Here is a rather good video by CrashCourse that explains evidence for evolution. It incorporates the DNA similarities between humans and all other animals as just 1 line of evidence to support Evolution.
Video is compliments of CrashCourse
To reiterate, yes Evolution is the thing, it did occur and is occurring still today through Natural Selection.
It has occurred over millions of years with every species that lived on Earth, and that is still living.
While not perfect, it is the most powerful biologic process ever discovered.
