> Why do people think that chimpanzees are our relatives?
Similar structures. We're a lot alike. Read up on taxonomy.
> form of animal
Because we *are* a form of Eumetazoa animal. Read up on Eumetazoa.
> isn't that putting man down
No. Maybe it's uplifting of other Eumetazoa animals. Read up on body plan genes.
> Don't you think we're more then that?
Of course. Read up on "Upper Paleolithic cultural revolution."
> Why exactly did man make the choice to leave the jungle and walk upright?
Our ancestors lived in a crummy place that was undergoing repeated droughts. It was marginal habitat for big dumb apes. Walking upright gave the ability to see farther over the plains, which is where things like the ancestors of lions and leopards lived. It also gave the ability for our ancestors to find food and carry it back to their sisters and their cousins and their aunts.
> Why didn't chimpanzees make that choice?
Those were big dumb apes that lived in a nice jungle, and not in a crummy place that had repeated droughts.
But don't worry, we showed them eventually. Who's an endangered species now, huh?
