A Vavilov Center (of Diversity) is a region of the world first indicated by Nikolai Vavilov to be an original center for the domestication of plants. [3] For crop plants, Nikolai Vavilov identified differing numbers of centers: three in 1924, five in 1926, six in 1929, seven in 1931, eight in 1935 and reduced to seven again in 1940. [4] [5]
Some foods have always been common in every continent, such as many seafood and plants. Examples of these are honey, ants, mussels, crabs and coconuts. Nikolai Vavilov initially identified the centers of origin for eight crop plants, subdividing them further into twelve groups in 1935.
This map shows the sites of domestication for a number of crop plants. Places, where crops were initially domesticated, are called centers of origin. This is a list of plants that have been domesticated by humans. The list includes individual plant species identified by their common names as well as larger formal and informal botanical ...
English: Map of the world showing approximate centres of origin of agriculture and its spread in prehistory: eastern USA (4000-3000 years ago), Central Mexico (5000-4000 ya), Northern South America (5000-4000 ya), sub-Saharan Africa (5000-4000 BP, exact location unknown), the Fertile Crescent (11000 ya), the Yangtze and Yellow River basins (9000 ya) and the New Guinea Highlands (9000-6000 ya).
Almost all the domesticated plants used today for food and agriculture were domesticated in the centers of origin. In these centers there is still a great diversity of closely related wild plants, so-called crop wild relatives , that can also be used for improving modern cultivars by plant breeding.
At least 11 separate regions of the Old and New World were involved as independent centers of origin. [35] Some of the earliest known domestications were of animals. Domestic pigs had multiple centres of origin in Eurasia, including Europe, East Asia and Southwest Asia, [36] where wild boar were first domesticated about 10,500 years ago. [37]
Map showing centers of origin of Saccharum officinarum in New Guinea, S. sinensis in southern China and Taiwan, and S. barberi in India; dotted arrows represent Austronesian introductions [7] There are two centers of domestication for sugarcane: one for Saccharum officinarum by Papuans in New Guinea and another for Saccharum sinense by ...
