What the article doesn't mention is the ongoing issue around the identity of the Kwhit skull that is in the possession of the Moscow investigators. This skull belonged to of one of the ancestors of Yana, the wild woman of Central Asia. It was disinterred by Igor Burtsev many years ago, and many people have pronounced on its non-human appearance.
Professor Bryan Sykes of Oxford University conducted a DNA matching study of many of the hair and bone samples of purported yeti and bigfoot origin that he had been provided with. Many of these he identified as coming from known animals.
When it came to the Kwhit skull, however he hesitated. Initially, he said that it might be the descendant of an African slave that had somehow ended up in the area. More lately, however, he has been quoted in the press as saying that the skull doesn't match that of any known human group, and that , though its origins were still most probably African - it may have been a part of a species that came from Africa many thousands of years ago.
It may yet turn out that that the Russian investigators hold the only real physical evidence there is of relict hominids.
