Chapter 2: Evolution, Genetics & Experience
What makes you who you are?- your genetics?- your experience?
The nature/nuture debate (e.g, Trading Places)
Which matters more?- can you overcome bad genetics?- can you overcome lack of experience?
Is it physiological or psychological?
Dualism vs monism
“mind -stuff” vs “physical-stuff”
-do you have both?-can’t measure the “mind-stuff”

Make some observations regarding genetics & behavior
Evolution & Behavior
Evolution - natural selection
- social dominance- courtship displays
- its all about SEX - passing your genes on
Evolution - basic ideas
-Not a single line
- rapid or slow - depends on environment
- very few species still survive
- no preordained direction
- not all changes (structures/behaviors) are adaptive
- structural adaptations may change function
- functional relationships may not have genetic connection (convergent evolution)
Discovered in 1974 by Donald Johanson, Lucy is 3.5 million years old - A. afarensis
-a transitional form?
Big argument is which came first - big brain or walking upright?
Evolutionary Psychology
Mating is important- more about sex
Why different types of mating bonds? (think natural selection)
Polygyny - most common in mammals (selection)Polyandry? - not common (sea horses - very poor families)Monogamy - why?
- all with variations
