where did the ancestors of all camels first live
Camel The direct ancestor of all modern camels, Procamelus, existed in the upper Miocene and lower Pliocene.[64] Around 3â€“5 million years ago, the North American Camelidae spread to South America as part of the Great American Interchange via the newly formed Isthmus of Panama, where they gave rise to guanacos and related animals, and to Asia via the Bering land bridge.[15][59][60] Surprising finds of fossil Paracamelus on Ellesmere Island beginning in 2006 in the high Canadian Arctic indicate the dromedary is descended from a larger, boreal browser whose hump may have evolved as an adaptation in a cold climate.[65][66] This creature is estimated to have stood around nine feet tall.[67]
