social conditions allowed. Hunter-gatherer societies persisted, even when increasingly confined to marginal areas. And within agricultural systems, hunting served to kill animals that prey upon domestic and wild animals or to attempt to extirpate animals seen by humans as competition for resources such as water or forage. When hunting moved from a subsistence activity to a selective one, two trends emerged: the development of the role of the specialist hunter, with special training and equipment the option of hunting as a "sport" for members of an upper social class The meaning of the word game in Middle English evolved to include an animal which is hunted. As the domestication of animals for meat grew, subsistence hunting remained among the lowest classes; however, the stylised pursuit of game in European societies became a luxury. Dangerous hunting, such as for lions or wild boars, often done on horseback or from a chariot, had a function similar to tournaments and manly sports. Hunting ranked as an honourable, somewhat competitive pastime to help the aristocracy practice skills of war in times of peace. In most parts of medieval Europe, the upper class obtained the sole rights to hunt in certain areas of a feudal territory. Game in these areas was used as a source of food and furs, often provided via professional huntsmen, but it was also expected to provide a form of recreation for the aristocracy. The importance of this proprietary view of game can be seen in the Robin Hood legends, in which one of the primary charges against the outlaws is that they "hunt the King's deer". In contrast, settlers in Anglophone colonies gloried democratically in hunting for all. In medieval Europe, hunting was considered by Johannes Scotus Eriugena to be part of the set of seven mechanical arts. Use of dog Although various other animals have been used to aid the hunter, such as ferrets, the dog has assumed many very important uses to the hunter. The domestication of the dog has led to a symbiotic relationship in which the dog's independence from humans is deferred. Though dogs can survive independently of humans, and in many cases do ferrally, when raised or adopted by humans the species tends to defer to its control in exchange for habitation, food and support. Dogs today are used to find, chase, retrieve, and sometimes kill game. Dogs allow humans to pursue and kill prey
