Robert why do you say that the modern races are what the humans phenotype eventually ends at? I feel if we went back to neanderthal times someone would say ” this is where all possible phenotype point to”. Don’t you think it’s possible that another phenotype could arise or would that make it a new species at that point?
All of the recent races seem to be crashing down into a limited subset of possible of phenotypes.
Perhaps at any given time in evolution, only a limited subset of all possible phenotypes are available. That is why “Neandertal” is not one of the possible human phenotypes available today, though it was long ago.
