As Professor of Human Genetics at Wolfson College, University of Oxford, Bryan Sykes is one of Britain's leading researchers in the field.
I've personally had my DNA tested by him!
It was during his research into the Blood of the Isles, wherein he determined the genetic make-up of modern Britons.
Had we intermingled into a mongrel race made up of Celts, Anglo-Saxons, Vikings, Romans, Normans and every other invader and immigrant? Apparently not! We still have our enclaves and very little of the twain will meet.
(Incidentally, my results showed a 98% chance that I'm a Brythonic Celt. In short, my DNA is Welsh. No real shock there then!)
But on this occasion, he was receiving samples purported to come from a Yeti. The hair from the cedar tree wasn't all that he was given. After sifting through all of the wild pig and goat hairs, the most promising offering had been skin. It turned out to belong to a bear. Then he tested the hair.
"Because we were half expecting a bear - because of the analysis of the skin sample - we went directly and asked the reaction to look for bear DNA." Prof Sykes explained on camera. "But there wasn't any there."
He and his team performed more tests. They looked specifically for humans, bears and primates, but none were a match. In fact, so far, it can't be identified as 'any known species'.
"It's certainly mysterious." Prof Sykes concluded. He also appeared dumb-founded, as if this was not the anticipated result. It must have made an impact upon him too.
In May 2012, Prof Sykes put out a call for any alleged Bigfoot, Sasquatch or Yeti hair. It was part of an announcement that he was teaming up with Michel Sartori, the director of Lausanne Museum of Zoology, in Switzerland.
The academics will test all of the hair samples, in order to establish for once and for all what grew them.
