Well, that does depend on a definition of superiority. Since humans seem to be the only entities proffering an opinion, I believe we win.
Since I don't advocate the perfect creation
of man in situ without the benefit of
evolution, I'll leave the quibbling of just
what superior means to the creationists
who proclaim it. The point of the
exercise, at any rate, is that humanity
has evolved from something different
than what we see walking around
today.
