Zusammenfassung:	Domestic pigeons were derived from Rock Doves (Columba livia) by artificial selection perhaps 5,000 ybp. Feral pigeon populations developed after domestics escaped captivity; this began in Europe soon after initial domestications occurred and has continued intermittently in other regions. Ferals developed from domestic stocks in North America no earlier than 400 ybp and are genealogically closer to domestics than to European ferals or wild Rock Doves. Nevertheless, North American ferals are significantly closer in skeletal size and shape to European ferals and Rock Doves than to domestics. Natural selection evidently has been reconstituing reasonable facsimiles of wild size and shape phenotypes in feral pigeons of Europe and North America.
