The domestication of plants is one of the first steps in moving towards a full-fledged agricultural economy, although the process is by no means a one-directional movement. A plant is said to be domesticated when its native characteristics are altered such that it cannot grow and reproduce without human intervention. Domestication is thought to be the result of the development of a symbiotic relationship between the plants and humans, called co-evolution, because plants and human behaviors evolve to suit one another. In the simplest form of co-evolution, a human harvests a given plant selectively, based on the preferred characteristics, such as the largest fruits, and uses the seeds from the largest fruits to plant the next year.
The following table is compiled from a variety of sources, and detailed descriptions of the domesticates will be added to as I get to them. Thanks again to Ron Hicks at Ball State University for his suggestions and information.
