Describe "junk DNA" and how ongoing genetic studies may help reveal how it functions in important ways

However, recent research has found that long stretches of junk DNA are shared by humans and other animals, such as mice. This finding suggests that this DNA is not unimportant, but that it may in fact play a valuable role in biological functions such as aging or disease.
