fterward I found to search the original from www.wikipedia.org, It described, Chilli have been a part of the human diet in the Americas since at least 7500 BCE. The most recent research shows that chilli peppers were domesticated more than 6000 years ago in Mexico, in the region that extends across southern Puebla and northern Oaxaca to southeastern Veracruz, and were one of the first self-pollinating crops cultivated in Mexico, Central and parts of South America.
