why DID we evolve into humans?

this is the simplaiest way to Put it with all of Evolution. it happened so the creature could survive. there is no Real reason Humans are Humans its just as Simple as that . We didn't set out to Become humans it just happened ok
C=cause E=effect
(C)we needed a way to Avoid being Hunted By more dangerous animals.(E) so we Started living in social groups(happened before primates)(C) we Need to Eat better food out of Danger
(E) we evolved the ability to use tools (chimps do this)though it happend there is no Goal Evolution doesn't work like that.
we just Happened it as simple as that Chance is all it was. we need to survive so we Evolved thats all.[This message has been edited by DC85, 07-04-2003]

well I have no doubt Evolution takes place however I can't see it ALL as Random Mutations......... Animals need to adapt so they evolve to the change in the enveronment. I can't Believe that the Human Brain just was all Random mutations
However I will agree Random Mutations take place for Example a Place that never or barely changes animal species still Evolve. Dinosaurs are the best Example of this. I don't think it can be all random........
