Forensic science used to determine who's who in pre-Columbian Peru
23 Apr 2012
Analysis of ancient mitochondrial DNA (mtDNA) has been used to establish migration and population patterns for American indigenous cultures during the time before Christopher Columbus sailed to the Americas. New research published in BioMed Central's open access journal BMC Genetics has used more detailed DNA analysis of individuals from Arequipa region to identify the family relationships and burial traditions of ancient Peru.
The social unit (ayllu) of Native South Americans is thought to be based on kin relationships. The establishment of ayllu-based communities is also associated with funereal monuments (chullpas) which are thought to be important social sites not only because of their religious importance but because they housed the venerated ayllu's ancestors. Ancestor worship and a belief in a common ancestor, central to the ayllu, still exists in the traditions of the Q'ero community.
