Totality of the evidence says Hominoid. WE have pretty much ALL the ape-like behaviors/capabilities. On the contrary, apes lack many key human behaviors/capabilities. Sasquatch overlap the ape behaviors/capabilities along with us, but share some of our human behavior/capabilities. (We could enumerate all of these attributes here, but for the sake of brevity, I won't) For me, that clinches the taxonomy.
And what of the adaptive pressures that have forced specialization/differentiation between BF and humans? I have long believed this was the deadly technology that humans developed and Sasquatch apparently (for the most part) did not. We have hunted them in deep history, successfully too, of that I'm sure.
On this point also I have always pondered this: Why would a species that is very capable of inflicting death from a distance, choose to not do that when threatened? The BF that launched a boulder into the water next to where I was standing could just have easily taken me out with that same rock, and nobody would have been the wiser. This story gets repeated hundreds of times, and my conclusion is that it just chooses not to. I hesitate to say this is a moral choice on their part, but it sure looks like that. Self-preservation imbedded by millennia of adaptive experience maybe? i.e., if we kill one of the small hairless ones the rest will come and slaughter us all?
