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. [4] 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.
The earliest cultivated plant in North America is the bottle gourd, remains of which have been excavated at Little Salt Spring, Florida dating to 8000 BCE. [7] Squash (Cucurbita pepo var. ozarkana) is considered to be one of the first domesticated plants in the Eastern Woodlands, having been found in the region about 5000 BCE, though possibly not domesticated in the region until about 1000 BCE.
In 1988, the Israeli botanist Daniel Zohary and the German botanist Maria Hopf formulated their founder crops hypothesis. They proposed that eight plant species were domesticated by early Neolithic farming communities in Southwest Asia (Fertile Crescent) and went on to form the basis of agricultural economies across much of Eurasia, including Southwest Asia, South Asia, Europe, and North ...
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 ...
Centres of Plant Diversity (CPD) was established in 1998 as a joint classification initiative between the World Wildlife Fund (WWF) and the International Union for Conservation of Nature intended to identify the areas in the world that are of the highest conservation value in terms of protecting the highest number of plant species.

The geographical spread is therefore considerable, suggesting several independent domestication episodes for the same plant. It is therefore possible that the pre-domestic agriculture of the PPNA was located in the same places. This seems at least to be confirmed in several cases.
Domestication of plants is an artificial selection process conducted by humans to produce plants that have more desirable traits than wild plants, and which renders them dependent on artificial usually enhanced environments for their continued existence. The practice is estimated to date back 9,000–11,000 years.
Horticulture began with the domestication of plants 10,000–20,000 years ago and has since been deeply integrated into human history. [2] [3] The domestication of plants occurred independently within various civilizations across the globe.
