All kidding aside, if you walked into a room already populated with a person and a chimpanzee, you would have no problem distinguishing between the two. Nonetheless, most scientific studies on the differences between human and chimpanzee DNA show a variance of somewhere between 1.2 and 2.7 percent. Despite there still being some expert debate on where in that range the number actually falls, regardless of who wins the argument, it is clear that the genetic difference between us and our nearest relatives in the animal kingdom is startlingly small. This goes a long way to explain the quality of television programming over the years.
