A study of one of the world's most important domesticated animals - the dromedary camel - has revealed how its genetic diversity has been shaped by ancient trade routes.
Scientists examined DNA samples from more than 1,000 one-humped camels.
Despite populations being hundreds of miles apart, they were genetically very similar.
Scientists explained that centuries of cross-continental trade had led to this "blurring" of genetics.
The findings are published in the Proceedings of the National Academy of Sciences.
One of the team, Prof Olivier Hanotte, from Nottingham University, explained that what made the dromedary so biologically fascinating was its close link to human history.
