Neolithic farmers began to keep them for easy access to milk and meat, primarily, also for their dung, which was used as fuel and their bones, hair, and sinew for clothing, building, and tools. The earliest remnants of domesticated goats dating 10,000 years before present are found in Ganj Dareh in Iranian Kurdistan. Goat remains have been found at archaeological sites in Jericho, Choga, Mami, Djeitun and Cayonu; dating the domestication of goats in western Asia at between 8000 and 9000 years ago. Domestic goats were generally kept in herds that wandered on hills or other grazing areas, often tended by goatherds who were frequently children or adolescents, similar to the more widely known shepherd. These methods of herding are still used today.
