Agriculture

It is hard to believe that the Ice Age ended about 11,000 years ago. The Agricultural Revolution practically began when the Ice Age ended. 

It is interesting to learn about when and where agricultural breakthroughs happened. For example, in Southwest Asia, my agricultural breakthrough occurred between 9000-7000 b.c.e. In Eastern Woodlands of N.A. between 2000-1000 b.c.e. 

There is a section on ch.2 of the Strayer book the writes about corn. There is a timeline of the evolution of corn. It has history as early as 9000-8000 b.c.e. until 16th-18th century c.e. 

Agriculture dates back to as many thousands of years ago.
