According to scientists, 90 percent of our DNA is “junk DNA.” The reason why they called it junk DNA is because they do not know its function. To call anything in our body “junk” is immature because nature will never create something that has no role to play in the evolution of the Universe. For example, if there is no reason for there to be a sun, nature will not create a sun because it will be a waste of energy. Our junk DNA is the more advanced DNA which holds the key to our true history and evolution. The reason why it does not seem to function is because it is turned off. This is necessary because our body has not evolved to the point where it can handle the functions of the junk DNA.
