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”
Is self-awareness something special?
Lose self awareness of own body - like neglect

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)
cladogram
Australopithecus - 6 million years ago
We started getting “homo” about 2 million years ago
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
Genetics
during meiosis
