COCILOVO, José A.; VARELA, Héctor H.; FUCHS, María L.  and  VALDANO, Silvia G.. MOBILITY, SOUTH ANDEAN TRAFFIC AND GENETIC DIFFERENTIATIONBETWEEN SAN PEDRO DE ATACAMA AND PUNA DE JUJUY. Relaciones [online]. 2017, vol.42, n.2, pp.1-10. ISSN 0325-2221.

The relationships between San Pedro de Atacama (SPA, 400-1535 AD) and Puna de Jujuy (PJ, 1029-1497 AD) are evaluated for their possible influence on the genetic structure of both populations. Frequency distributions based on phenotypic traits exhibit composed of individuals of both intermedíate zone subregion. The 8% of individuals of SPA were assigned in PJ with high probability (p=0.69), mainly from sites of the Middle and Late periods (Quitor 6, Coyo Oriental, Quitor 5, Quitor 1 and Yaye), and 32% of individuals of PJ (p=0.74), mainly from sites Doncellas and Agua Caliente, were assigned to the Early, Middle and Late periods of SPA. Evidence from the Fst statistic suggests the effect of mid- and wide-range migratory events influencing the balance between genetic drift and migration. The results are consistent with the relationships established by archaeology.

Keywords : caravans - traffic - exchange - genetic relationships.
