First of all, evolution is not a sequential process, there are no clear steps. Changes happen over time. All living organisms on Earth are undergoing evolution right now.
I think what you are looking for is human transitional fossils. Here are some for you:
Sahelanthropus tchadensis Homo rudolfensis Homo habilis Homo heidelbergensis Homo neanderthalensis
Cheers for the link, To be clear, I am not a creationist. I believe in evolution.
I guess I've missed a few fossil findings since school. I had in mind the following Australopithecus->Homo habilis->Homo erectus->Homo neanderthalensis-> homo sapiens
