Agriculture began because of population density, along with climate change. In the book The Great Human Diasporas, Luigi Luca Cavalli-Sforza claims that dense populations “exceeded the limit for survival,” which led them to abandon hunting and gathering for agriculture (140). The changing global environment further fueled this change. The rise of agriculture originated in three different regions, including the Middle East, China, and South America. The domestication of cereals first evolved in the Middle East, and later spread to different areas throughout Europe, as well as northern Africa. Agriculture spread throughout China as well, and Cavalli-Sforza claims that “millet-farming villages” from the Neolithic period have been discovered in the area (142). In Mexico, about 8,000 years ago, many kinds of crops were being cultivated, including
