The pendular running gait described in this article as one of the most efficient bipedal gaits looks remarkably like the way eyewitnesses claim Bigfoot creatures move. In a Bigfoot hoax, one might use a gait that is unhuman but energy efficient, as the costume would be rather heavy. On the other hand, since such a gait is energy efficient, perhaps an unknown species of massive primates might have evolved to use it.
