Chimps evolving faster than humans?

Preliminary evidence shows that chimps have evolved and mutated faster than humans, which isn't all that surprising considering their life and mating cycle is slightly shorter, but apparently it looks like their genes mutate more each generation: http://www.timesonline.co.uk/tol/news/world/us_and_americas/article1662524.ece

More research will have to be done on this before anything clear comes out of this. For the moment, I'm not buying the big hoopla that people are trying to make out of this, that they're going to overtake us evolutionarily or something.
