On the basis of links to southern Pan-American maize alone, this could be a result of a simple one-way dispersal of the Pan-American lineage where El Gigante maize acts as an outgroup to southern Pan-American genomes. However, this pattern does not explain the AIM-based links between El Gigante and earlier-dispersed South American lineages, nor the outgroup- f3 results tying El Gigante to ancient genomes in South America. Instead, we hypothesize that the South Ameri...
