CARDOZO, Darío Gonzalo et al. Impact of the hispanic conquest at the lower Parana wetland (Argentina). An historical and mitochondrial genetic perspective. Runa [online]. 2021, vol.42, n.1, pp.409-433.  Epub Apr 21, 2021. ISSN 1851-9628.  http://dx.doi.org/10.34096/runa.v42i1.7994.

In order to investigate the genetic impact that the Hispanic conquest would have generated in the native groups settled in the Middle and Lower Paraná, samples of pre and post-Hispanic individuals of this region were analyzed. Mitochondrial DNA haplogroups were identified using restriction fragment length polymorphism (RFLP). The data were compared with those from other pre- and post-Hispanic archaeological sites and with contemporary samples. We observed a higher prevalence of native B haplogroup, in the post-Hispanic samples, without significant difference with the pre-hispanic group of the lower and middle Parana region. Both groups present similar haplogroup frequencies of those found in samples from Gran Chaco and the Córdoba province. This corresponds with archaeological data and the documentary sources about the Santiago del Baradero reduction (Buenos Aires province), with the prohibition of the departure of women from the reduction and the shortage of foreigners
