just because two species split doesnt mean there is a lot of genetical divergence. what has the most influence on genetics are the number of generations. for a meaningful change evolution has to go through many generations which are very long for humans compared to most animals so this means very long time spans measured in the hundred thousands. for changes that people think there are between human races much longer time spans would have been needed.
