Bigfoot is an Ape – These folks follow from the earliest investigators, notably John Green and Grover Krantz. They hold that bigfoot is a real creature somehow related to modern apes. They have almost universally held to scientific materialism in their writing. The difference between them and Extreme Skeptics is their exposure to and openness to evidence. Note that this viewpoint doesn’t spring from physical evidence. This is the crowd that supports the idea of bigfoot descending from Gigantopithecus, without any real physical evidence to support this theory (beyond the size of bigfoot).
I think Lisa Shiel and some others would agree.
BlogSquatcher has parsed the “paranormal bigfoot” theories into distinctive categories. Instead of the sort of catch all “paranormal bigfoot” he’s divided these ideas into Paranormal, Inter-dimensional, UFOs, etc.
It’s clear from this post and others the BlogSquatcher knows his or her stuff.
