Lecture 5-6 Flashcards
What’s the theory of evolution by natural selection? (changes in..) and what’s selective breeding?
Changes in species over time that transmits favourable traits throughout generations
Selective breeding produces the changes in organisms
what do fossil records show and what is evolution?
fossil records show gradual changes within organisms
evolution is changes in species over time
What did Darwin do and what occurred by three things..? (v,i,s)
Attempted to explain how and why evolution occurs by three things 1. variation 2.inheritance 2. selection
What are the three types of selections and what do they emphasize? (ns,sa,as)
- natural selection- emphasize survival traits
2.sexual selection-emphasizes reproduction traits - artificial selection-emphasizes intestinal human actions
What are the 6 general points on evolution? (doesn’t produce,trades,slow,cross..,produce as..)
And what three traits aren’t adaptions? (n,s,e)
Doesn’t produce strategic optimal designs
trade offs occur (1 trait for another)
evolution rate is generally slow but can be rapid
Cross species comparisons are important
Evolution can produce adaptions-heritable traits that positively impact
THREE TRAITS THAT AREN’T ADAPTIONS
1. noise-random variation
2. spandrels
3.exaptions
does evolution apply to physical traits as-well as psychological?
Yes as psychological traits are products of physical traits
what three animals can psychological traits be successfully artifically selected in?
1.dogs
2.cows
3. lab rats
What’s evolutionary psychology? (asks.. gives ev..) (underlying ev..)
Study of psychological phenomena in terms of underlying evolutionary mechanism
asks psychological question gives evolutionary answer
Give two examples on evolutionary psychological characteristics? (perce,bene diff) GIVE THREE EXAMPLES FOR THE SECOND CHARACTERISTIC (short,repro,costs dif)
1.perceptual characteristic- estimating height of cliff, we died a lot not being good at this so eventually due to natural selection and adaptions we are now good at this
- benefits differ dramatically between female and male
- short term mating between f and m
-potential costs differ
-reproductive potential
What was David Buss stussy and what did it show?
David buss casual sex proposition study, f and m walked around and asked randoms to have casual sex with them, 50 % of men said yes,100 % of women said no
how many different psychological trait adaptions are there just for short term mating between f and m ?
there’s 50 different trait adaptions
What are the 5 core psychological characteristics and why do they exist? and what does this require us to do in order to identify them? (COANE) (due to sel..faced) (requires us to.. identify two things and find..)
1.conscientiousness
2.openness
2.agreeableness
4.neuroticism
5,extra version
THESE EXIST due to selective pressure faced during species evolutionary history .
requires us to identify the adaption and pressure and relation between the two
