They said they were going to provide DNA evidence. Let's see.
I don't see how DNA evidence would help. We have no Bigfoot DNA to compare it against.
All pro-bigfoot-ites would claim Bigfoot is obviously so closely related to man that any human-looking DNA (and perhaps some chimp DNA for good measure) confirms it as Bigfoot.
Dyed in the wool anti-Bigfootians would simply claim the opposite and say any smidgen of remotely human-like DNA in there is conclusive proof its a hoax perpetrated by some guy grinding his toenail clippings into a fine powder and scattering it over a gorilla carcass he stole from the zoo.
