Great find Nygdan,
I am of the opinion that evolution happens a lot faster thain previously theorised. I think that 4 million years could be ample time for a species to evolve from one state to something radicly different

We as humans are fundementaly the same species but due to inherant environmental factors we have evolved into the races you see today.
