Objectives: To analyze the mitochondrial diversity in three admixed populations and evaluate the historical migration effect of native southern population movement to Santiago (capital of Chile). The intensity of migration was quantified using three mitochondrial lineages restricted to South-Central native groups.
Methods: D-loop sequences were genotyped in 550 unrelated individuals from San Felipe-Los Andes (n = 108), Santiago (n = 217), and Concepción (n = 225).
Article Synopsis
- Patagonia was one of the last places in the Americas settled by humans around 15,000-20,000 years ago, and there's still a lack of research on the genomic diversity in this region.
- This study analyzes genome data from four modern populations in Central Southern Chile and Patagonia, as well as four ancient individuals from about 1,000 years ago, revealing strong genetic connections between these groups and other Native Americans.
- The findings indicate that the Native Patagonian Kawéskar and Yámana populations have maintained genetic continuity over the last millennium and suggest a historical separation between maritime and terrestrial populations, which later diversified.
Objectives: The human population history from Patagonia and Tierra del Fuego has been of great interest in the context of the American peopling. Different sources of evidence have contributed to the characterization of the local populations, but some main questions about their history remain unsolved. Among the native populations, two marine hunter-gatherers groups inhabited the Patagonian channels below the 478S: Kawéskar and Yámana.
