Damn, you mean Bones doesn't really work for the the Smithsonian and isn't really married to Angel? My world is shattered. Next you are going to tell me Finding Bigfoot and Ghost hunters isn't real.

Of course I know it is not real but there is some truth in their science and it is not too hard to determine where the truth is.

You are right fossil if the test does not get a match it could indicate an unknown species, but will be reported as inconclusive. I do believe there are Sasquatches around, my wife saw one many years ago and I believe her description of her encounter. I believe there existence will never be proven because there will always be those who wouldn't even accept proof with a captured live specimen.
