There are different skull shapes between races, so we we know there isn't a barrier. The brain is just another organ, why wouldn't it be susceptible to evolution?

  Evolution is slow paced. Such a change couldn't have happened in the last centuries or milennia. It'd take a longer time for it to cause a perceivable change.

    Second, evolution is slow, correct. But that hasn't stopped there from being obvious change. The brain is an organ, like any other organ, it evolves.
