We are related to apes

Kay seems to be going on an ape spree lately.  She's watched Gorillas In The Mist and Rise of The Planet of The Apes in the space of a few days. I've seen her devouring wiki articles on apes and hominids, too. She tells us that they are related to us. I was flabbergasted! How is that even possible. We're nothing like them.  She said that her species (homo sapiens sapiens, even though she sometimes like to say otherwise) and those apes descended from a common ancestor.  And since we are related to her, we are related to them, too. Actually I think if you go back far enough I'm sure we have a common common ancestor anyway.
