I am not so sure about this. There must be some reason
humans developed the ability to outrun almost any animal
over the long haul. Only a few dog species, and maybe
reindeer or a few migratory species, can out run a trained
long distance runner. Australian Aboriginals hunted this
way, I read somewhere. Some American Indians did too.
