My research shows that the domestication of plants started around 9,000 years ago. Fig trees, variety of wheat and peas in the Near East were first 9,000 years ago. Barley and chickpeas around 8,500 years ago. These were followed by rice in asia 8,000 years ago along with potatoe, beans and squash in Central and South America also around 8,000 years ago.
