Humans do have very good endurance, but that's not because of bipedalism,
it's because we are better at getting rid of unwanted heat than any other
land animal of our size, and that's because we have sweat glands on every
part of our skin, and that's because we don't need a permanent coat of hair,
and that's because we're smart enough to make an artificial coat and put it
on and take it off as needed.
