From which exact country did the camel originate?

Answer 1

[[They originated in the African deserts and expanded to different countries all over the world!]]

That answer is technically wrong. Camelid species originated in North America. Some migrated south and evolved into vicunas and guanacos (and later domesticated llamas). Others migrated back across the Bering Strait and developed into Bactrian and Dromedary camels (which have been domesticated since at least 2500 BC - not many exist in the wild anymore). The original camels in North America died out.

Answer 2

The dromedary camel is native to Arabia and the Bactrian camel is native to the dry deserts of Western, central and eastern Asia.
