I just came across what looks like an older video called
An Introduction to Bigfoot : A Forfend Historical Documentary
Where they make the claim that sasquatch arose from monkeys that seemingly crossed the Atlantic from Africa to South America on vegetative rafts, then diverged into to "the sasquatches" 3 species of large stature while still in South America, only later migrating northward due to interspecies conflict. The clip goes on to ascribe certain communicative behaviors to sasquatch of differing intelligences, the heights of which being woodknocking.
Ive never seen this one before, nor heard the Africa~~>South America ~~>North America route..
Here s the link
The description of the development and proffered taxonomy almost make me think this was done by those trolling the community, but they sound sincere(well ...they re not giggling, anyways) not much in the way of stills, but rather what seems like a lot of stock nature footage.....
