Study Reveals Extensive Genetic Diversity and Migration Patterns in Indigenous Americans
A comprehensive international study has unveiled the largest genomic dataset of Indigenous American populations, highlighting their complex evolutionary history and unique genetic diversity. Published in Nature, the research involved sequencing 128 high-coverage whole genomes from individuals across eight Latin American countries. This effort, part of the Indigenous American Genomic Diversity Project, aimed to address the historical underrepresentation of Indigenous populations in genomic research. The study discovered over a million previously unknown genetic variants and identified a third wave of migration into South America, occurring approximately 1,300 years ago. This migration involved Indigenous populations from Mesoamerica moving into South America and the Caribbean, leaving a genetic footprint still visible today. Additionally, the research confirmed ancestral connections with Australasian populations and archaic hominids like Neanderthals and Denisovans.
