Cereals are annual herbaceous plants that belong mainly to the family of the Poaceae, whose seeds are rich in starch.
The domestication of these plants represents the transition, for humanity, from the life of nomadic hunter to that of a sedentary farmer. Furthermore, they are the basis of our diet.
Cereals grains are widely spread throughout the world, and the origins of man-grown types are to be found in different regions of the planet: the autumn-winter Cereals come from the Fertile Crescent and then spread in all temperate areas, until the Polar Circle. Rice and Buckwheat appeared originally in the east, on the slopes of the Himalayan chain; Sorghum, Millet and Teff are native to Africa; Maize, Quinoa and Amaranth are born spontaneously in the Andean regions of South America and Central America.
