In
Europe, northern
Africa, and western
Asia, the original domesticated geese are derived from the
greylag goose, while in eastern Asia, the original domesticated geese are derived from the
swan goose; these are commonly known as
Chinese geese. Both have been widely introduced in more recent times, and modern flocks in both areas (and elsewhere, such as
Australia and
North America) may consist of either species or
hybrids between them. Domestic swan geese may be readily distinguished from domestic greylag geese by the large knob at the base of the bill, though hybrids may exhibit every degree of variation between the two species.
Charles Darwin remarked in
The Variation of Animals and Plants Under Domestication that the
domestication of geese is of a very ancient date. The earliest evidence of goose domestication dates back 7,000 years ago to the
Hemudu culture of the
Lower Yangtze River in
China. There is archaeological evidence for domesticated geese in
Egypt more than 4,000 years ago. It has been proposed that geese were domesticated around 3000 BCE in
southeastern Europe, possibly in
Greece, but reliable evidence of domestic geese comes from a much later period (8th century BCE) in the
Odyssey. Another potential domestication site is in
Egypt during the
Old Kingdom (2686–1991 BCE) due to iconographic evidence of goose exploitation, but this scenario for the original domestication event has been considered less likely. Geese were also herded by ancient
Mesopotamians for food and sacrifices and depicted in Mesopotamian art from the
early Dynastic Period (2900–2350 BCE) onwards. Certainly, fully domesticated geese were present during the
New Kingdom times in Egypt (1552–1151 BCE) and contemporaneously in
Europe, and goose husbandry involving several varieties was well established by the
Romans by the 1st century BCE. In the
Medieval Period, goose husbandry was at its peak with large flocks kept by peasants. Archaeological evidence of the domestic goose in northern Europe indicates that it was probably introduced into
Scandinavia during the Early
Iron Age (400 BCE–550 CE). ==Characteristics==
