Jumping gene enabled key step in corn domestication
Corn split off from its closest relative teosinte, a wild Mexican grass, about 10,000 years ago thanks to the breeding efforts of early Mexican farmers. Today it's hard to tell that the two plants were ever close kin: Corn ...

Domestication
Domestication (from Latin domesticus) or taming refers to the process whereby a population of animals or plants, through a process of selection, becomes accustomed to human provision and control. A defining characteristic of domestication is artificial selection by humans. Some species such as the Asian Elephant, numerous members of which which have for many centuries been used as working animals, are not domesticated because they have not normally been bred under human control, even though they have been commonly tamed. Humans have brought these populations under their care for a wide range of reasons: to produce food or valuable commodities (such as wool, cotton, or silk), for help with various types of work (such as transportation or protection), for protection of themselves and livestock, to enjoy as companions or ornamental plant, and for scientific research, such as finding cures for certain diseases.
Plants domesticated primarily for aesthetic enjoyment in and around the home are usually called house plants or ornamentals, while those domesticated for large-scale food production are generally called crops. A distinction can be made between those domesticated plants that have been deliberately altered or selected for special desirable characteristics (see cultigen) and those domesticated plants that are essentially no different from their wild counterparts (assuming domestication does not necessarily imply physical modification). Likewise, animals domesticated for home companionship are usually called pets while those domesticated for food or work are called livestock or farm animals.
