Farmed deer: new domestic animals defined by controlled breeding.

The domestication of plants and animals is recognized as pivotal in mankind's social evolution. Yet, surprisingly few species have actually been farmed, prompting speculation as to which attributes are needed for successful domestication. Although red deer were the staple source of meat throughout Europe in the mesolithic, they have not been widely domesticated, leading many ethologists to argue that they are behaviourally unsuitable. Recently, the most widely accepted criterion of domestication, the ability of farmers to control the breeding of a species, has been fulfilled in red and other species of deer with the widespread adoption of even the most technologically advanced methods of artificial breeding. Simultaneously and conversely, the population growth of wild deer in many temperate parts of the world has stimulated a search for contraceptive techniques.
