How did the discovery of DNA prove that Darwin’s theory of evolution was correct and how does it change the way we view evolution today and into the future?

Darwin’s theory of Natural Selection:  that all living things on earth shared a common ancestor. This theory was thought of as bizarre at first, but with later research seen to be true. After studying the DNA of apes, it was seen that human beings and apes were carrying many of the same traits. “Common traits” were seen through many other species as well.
