Prerequisite(s): BIOL 230 or PSYC 203. When the animals came to be in the Pre-Cambrian, two developments were about to become realized: Social Interactions and Nervous Systems. There were many reasons for this including the rise of predator/prey relations, the emergence of sexual reproduction, colony formation etc. In the Animal Kingdom, how organisms interact with others is critical to understanding behavior, anatomy, and physiology. We will, in lecture and reading, focus on the nervous system and how it relates to inter and intra species interactions in humans and non-humans. We will integrate neuroscience, social psychology, genetics and evolution so that one will understand the how and the why social interactions look like they do.
