. The animals and man; an elementary textbook of zoology and human physiology. Zoology; Physiology. DOMESTICATED ANIMALS 271 The domestic ducks are derived from the wild duck Anas boschas, and have evidently originated from this ancestor independently both in China and in Europe. ' The domestic geese seem to have an older origin than the ducks; in fact geese are probably the oldest of domesticated birds. The ancestor of our races is the wild species Anas cinereus. The Chinese races how- ever, are descended from Anas cygmoi- des, and the early Egyptians seem to have tamed and used the Nile goose, Chenalopex egyptiaca. The domesticated peacocks are de- scended from the wild species of In- dia, Pavo cristatus. The turkeys trace their ancestry to the wild Meleagris gallopavo of North America. The swans are really only tamed wild kinds. Common spe- cies are the white swan of Europe, Cygnus olor, the black swan of New Holland, Cygnus atratus, and the black- necked swan of South America, Cygnus nigricoUis. The pheasants also are so far practically only partially tamed wild species, whose eggs however, are usually hatched under turkeys. Most of the kinds kept are from the Orient. Canary birds are descended from the wild species, Frin- gilla canariensis of the Canary Islands. But there has been some crossing of them with other species of wild birds,.
