Native Americans were farmers 3,000 years ago

WASHINGTON (AP) Ancient Americans were growing corn and building impressive villages in arid desert lands more than 3,000 years ago, far earlier than previously believed, according to new research.
Excavations of elaborate terracing built into a hillside in northern Mexico uncovered corn cobs and squash seeds that were dated at about 1500 B.C.
"We found that there was a high level of effort centering on this particular place," said J.R. Roney, a Bureau of Land Management archaeologist and co-author of the study. "That shows there was an agricultural lifestyle established then."
Roney and Robert Hard of the University of Texas, San Antonio, were to publish their findings Friday in the journal Science.
