Document Summary
Maize, manioc, sweet potato: phytolith evidence (know for exam) Changeover from teosinte to maize took millennia through selective processing. Occurred in forest areas of sw mexico and panama: guila naquits cave in oaxaca 4265 bc, san andres on gulf coast of mexico 5100 bc. Diffused from sw mexico and panama to the rest of the americas after 3000 bc. By 4500 bc maize, squash, and beans (foraging) Evident in staple isoptope analysis on skeletal remains, change in diet leaves its marks on skeletons, teeth and molars wear down with change: san marcos 3600 bc. Highlands 2500 bc: domesticated llama, alpaca, and guinea pig, potato and quinoa. Peruvian coasst: 3000 bc, farming supplements anchovy fishing and gathering, cotton production begins 2500 bc = skilled weavers, no archaeology evidence for most fishing communities because of underwater. El nino spurs agriculture, blamed as the cause because it forced fish and other sea life away from reach.
