Ready? I'm coming out on the ice with you...
The evolutionary theory is that there is a common ancestor and humans and apes are branches from that ancestor. Fossil evidence of that ancestor does not exist. Fossil evidence of the intermediary steps between that ancestor and humans does not exist. Fossil evidence of any intermediary step in determining the direction a speciation took (macroevolution) does not exist. That's why it's a theory.
Mutations have consistently been shown to decrease/diminish the information in the genetic code, not increase it. So, if you call mutations "evolving", then yes, we are evolving, but not into anything more complex than we already are. We're actually disintegrating which follows the theory of entropy.
Just like the fish. It can be argued that the fish which had eyes which mutated to be smaller, could only survive in the cave, so that's where they thrived and are found. That mutation decreased the genetic code... it did not enhance it.
Brrrrr.... it's cold in this water!
