Oryza sativa is comprised of two subspecies, indica and japonica, both of which are domesticated from a wild ancestor similar to O. rufipogon.
It should be noted that the variability is further enhanced by the existence of goldfish (C. a. auratus), which are domesticated ornamental fish that have been produced under artificial selection and are widespread throughout the world.
Issues regarding the weediness and invasiveness of the transgenic plant, as well as of gene flow into wild populations, will be of paramount concern in risk assessments of forest and range plants which are domesticated and otherwise modified for use as biofeedstock crops.
The behavioral traits of domestic pigs, which were domesticated around 9,000 years ago (Hemmer 1990), closely resemble those of its ancestor, the wild boar (Sus scrofa).
This has happened on limited scales with the oryx (which was domesticated by the ancient Egyptians), the springbok (which has been run with cattle for decades in Southern Africa), and the African buffalo and eland.
Peruvian cuisine is characterized by an array of cultural influences — not only Amerindian and Spanish but also Japanese, Chinese, and Italian — and an overwhelming fondness for the potato, which was domesticated in Peru around eight thousand years ago and of which the country cultivates more than three thousand varieties.
Cattle populations across northern Africa, in contrast, contained genetic influence from taurine cattle, which were domesticated at least 8000 years ago in the Fertile Crescent of Turkey and other countries.
While cats, which were domesticated 10,000 years ago, are excellent natural hunters, they are also savvy enough to hang around where they will get fed.
The European polecat is the sole ancestor of the ferret, which was domesticated more than 2000 years ago for the purpose of hunting vermin.
Coca leaf, which was domesticated over 4,000 years ago, is usually chewed with a bitter wood-ash paste to bring out the stimulant properties which are mild and similar to caffeine or nicotine.
This error then was compounded by confusion of the African bird (known variously, depending on sex, as the turkey-cock or turkey-hen) with the New World turkey, which was domesticated in Mexico prior to the Spanish invasion in 1518, and which is ancestral to the one we eat.
