Camels are well known for their ability to survive the hot and dry conditions of the desert, but a study suggests they once thrived in colder climes.
Scientists have unearthed the fossilised remains of a giant species of camel in Canada's High Arctic.
An analysis of protein found in the bones has revealed that this creature, which lived about 3.5 million years ago, is an ancestor of today's species.
The research is published in the journal Nature Communications.
Dr Mike Buckley, an author of the paper from the University of Manchester, said: "What's interesting about this story is the location: this is the northernmost evidence of camels."
