Not sure what exactly you mean by this. If you mean that the idea of "more highly evolved" is meaningless in evolutionary theory, you are quite correct.
If you mean that evolutionary theory does not allow for the possibility that some "races" or sub-species of humans will develop average characteristics that differ from the average characteristics of other "races," then you are quite incorrect. In fact, such differentiation is exactly what separates one "race" from another.
Given the fact that races differ from each other, there is no evolutionarily valid reason for assuming in advance that such differentiation cannot include intellectual and character aspects. In fact, a logical person would expect such differences.
Careful measurement has the potential to prove or disprove that such differences exist, but saying in advance that they cannot exist is an act of faith, not of science.
Differences do not imply superiority or inferiority, and especially not that one group has more of that evolution stuff and the other less. Europeans are evolved to live in Europe, drink milk and absorbe sunlight in northern climes. New Guineans are evolved to filter out excess sunlight and better dispose of heat rather than conserve it. Both are regional adaptations brought about by evolution to each particular environment.
