| Research Abstract |
Teotihuacan was a mega-state in ancient Mesoamerica, but there are many uncertainties about its community and history owing to undeciphered writing system. To investigate its society through the genetic origins of individuals offered as sacrifices, we analyzed mitochondrial DNA of sacrifices of the Moon Pyramid at Teotihuacan. The Moon Pyramid sacrifices comprise some individuals with rare haplogroups: haplogroup A with a 9-bp deletion and haplogroup X. Based on the distribution of these rare haplogroups within the vicinity of Teotihuacan, we discuss this mega-state sphere of influence, possibly indicating it expanded from southwestern North America to the entire area of Mesoamerica.
