'step' and 'evolution' should rarely be used in the same sentence. The reason we perceive human evolution as a series of steps is because all we have to go on are a relatively small number of archaeolgical findings. As we keep filling in missing links, the disction between all the different names like hom sapien homo erectus etc will blur.
Evolution occurs every single generation. Evolution, in the 1st world at least, is not so much about survival any more, its about the naughtier side of evolution, who does it the most without a condom.
Additionally, if there is a 'next step' it will have 3 heads and only one arm
