Have you ever…?

Have you ever had the experience of looking into the eyes of the chimpanzee or gorilla at the zoo, or if you're really lucky on safari, and thought, "those eyes looked remarkably like my eyes", and "those hands look remarkably like my hands", and "those genitals looked remarkably like…" well you get the idea. If you have both these thoughts and wondered,"where do I come from?" you are not alone.
