As near as I can tell, the field of human anthropology exists in a constant state of revolution anyway. I don't believe it needs a Sasquatch confirmation to become a more dynamic field, at all. Which is a good thing. Maybe, just maybe, those that practice in the discipline are starting to realize the so-called standard model for the linear ascent of ape to man was only as good as the next fossil hominoid species that was excavated... which now seems to be happening on a regular basis. There is no "done" in this field, or at least my prediction is we are a very long way from having the all the answers, and might never.
One of my standard gripes about scientists is they know better than to scoff at the idea of BF, and of those scientists, human anthropologists should know best of all.
Now, the biologists? Oh yeah. They will probably get the biggest jolt of all, and I'd line them right up behind the anthropologists as ones who should be the least surprised, but will probably be more so than experience would predict.
