Here's some information on gardening in ancient
times.(from an article in the weekly publication Science
News.)
A new study has pushed the beginnings of the
cultivation of maize in southern Mexico to 6,300 years ago. This is 800 years
earlier than previous estimates. This evidence comes from radiocarbon analysis
of cobs found in a 1966 dig.
Evidence of squash cultivation in North America has
been dated back to 10,000 years ago.
Beans were probably first domesticated around 4,000
years ago in southwestern Mexico.
These are Mexico's three major crops and most of
the evidence used for dating has come from five caves excavated 40 to 50 years
ago.
