Genetics and evolutionary foundations of behavior Flashcards
How much do human’s genes match Chimpanzees
98.8%
-Psychological structure
-traits/Tendency
-Influence behavior, not directly but indirectly
Genes
-anywhere its the same
Specietypical
-information
-have gene segment
-affect development
DNA
-a change to gene’s DNA sequence to produce something different
-A mistake
Genetic Mutation
-with high hormones, gives more stress
-usually found in coffee
Cortisol
-to modification on as a result of changed life circumstance
Adaption
-refers to the set of genes that the individual inheritsSGe
Genotype
-the observable properties of the body and behavioral trait
Phenotype
-environment effect to genes
-gene regulating activity that doesn’t involve changes to the DNA code and that can persist through one or more generation
-We inherit from our parents not only DNA
Epigenetics
-many genes are needed behavior traits
-One gene is not enough
Polygenic
-Have different level of spectrum
-Ex. Depression
Continous
-very specific
-in or you’re out
Categorial
Genetics can be distinguish between
-Coding genes
-Regulatory genes
-codes for unique protein molecules
Coding genes
-Help activates or suppress specific coding genes and thereby influence the body’s development
Regulatory Genes
-does not alter the protein with a gene will produce but rather influences whether the genes will produce the protein at all
DNA Mythelation
-do not produce their proteins that is they are “shut off”
Mythelated genes
-occurs in sexual reproduction
Reshuffling of genes
-errors that occasionally and unpredictably occur during DNA replication, causing the “replica “ to be not quite identical to the original
Mutations
-Natural theologian
William Paley
-Evolution
-Natural selection
Charles Darwin
-Selfish Gene
-Blind watchmaker
Richard Dawkins
-the long-term adaptive process spanning generations that equips species for life in its ever changing natural habitat
Evolution
-Variation due to chance alone without selection
Genetic drift
-has designs with purpose that had been passed around
Ancestral
- ‘what ever natural is good’
Natural fallacy
-assumption that genetic influences on our behavior take the form of genetic
Deterministic Fallacy
Genetic variability two main sources
-Reshuffling of genes
-Mutations
-some traits that evolved because they served the needs of our ancestors are no longer functional today
Vestigal Characteristics
To survive apes & Monkeys cling onto their mother’s fur in evolution, we los our fur so infants cant clinv onto us anymore, however the reflex remain
Grasping reflex
Usefulness
Functionalism
-Explains ultimate cause for a phenomenon in evolutionary sense
-what happened 1000 years ago
-explains how genetic info. Is passed onto generation
Distal explanation
-what happened seconds ago
-biopsychosocial model
Proximate explanation
