Natural Selection can lead to Complex Adaptations “Will monkeys typing at random produce Hamlet,” Complex adaptations evolve through the cumulative retention of small changes. Apes have bigger brains:  They have recognition  Kinship Complex adaptations evolve in many small steps, each of which are favored by natural selection. Why use evolutionary theory to study human behavior?  Casual theories allow us to make predictions that can be tested with data.  Evolutionary theory is a broad casual theory  It compresses a diversity of sub-theories & hypothesis  The sub-theories are constrained to be consistent with broader theory Evolutionary science is controversial, but it shouldn’t be. The Naturalistic Fallacy: Makes a conclusion that things are the way they are, and should be. (Ex. Evolving to be Violent.) “Is” implies “ought” The Moralistic Fallacy: Cloud Judgment of the world is based off my own principles. “ought” implies “is” So, what causes people to hurt other people?

(Function)  Kin recognition & kin directed helping behavior Close inbreeding is avoided in all ethnographically studied cultures. Incest illicit the thought of disgust. (Mechanistic) Inbreeding avoidance is common in primates (Phylogeny)  Inbreeding avoidance is triggered by childhood propinquity (Mechanism/Development.)  Children raised in Kibbutz don’t marry each other (Development)  Inbreeding depresses fitness Evolution by Natural Selection  Transmission of traits  Genetic Variation  Competition for resources o Competition: Ability to populate o Variation: Ability to survive o Inheritance: Traits from parents to offspring Postulate 1: Environment constrains population growth.  Severe drought  Drought affected seed availability many birds died of starvation.
