There is no "primitive on the evolutionary scale" or 'advanced on the evolutionary scale'. There is no progress in evolution, only adaptation.
I agree that one reason that people don't get into this field is due to the racist that have so thoroughly muddied the water, but there is really little utility in it OTHER than assigning skulls to one group or the other in groups that are not otherwise different in much of a relevant degree. The motive behind this is usually racist to begin with.
