It is not clear that we have. There were two exoduses from Africa. The Neanderthals may have been a different species.
The Dinosaurs continued for hundreds of millions of years. Humans since that second exodus from Africa have only lived some tens of thousands of years. A split of a species into two distinct species takes a long time.

A species? What is species? Do you mean like birds or parrots specifically.
http://en.wikipedia.org/wiki/Parrot
Parrots are birds of the roughly 350 species in the order Psittaciformes, found in most warm and tropical regions. Also known as psittacines (pronounced IPA: /ËsɪtÉsaɪnz/),[1][2] they are usually grouped into two families: the Psittacidae (true parrots) and the Cacatuidae (cockatoos). Characteristic features of parrots include a strong curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Most parrots are predominantly green, with other bright colors, and some species are multi-colored. Cockatoo species range from mostly white to mostly black, and have a mobile crest of feathers on the top of their heads. Most parrots are monomorphic or minimally sexually dimorphic.

I disagree that we have. I think that humans continually try to overpower those they view different or weaker, and try to change everything about them or just what is different.
We also congregate with those that are similar to us. Not only by countries, but when we go to another country to live, by living near those more like us within that environment. I don't think it is that we have remained as one species but more that we have each fought to remain.

It takes millions of years to develop a species, not the 100,000 or so years homo sapiens have been around. 15 or so hominids are extinct, but during their time millions of years ago, one could've wondered why they were the only "one" species. (that is if they had the cerebral cortex reasoning, which they didn't).
My question is "when will we get rid of our tail bones, appendix, man nipples, body hair and other useless appendage and remnants of our reptillian past?"

For one thing, it may not have been so long ago that the species first evolved. Secondly, the speciation requires isolated populations, no interbreeding. So far, somehow, humans have not been isolated.

We have not remained one species, specifically. We are Homo sapiens sapiens, a SUB species of Homo sapiens who no longer exists. Someday we may evolve into another sub-species.

Who knows? Maybe, we're more than one already. It could be so slight a difference, that we are unable to detect the difference with our limited technology.

Because you'd really have to be super drunk to screw an ape.
