Strangely these animals that are so redolent of North Africa came from a different continent entirely. Want to guess? Well they actually came from North America.
They like a few other well travelled animals eg. horses and dogs all started off 20 million years ago on the continent of America. They weren't so much like the animals we know today. They were probably more like gazelles.
About four million years ago they crossed the Bering land bridge to Asia. They came extinct in North America during the last ice age and never migrated back.
It is unclear why they died out in North America. It could have been due to the change in vegetation which didn't favour the grazers. The fact that the weakened species lost its link to Asia as the Bering Sea took over between the two continents, 10,000 years ago. The remaining camels may just have been finished off by human hunters.
