Oh for goodness sake. A article proclaiming a panel of 'experts' , while having quoted another article actually merely saying a 12 strong team of 'scientists' AND Yeti enthusiasts apparently pluck a random figure from the air based on...eeer?
I have a degree in Biology/Genetics. I bet if I had been there, they would have quoted me as an 'expert scientist' despite me not even being adequately qualified to set up lab experiments in a junior school.
Seriously, articles like this are the reason why science is regarded as an optional belief system by so many people. Internet rumours built on Chinese whispers built on faulty 'science' reporting, paid for by people trying to advertise something. Wow the world is so depressing sometimes.
Who knows, maybe there could be a branch or two of the ape family tree we haven't found yet, although it is very unlikely that there are many large mammal species left to be discovered now, let alone something like this.
However regardless of that, this article is meaningless.
'Irrefutable evidence' ---> If something is irrefutable it is proven in an unquestionable way. You can have irrefutable proof, not evidence. It's like saying we have a 'absolutely certain possibility'. Evidence is a means to an end. Morons.
