Resumen
Descripción general del contenido del recurso.
We present the first results of the genetic characterization of the ancient population that occupied the current territory of the Province of Córdoba (Argentina) through the study of mitochondrial DNA haplogroups from archaeological samples belonging to different cultural, geographic and temporal contexts. Of the 44 bone and tooth samples analyzed, 35 could be characterized unambiguously. The distribution of haplogroups observed in the archaeological sample differs significantly from that observed among the contemporary inhabitants living in the same region and presenting native maternal lineages. This is true whether the variation is evaluated through with the Exact Test or with the Nsitu program, that takes into account a number of evolutionary variables (drift, gene flow, number of generations and population size fluctuations). It is possible to observe in the course of time a gradual increase in the proportion of haplogroups C and D and a concomitant decrease of A and B, a trend already present in a subsample of intermediate age (with an average age of 562 years BP). That is, the above pattern reflects not only the profound population rearrangements resulting from the Conquest and its aftermath, but appears already in late pre-Hispanic times. Geographic variation in the distribution of haplogroups shows some clear differences, though they are not statistically significant due to the small sample size. The subsamples Sierras and Llanura (plains), with a similar average age, differ particularly in the incidence of haplogroup B, being verycommon in the first and almost absent in the second.
