"from before 5000 bce, people living in the tehuacán valley around what is now mexico city were collecting wild plants such as beans and amaranth, which they ate with chilli peppers. they lived out-of-doors except during the rainy season, when they lived in caves. they ground seeds for food, and they grew squash. between the years 5000 and 3500 bce, these people grew beans and an early variety of corn, which, with their squash, amounted to about ten percent of their food, the rest of their food having been acquired through hunting, fishing and gathering plants. in this span of 1500 years, their population increased ten times. after 3000 bce, they began to grow around thirty percent of what they ate, roughly half of this corn from a larger cob, and they began to raise turkeys. and by around 2500 they were growing much of what they ate, and they built villages next to their fields, with small pit houses similar to those of shang civilization. people in the tehuacán valley did not have goats, sheep or cattle to domesticate.   the bison, antelope and mountain sheep of north america had not migrated into mexico. people there had no animal to pull a plow.   farmers in central mexico continued to use the digging stick. they planted in the spring and harvested in the fall. their beans and corn did not provide enough protein for young children or lactating women.   needing game to supplement their diet, in the summer they hunted jackrabbits and in the winter they hunted the deer that descended from the hills." source:
