	One advantage that humans have, which is primarily due to their
bipedalism, is the ability to walk and run at a wide variety of gaits.
A hunting human can eventually catch up with just about any animal,
(assuming that it doesn't hide or burrow) just by walking at a pace
that the prey cannot use efficiently.  Of course, this doesn't help
if you are being chased by a cheetah, but if you are chasing an impala,
you can eventually tire it out and catch up with it
