Professor Sykes added: “There’s more work to be done on interpreting the results. I don’t think it means there are ancient polar bears wandering around the Himalayas. But we can speculate on what the possible explanation might be. It could mean there is a sub species of brown bear in the High Himalayas descended from the bear that was the ancestor of the polar bear. Or it could mean there has been more recent hybridisation between the brown bear and the descendant of the ancient polar bear.”
