The difference between races and ethnicities is largely:
(a) Neoteny: morphology, behavior (Domestication)
(b) Average IQ (Intelligence)
(c) Verbal-Spacial Bias in IQ (ex: Ashkenazi vs Eas Asian)
(d) Religion, Tradition, and Culture (fixable with time)
(e) Utility of ingroup bias (ethnocentrism) in when politically intermixed. ( Unfixable )
Almost everything else is irrelevant.
