It's a mistake to say that evolution is all just one direction. There are mammals that "de-evolved" and went back to the ocean for example. They were able to take attributes they got from living on land for millions of years and use them back in the ocean successfully.
I can picture how a Bigfoot might succeed in the forests if it followed the eating behavior of bears (gorging and hibernation) or had some kind of hunting ability. I don't see what species it could have evolved from 15,000 years ago around here. We haven't found any fossils like Neanderthals or other human subspecies in North America.
I think evolution is more the result of mutations within a species, if those mutation give the effected species a better edge then that mutation gets past on until it isn't a mutation any more, it's an inherent trait. Then the process starts over again. Reminds me of the old adage, "It's only kinky the first time or two, after that it's just what you do."
True, we haven't found any fossils, but that doesn't mean the process started here. The Gigantopithecus existed in China for around 300K years, then died out apparently. Bigfoots might have evolved in Asia and migrated here in largely their current form. That would explain the lack of finding Neanderthals on North America, and if we conjecture a bit further then the reason we don't see any Bigfoots in the fossil record could be that they haven't been here long enough to be there. A species that potentially is only 15k years old in still in it's primordial infancy.
One day they could be the dominate species on the planet.
And yes, I am simply thinking out loud and typing it out to see what everyone else thinks about it as well. That is what this is all about after all, exchange of thoughts and ideas, even highly hypothetical ones.
