Professor Sykes’ research (part of a worldwide analysis of alleged Bigfoot samples), has yielded a remarkable result: that Zana’s ancestry was 100% Sub-Saharan African and that she was most probably a slave brought to the region by the ruling Ottomans.
To answer the riddle and establish what species she belonged to, Professor Sykes has tested samples from six of Zana’s living descendants. He has also recovered DNA from a tooth taken from the skull of one of her sons, Khwit. Such work is highly specialized and Sykes was the first geneticist ever to extract DNA from ancient bone.
But the big surprise in Sykes’ results was that Zana’s DNA is not Caucasian at all, but African. Khwit’s tooth sample confirms her maternal African ancestry and the saliva tests on the six living descendants show that they all contain African DNA in the right proportions for Zana to have been genetically 100% sub-Saharan African.
But that theory would not explain her extraordinary features, described by reliable eyewitnesses. There is an even more intriguing alternative theory. Having carefully studied the skull of Zana's son, Khwit, Professor Sykes believes there are some unusual morphological skull features – such as very wide eye sockets, an elevated brow ridge and what appears to be an additional bone at the back of the skull – that could suggest ancient, as opposed to modern, human origins.
And Sykes has raised the bold theoretical possibility that Zana could be a remnant of an earlier human migration out of Africa, perhaps tens of thousands, of years ago. If correct, Zana could be evidence of a hitherto unknown human 'tribe', dating from a distant time when the human species was still evolving and whose ancestors were forced into remote regions, like the Caucasus mountains, by later waves of modern humans coming out of Africa.
One of the Russian Almasty hunters, Dr Igor Burtsev, offers testimony in the Channel 4 documentary that may back this theory up. He unearthed Khwit's skull in 1971 and a few years later, showed it to a group of anthropologists in Moscow. They were, he says 'amazed', and identified a mix of 'primitive' and 'progressive' (modern) features in the skull. Lacking the scientific tools at Sykes' disposal, they could take it no further. Now Sykes is able to propose the theory with some confidence.
It is only a theory at this stage - and a bold and speculative one at that. But Professor Sykes intends to study it much further before reaching his final conclusions.
Zana’s story will feature in Bigfoot Files on Channel 4 on Sunday, November 3rd at 8.00pm. In the programme Mark Evans also meets former heavyweight boxing champion of the world, seven foot tall Nikolai Valuev, who admits to having a bit of a Neanderthal look himself. He is now Duma Deputy (the equivalent of an MP) for Kemerovo in Siberia and fascinated in Almasty. The programme also investigates some of the other claimed sightings of the creatures in Russia.
The series, made by Icon Films, examines the stories behind famous Bigfoot sightings and Mark Evans meets people who believe passionately that other species of hominid exist. A book by Professor Sykes about his research The Yeti Enigma: A DNA Detective Story will be published by Coronet in Spring 2014.\
The programme is available to view and there are images available.
