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."
Cold
conditions
The mid-Pliocene
Epoch was a warm period of the Earth's history - but surviving in the Arctic would have still been tough.
The ancient
camels would have had to cope with long and harsh winters, with temperatures
plunging well below freezing. There would have been snow storms and months of
perpetual darkness.
