This information, and an acceleration happening faster in some groups, still can--and probably will--be used to support racist views.
I think that is a misinterpretation of the research. Racism against who? Chimpanzees? This research will most certainly finally put to bed the idea that humans and chimps are 98-99% genetically similar.
The Epigenetic code is also effected by the environment and changes based upon behavior. It will change the myopic view of genetics that has been used to dehumanize and disengage the responsibility of individuals from their actions. Epigenetics is going to usher in a revolution in thinking. Evolutionary theory will have to be changed significantly.
