The FBI tested Bigfoot hair back in the 1970s

Declassified documents have revealed that the FBI once tested hair and tissue samples of an alleged Bigfoot.
93-year-old Peter Byrne, who has spent decades hoping to prove the existence of the creature, repeatedly wrote to the FBI back in 1976 to have tests conducted on samples he'd collected.

"We do not often come across hair which we are unable to identify and the hair that we have now, about 15 hairs attached to a tiny piece of skin, is the first that we have obtained in six years which we feel may be of importance," he wrote to FBI Assistant Director Jay Cochran Jr.

Byrne also wrote to ask about tests conducted on other samples that the FBI had obtained.

"Will you kindly set the record straight, once and for all, inform us if the FBI has examined hair which might be that of a Bigfoot, when this took place, and if it did take place what the results of the analysis were," he wrote. "Please understand that our research here is serious."
The FBI replied a few weeks later to state that while the bureau normally only conducts such analyses as part of criminal investigations, "occasionally, on a case-by-case basis, in the interest of research and scientific inquiry, we make exceptions to the general policy."

"We will examine the hairs and tissue mentioned in your letter."

A follow-up letter later detailed the results which "included a study of morphological characteristics such as root structure, medullary structure and cuticle thickness in addition to scale casts."

"Also, the hairs were compared directly with hairs of known origin under a comparison microscope."

"It was concluded as a result of these examinations that the hairs are of a deer family origin."

sure, its not so much "falling for it" as a deep belief, sometimes too we are dealing with people who do not have such a defined line between real and imaginary, or mystical if you will. without spoiling the ending piney is one of the few here who has put time in hunting bf and based his opinions on that, so its pretty cool.

It's all in the technique of using shadows and being a good mimic but being born with pointed ears, fangs and eyes that turn yellow helps a lot.  The power of suggestion is a great tool too. False memories are fun. Reputation creates it's own ideas and memory of events.

I wouldn't call myself a Bigfoot "believer" per say, that would indicate a level of certainty I don't have.  However, I do suspect that an extant descendant of Gigantopithecus does exist today, accounting for the various sightings of Bigfoot/Yeti/Skunk Ape/etc.  Considering that the mountain gorilla was not discovered until 1902, I don't think that this theory is wildly speculative.  Certainly we don't have the sort of evidence for Bigfoot like we do for the Chupacabra (multiple videos, stills, corpses, and DNA test with skin biopsies ruling out mange).  In fact, in the latter case, it's...

I suspect in the case of the chupacabra you are talking about a type 2 chupacabra. I was not aware of any cases of type 2 bodies where mange had been ruled out. I woould be interested in learning about those cases.

chupra type 1 was never anything but myth, hoax and imaginations, chupra type 2 is a blanket term something of an amalgamate for a hairless canid type creature who may be suffereing from mange ( no, never ruled out, cant be ) it may be a hybrid or mutant, most people who get a body just crave attention and $$$ not furthering science the one popped up stuffed on ebay for like 10k but tests just seem to be vauge i believe on purpose, one expert will say one thing another something else, with the type 2 trend it got so convoluted and down right cheesy i moved on.

Some people also have a type 3 chupacabra category which is all animals that the person cannot identify. On a recent trip I saw a pine marten which for many people would have been assigned chupacabra. I also saw a small rodent, possibly a lemming. It could have been incorrectly assigned to mouse or dwarf chupacabra, LOL. Chupacabra is pretty much the same as "I don't know."

this is sadly true, its that chessy asinine mindset of "i dont know so it must be xxxx" i think thats my biggest hang up with dear true believers, no matter how hard i try when they play the "i dont know, so it must be xxxx" card it kills any and all interigrity and credibilty they might have had with me, simple no way to reach a definitive answer from "i dont know".

Yeah, the simple IDK is the more honest answer.
