'Most detailed' map of the brain unveiled

I wonder if they considered the possibility of differences according to ancestral background. For instance, the most common type of blood in Peking Chinese is B, while the most common type of blood among caucasians is O, and the most common blood type among Hawaiians is A. The question needs to be asked, do different races have slightly different brain evolutions?
