Scott Carrier made a very interesting argument that humans are exceptional distance runners a decade or so ago on This American Life. It wasn't exactly a scientific analysis, but after interviewing some biologists and trying to chase down antelope (e.g. http://www.amazon.com/Running-After-Antelope-Scott-Carrier/dp/1582431116), he concluded that humans actually aren't all that good at it.
