A theory that the mythical yeti is a rare polar bear-brown bear hybrid animal has been challenged. Last year, Oxford University genetics professor Bryan Sykes revealed the results of DNA tests on hairs said to be from the Abominable Snowman. The tests matched the samples with the DNA of an ancient polar bear. But two other scientists have said re-analysis of the same data shows the hairs belong to the Himalayan bear, a sub-species of the brown bear. The results of the new research by Ceiridwen Edwards and Ross Barnett have been published in the Royal Society journal, Proceedings of the Royal Society B. More details via BBC News.
