Trevor
Trevor is going for a run. He starts thinking about all the things that he needs to do throughout his day, and he decides that after he showers he will study for his midterm for a little while before he goes to work for the evening. As Trevor rounds the corner near home, he sees something move near his feet and then feels a sharp pain in his right leg. At this point, Trevor's heart rate increases substantially, as he spins away from the dog that just bit him. As the dog's owner apologizes and puts the dog back on its leash, Trevor's heart rate slows down and he then makes his way home.
What would an evolutionary psychologist say about Trevor's physiological responses to the frightening experience of being bitten?
