Well, if the case is parallel evolution, the species would show the same general tendency (increase in brain size and standing straight), but even when we are the same species the difference between us would be reflected in the race right? Still, a coupling between different races would still result in fertile children.
Thats why I thought that maybe parallel evolution was more likely but I am no antrop. nor biologist...
