Non Potluck: aDNA study of pre-Hispanic South American populations

A recent study in AJPA used aDNA to examine haplotype composition in Andean populations.  They compiled autosomal, mitochondrial and Y-chromosome data from 8 groups identified during the Regional Developments Period (900-1430 AD). 19 individuals across 7 archaeological sites were compared.  This was a very interesting phylogeographic study that found individuals clustering into pre-Inca and Inca groups, regardless of geographic location.  It was also intriguing because both maternal and paternal lineages were predicted using the mitchondrial and Y-chromosome data.
