Serial murder is an example of the most extreme types of behaviour we see in human beings. It can be defined at a person who kills three or more people in a short space of time. But what really is a serial killer? Is it the way we were brought up that can lead to us becoming a serial killer? Or is there a serial killer gene?

Maggie Ritten Monday‚ September 30‚ 2013 Prof.Carrier Psych 108 In the articles I read‚ the origin of art is highly contested. However‚ that is irrelevant to the question of the evolutionary advantage of art creation. In strict Darwinian terms‚ selective advantage is a characteristic of an organism that enables it to survive and reproduce better than other organisms.1 Under this definition‚ there is a selective advantage for creating art. Creating art requires advanced cognitive dexterity
