The impact of the diffusion of maize to the Southwestern United States
Date:12/8/2009

ut early maize in the Southwest with genetic, paleoecological, and historical linguistic studies.

Corn from five sites in Arizona and New Mexico now predates 2,000 B.C., which makes it too early to be explained by diffusion of settled Mexican villagers, said Fritz.

"No artifacts or features of any type point to in-migrating Mesoamerican farmers; in fact, continuity of local traditions is manifested, with independent invention of low-fired ceramics and with the construction of irrigation features in the Tucson Basin dating earlier than any known south of the border," she said. "We interpret the linguistic evidence as favoring a very early (beginning shortly after 7,000 B.C.), north-to-south movement of Proto-Uto-Aztecan hunter-gatherers and subsequent division into northern and southern Uto-Aztecan-speaking groups. "

These two groups do not share words and meanings for maize because, according to the researchers' scenario, farming post-dates their separation.

"We think the Southwest stands as a region in which indigenous foragers adopted crops and made the transition to agriculture locally rather than having been joined or displaced by in-migrating farming societies," Fritz said. "Peter Bellwood may well be correct that long-distance movements account for some examples of the expansion of languages and farming technologies, but cases like that of the Southwest are very important in demonstrating that this pattern did not apply universally."
