POSTILLONE, María B et al. LINAJES MATERNOS EN MUESTRAS ANTIGUAS DE LA PUNA JUJEÑA: COMPARACIÓN CON ESTUDIOS DE LA REGIÓN CENTRO-SUR ANDINA. Rev Arg Antrop Biol [online]. 2017, vol.19, n.1. ISSN 1514-7991.  http://dx.doi.org/10.17139/raab.2017.0019.01.03.

Archaeological records provide abundant evidence of an active interaction between the peoples of what are now northwestern Argentina, southern Peru, western Bolivia, and northern Chile. Likewise, DNA studies in prehispanic individuals provide direct information on the biological history and dynamics of human groups, offering new perspectives to the understanding of dispersion and variability of Native Americans. The aim of this paper is to analyze the maternal lineages present in individuals from the late period of the Puna region (1000-1450 AD) by comparing their genetic composition with other pre-Columbian groups from the south-central Andean region, described by other authors. From mtDNA HVR-I sequences, inter- and intra-sample genetic variability was determined, as well as the genetic distance between the various groups used. In the samples analyzed, A2 was found to be the most common lineage,, showing high haplotype variability, and contrasting with other studies in the Andean region, which described the prevalence of B2 lineages. At a local level, the genetic distances between the Puna population and other groups from presentday northwestern Argentina were not significant, except for Pampa Grande, which is more geographically and spatially remote. At a regional level, the differences are significant in relation to the majority of Peru ancient samples, but do not show a particular spatial or time pattern.
