors of present-day Andamanese.
