2013年7月18日 · In order to investigate the underlying genetic structure and genomic ancestry proportions of Peruvian subpopulations, we analyzed 551 human samples of 25 localities from the Andean, Amazonian,...

2025年1月23日 · Andean peoples, aboriginal inhabitants of the area of the Central Andes in South America. Although the Andes Mountains extend from Venezuela to the southern tip of the continent, it is conventional to call “Andean” only the people who were once part of Tawantinsuyu, the Inca Empire in the Central

Mesoamerican and Andean ethnicity indicates genetic origins in “Mesoamerica” which is a historical term denoting the geographical region which housed pre-Columbian Mesoamerican civilizations — such as the Aztec Empire — roughly corresponding to modern Central America.

2020年5月8日 · The team discovered genetic exchanges both within the Andes and between Andean and non-Andean populations. Ancient people moved between south Peru and the Argentine plains and between the north Peru coast and the Amazon, largely bypassing the highlands, the researchers found.

These analyses revealed highly specific Native American genetic ancestries and great intragroup homogeneity, along with limited traces of gene flow mainly from the Andes into Peruvian Amazonians.

2021年12月5日 · Argentinian individuals show a broader range of indigenous ancestry: some cluster closer to the Southern/Amazonian Native Americans, while others cluster with the Latino Peruvians and the Andean group, reflecting a rich diversity of pre-Columbian roots in Argentina, whose geography spans the breadth of the continent from the Andes to the ...

2023年7月10日 · We generate genome-wide data from 64 participants from three Mapuche populations in Southern Chile: Pehuenche, Lafkenche, and Huilliche. Broadly, we describe three main ancestry blocks with a common origin, which characterize the Southern Cone, the Central Andes, and Amazonia.

2020年12月4日 · Genetic data from 18 Peruvian populations reveal the following: 1) The between-population homogenization of the central southern Andes and its differentiation with respect to Amazonian populations of similar latitudes do not extend northward.

Here, we present a time series of ancient whole genomes from the Andes of Peru, dating back to 7000 calendar years before the present (BP), and compare them to 42 new genome-wide genetic variation datasets from both highland and lowland populations.

2020年5月7日 · The analyses revealed that by 9,000 years ago, groups living in the Andean highlands became genetically distinct from those that eventually came to live along the Pacific coast. The effects of this early differentiation are still seen today.
