South America might have been settled over 18,000 years ago, with evidence of a genetic bottleneck around 12,800 years ago, per Y chromosome genomic analysis
IMAGE: COLORED CIRCLES REPRESENT GEOGRAPHIC DISTRIBUTION AND SUB-LINEAGE MEMBERSHIP AS SHOWN IN THE INSET TREE. DIVERGENCE TIMES ESTIMATED IN THIS STUDY ARE REPRESENTED IN ITALICS, IN KYA, AND WITH A 95% CONFIDENCE INTERVAL BETWEEN PARENTHESES (FOR MORE DETAILS SEE METHODS). THE SIZE OF THE CIRCLES IS RELATED TO THE NUMBER OF SUBJECTS AND IS SPECIFIED WITH THE "N" IN THE BOX TO THE RIGHT. INDIVIDUALS WITH MEXICAN ANCESTRY FROM LOS ANGELES HAVE BEEN ARBITRARILY REPRESENTED IN CITY OF MEXICO. view more
