What's the scientific reason that white and, to a lesser degree, Asian countries advanced far quicker and to a greater extent technologically than other countries? Especially when you consider that some of the unenlightened countries are the ones with greater resources and less challenges (such as harsh winters). Also, why did whites evolve a different skull shape to the their supposed ancestors in Africa? It makes sense that they would lose melanin to increase Vitamin D uptake but why would their skull shape change? Especially since we KNOW scientifically that all races are intellectually identical and that intelligence is an immutable characteristic of the human existence which has no causal relationship to brain shape or size except insofar as diagnosable mental illness and impairment is concerned which of course isn't to suggest that those races with smaller prefrontal cortexes are in anyway inferior or impaired?
