Abstract

Previous aDNA research in the Southwest provides a framework to understand the Mimbres population which maintains a unique identity in the archeology of the desert Southwest of North America. Both the mitochondrial DNA (mtDNA) haplogroups and haplotypes of a sample of 46 Mimbres individuals were identified from skeletal remains and compared to those of other ancient and modern populations in the American Southwest and Mexico. The haplogroup frequency distribution of the Mimbres resembles that of other Southwestern populations, suggesting a close relationship between the Mimbres and the neighboring populations and population continuity for a long period of time. However, their relatively low frequency of haplogroup A (11% n = 5) is consistent with a clinal distribution of haplogroup A from Mesoamerica to the Southwest. Moreover, unlike other Southwestern populations, the Mimbres share haplotypes with populations to the south, such as the Cora, Huichol, and Nahua, suggesting gene-flow from Mesoamerica. Here we discuss this data in light of the origin of the Mimbres population and their relationship to other Southwestern and Mexican populations.

► We analyzed ancient DNA from 46 individuals from the Mimbres population in New Mexico. ► mtDNA haplogroup frequencies correspond with those from other Southwestern populations. ► Derived mutations in the HVSI of several samples are shared with Mesoamerican samples. ► This is possibly indicative of gene-flow with Mesoamerica in the desert Southwest.
