What factor influences primates’ slow life history
development and maintenance of large brains
Primate species in increasing order of relatedness
gibbons, orangutans, gorillas, bonobos, chimpanzees
Oldest known species in the human family tree
homo erectus
Hominin species with apelike brain size and bipedality
Australopithecus afarensis
Species nicknamed the Handyman
Homo habilis (used some of the earliest stone tools)
First species to exhibit modern limb proportions
Homo ergaster (African variant)
Homo erectus (Asian variant)
Insular dwarfism
small body sized evolved in response to constrained environments
Insular dwarfism species
homo floreseinsis
Ancestor of both Neanderthals and modern humans
Homo neanderthalensis
When did Neanderthals live
200,000 to 30,000 years ago (Pleistocene)
What environments were Neanderthals adapted to
colder environments
Evidence suggesting Neanderthals interbred with modern humans
non-African human population carry portion of neanderthal DNA
When and where did anatomically modern humans emerge?
200,000 years from Africa
When is there clear evidence of successful migration out of Africa
70,000
Sexual dimorphism increases or decreases from Australopithecus afarensis to modern humans
Decrease
What species migrated out of Africa 2 million years ago
Homo erectus
Which evolved first bipedal locomotion or large brain size?
Bipedal locomotion, answered using Australophithecus
What factor transforms the human environment during the Holocene?
Intensive domestication of plants and animals
Jealousy
state aroused by a perceived threat to a valued relationship
Jealousy function
motivates behavior to counter the threat
What sex difference in jealousy is typically focused on?
sex differences in threats and triggers of mate jealousy
David Buss predict what sex difference
sex differences in jealousy related to sexual infidelity vs emotional infidelity
Methods and results of Buss (1992)
Asked individuals which infidelity would be more distressing. Men reported sexual infidelity as worse, and women reported emotional infidelity as worse.
Methodological difference between study 1 and study 2 in Buss (1992)
study 1 used a survey, study 2 used electrodermal activity, pulse rate, and EMG to measure physiological arousal
Function of male sexual jealousy
combat the costs of unknowingly investing resources in another man’s child
Characteristics of a partner associated with increasing mate retention behaviors
presence or absence of competitors, mate value of potential competitors compared to husband’s, wife’s behavior, wife’s age, husband’s mate value, unfaithfulness, youthfulness, and physical attractiveness.
Characteristics of a partner associated with women increasing mate retention behaviors
income and status striving of the spouse
Male mate retention tactics
conceal partners, use intrasexual threats and violence
Association between spouse’s age and mate retention tactics among men
older their mate, less mate retention tactics
Association between spouse’s status striving and mate retention tactics among women
more status striving, more mate retention tactics
Evolutionary psychologists linked to theory of male sexual proprietariness
Daly and Wilson
Sexual proprietary male psychologies
solutions to adaptive problems of male reproductive competition and potential misdirection of paternal investments
Cross-culture practices of male sexual proprietariness
socially recognized marriage framed as property transfer, adultery laws and norms, legal recognition of infidelity as a special provocation to male violence, valuation of female chastity, reliable emergence of harems, practices such as veiling
Book regarded as beginning of Darwinian medicine
Why we get sick by Randolph Nesse and George C Williams
2 principles of Darwinian medicine
- do not view diseases as adaptations
- symptoms are evolved responses of the body and generally do have a function
6 reasons people have evolved vulnerabilities to disease
mismatch and infection (evolution takes time), constraints and trade-offs (evolution can’t do everything), reproduction and defense responses (evolution doesn’t care if you feel good)
Psychological disorders result of environmental mismatch
Substance abuse disorders, eating disorders, and attention disorders. Diet culture, media, trauma, and weight teasing are all environmental factors that led to psychological disorders.
Smoke detector principle
defense responses, including aversive emotions, evolved to minimize the fitness costs of signal-detection errors. results in selection for over vs under activation.
Wakefield’s definition of mental disorder
harmful dysfunction
4 categories of mental disorders
Genetic-based developmental disorders, disorders brought on by aging (senescence), disorders caused by mismatch, and adaptive responses that are aversive
Genetic based developmental disorder
bipolar disorder, pre-60, low prevalence, high heritability, psychiatric
Disorders brought on by aging (senescence)
Parkinson’s disease, post-60, low prevalence, low heritability, neurological
