lets revisit your previous post
In light of genetic isolation why would there be a repeat of accumulated mutations that occurred in a separate line to emerge yet again, especially when the occurrence of mutations part is random? There would be new mutations to select from, and new selective pressures working on them, all of this adds up to an emergence of something that would NOT be human since they would have taken an entirely different path due to the isolation of their genes and the circumstances.
New races of humans evolving out of primates is not what the theory of evolution would predict would happen. If that were to happen it would contradict the fundamentals of the process as we know it - what you are describing is not in any way congruent with the theory of evolution.
