You may have heard the theory of evolution, where humans evolved from apes. Well scientists are saying that we may not be done evolving yet. In fact, studies show that over the past 1,000 or 2,000 years evolution is accelerating. Scientists say that they can see changes in DNA studies. One hypothesis of why this might be happening is because of the worlds large population. The more people, the more likely a genetic mutation will arise.
