>There is no research (to the best of my knowledge) claiming that there are biological differences between the same sex of different races.

Actually there are numerous observed differences in physical ability that are attributed to race, such as Tibetans having better adaptability to high altitudes than most other groups[1]. Physical differences are relatively uncontroversial, the problem arrives when we start to discuss mental differences.

I see not reason why a difference in environment would not cause various mental adaptations to form along the course of natural selection of geographically separate groups of people. This is an inconvenient idea and has been vehemently suppressed in the scientific community whenever it is brought up [2]. Instead of pretending such differences cannot exist we should instead focus on overcoming these differences so that everyone can participate according to their own unique ability.
