Camels are amazing animals. Because of their unique adaptation to different and extreme environments, no other domestic animal (e.g. cattle, sheep or goats) can serve people as much as the domestic camel. Dromedaries and Bactrian camels, the two native camels of the Old World, were invaluable for the transportation of goods along the Silk Road.
Due to centuries of domestication, hybridization is very common, but difficult to see with an “untrained” eye. FIWI researchers have collected samples from over 120 dromedaries worldwide. Through genetic analyses, they were able to identify effective migration patterns that fit well-known trade routes on the Mediterranean coast, connecting northwest Africa with the north of the Arabian Peninsula. This is in line with the routes of the well-known caravans that traveled along the Silk Road to South Asia.
More about that in the nature ecology & evolution article BEHIND THE PAPER: Camel - the animal of the past, present and future by Sara Lado, Pamela Burger, and Elena Ciani.
