The document discusses how studying the behavior of non-human primates and human primates in literature and films from the class can help explain evolutionary understandings of primate behavior. It notes that research on human and non-human primates may shed light on the theory of evolution since the primate lineage is thought to go back at least 65 million years. The author developed a thesis comparing the differences and similarities between non-human and human primate behavior and how this can lead to understanding evolution differently.
