Some fun facts: Grover Krantz, the originator of the concept of human persistence hunting (which Wikipedia labels "conjecture"), was better-known as a staunch advocate for the existence of Bigfoot (there is of course no such thing as Bigfoot - it's obviously a Yeti in a gorilla suit). Interestingly, he didn't propose it as an explanation for bipedality, one of the unique characteristics of the human lineage, but rather as an explanation for our big brains, speculating that bigger brains would allow persistence hunters to survive a large fraction of their brain neurons dying from the heat stress that would result from long-distance running during the day.

For apparently no reason, Krantz' skeleton and that of his favorite dog are on display at the Smithsonian.
