Researchers analyzed DNA from 49 people who lived over a span of 10,000 years in Belize, Brazil, the Central Andes, and southern South America.
Notes on verification
Directly confirmed by the original peer-reviewed Cell study and corroborated by multiple independent press releases (HHMI, EurekAlert, ScienceDaily, UCSC, UNM) that consistently cite the 49-individual, ~9,000-11,000 year timeframe across the four regions.
