It has not been ascertained whether Filipa, his first wife, was deceased or had been abandoned by Columbus. › Columbus used this time of relative peace and quiet to study and devise his plans for the journey to Asia. › Europe had an established land route — the famous Silk Route — to mighty Asian empires such as China and India during the Mongol Empire. She won the 1903 Nobel prize in Physics and the 1911 Nobel prize in Chemistry. One of the pioneering explorers of the medieval world, Christopher Columbus has achieved a universal reputation for bravery, determination, self-belief and the will to venture out of predefined boundaries in search of hitherto… This voyage was sanctioned by the King of France to discover a western passage around North America, to the rich markets of Asia.

But dromedary origins were lost in the mists of the desert, though not any more! Camel train image ; Credit: Dr Abddul Raziq Kakar Faisal Almathen of the King Faisal University, KSA, and the University of Nottingham, Pamela A Burger of Viennas Institute of Wildlife Ecology and renowned colleagues from many continents have revealed a deep genetic insight into the origins of the actual ship of the Arabian (and Asian and African) desert, a transport system known as the dromedary. Camels (Camelus dromedarius) are a food, milk and racing interest to modern people, but in the past, they would have been wild neighbours in a corner of Arabia. Wild ass at present occupy a similar niche in the same piece of desert. Like wild horses in northern Asia and several other species, the camel has supplemented its gene pool by interbreeding with domesticated examples of their own species. The involving story here is that camel trains across the vast wastes have helped the species to retain a greater gene pool, because the individuals bred at both ends of each trade route. It is recorded in medieval times that thousands of dromedaries were used in, for example, the Asian Silk Road and the Arabian Incense Route 1083 living camels displayed very little variation, showing just how successful the gene flow has been. Ancient remains with mtDNA however have been successfully reconstituted and confirm a high original diversity too. This contrasts with the likelihood that the wild dromedary was already becoming extinct even before it was domesticated.
