So my question is this...how do you reconcile believing in racial "egalitarianism" (all races possess negligible differences in intelligence and aptitudes on average) with a non-theistic belief in evolution as a cold, non-supernatural process that doesn't care about fairness or equality? If test scores can be so much more dissimilar with full-blooded siblings than genetically identical twins how likely is it that populations of people geographically isolated for many millennia will possess the same levels of genes for high aptitudes and intelligence? I mean, if very small genetic differences between siblings can produce so much more variance than those of identical twins, then do you really expect different ethnic groups with their own distinct genes and physical features and different susceptibilities to diseases to have equal genetics for mental capacities?
Just saying, being a physicalist and believing evolution to be the sole source of what we are today has logical corollaries that might clash with your other beliefs.
