How is it that a single human ancestor 2 million years ago gradually populate the Earth and yet not evolve into a dozen different species?

How do you know that a dozen different species will not evolve. Who knows what will happen over the next five million years?

First of all, I'm a Creationist, not an Darwinist. My point is it doesn't make sense that a human ancestor dispersed around the world would not evolve into separate species over time. What animal do you think hasn't done that?
