There's certain small things that are adaptations of the environment
If you are darker-skinned, you will thrive better in the tropics than lighter skinned people, because your dark pigmented skin is an adaptation that gives you natural defense to strong sunlight. In contrast, being lighter skinned is better for living in higher latitudes where there is less sunlight, as you gain vitamin D from the sun more easily (but get too much sometimes and burn, so not good for the tropics).
If we're talking things like athletic ability, intelligence, etc then there's no one group who are superior. Things like IQ and physical health are more to do with upbringing, wealth and status and environmental factors than with genetics (not always, but most of the time).
Is there a superior race?
