25
What is the grandmother hypothesis?
The idea that menopause exists so that women can help their children reproduce
26
Stabilizing selection
Acts against both extremes in a distribution to keep population average
27
Directional selection
Acts against one extreme of a phenotype (ie. shifts toward the other)
28
Disruptive ("diversifying") selection
Acts against intermediate phenotypes (i.e. split in distributions toward extreme values)
29
Purifying selection (aka negative selection)
Conserves fixed trains and weeds out mutations at key loci
30
When does sexually antagonistic selection occur?
When the optimal phenotype is not the same for male and female offspring
31
What is the assumption of the adaptationist stance?
Phenotypes are adaptively constructed so we can hypothesize about how they increased ancestral fitness; if something common in species then it is probably designed that way because it solved an adaptive problem in an ancestral context
32
What are the strengths of the adaptationist stance?
- Can test different adaptationist hypotheses of adaptive origins - Adaptationist hypotheses are fairly straightforward to test
33
What is reverse engineering?
Looking at how something works and thinking about what function would cause it to have this design
34
What are the limitations of the adaptationist stance?
- Well-acknowledged constraints on optimal designs and genes underwriting them
35
Pleiotropy
Distinct phenotypic effects from same allele
36
Phylogeny fallacy
Belief that specification for an organism's particular phenotypic outcomes can exist independently of an in advance of real time developmental processes
37
What are the two sources of mortality?
- Senescence | - Extrinsic mortality
38
Senescence
Breakdown in biological function occurring as we reach maximum age
39
Intrinsic mortality
Death due to organism's aging processes ("natural causes")
40
Extrinsic mortality
Death due to environmental causes beyond your control
41
How long did the documented longest living human life?
122 years and 164 days
42
Disposable soma theory
Reproductive success higher when forgoing perfect self-repair in favour of reproduction
43
Trivers-Willard hypothesis
In bad times, it's better to have daughters, but in good times, it's better to have sons
44
Bateman's principle
Males gain more of a reproductive advantage from each individual mating partner than females do
45
Variance in reproductive success is greater in what sex?
Males
46
What are the only other species with menopause?
Pilot whales and killer whales
47
Direct reciprocity
Help if benefit to other is greater than the cost to self
48
Indirect reciprocity
Help those who have helped others in the past
49
What are some of the benefits for women of long-term mating?
- Physical protection for themselves and their children - Recurrent supply of provisions - Help with the socialization, training, and influence of their children
50
What are some of the benefits for men of long-term mating?
- Increasing their ability to attract a desirable mate - Increasing their paternity certainty by prolonged proximity and sexual access - Increasing the survival of their children - Increasing the reproductive success of their children - Increasing state sand coalition allies through their wife's extended kin
51
What % of mammalian species are monogamous?
3-5%
52
What are two common tactics men use in the "battleground" of pre-mating sexual conflict?
- Deception | - Sexual persistence
53
What are common tactics women use in the "battleground" of pre-mating sexual conflict?
- Frequency of sexual intercourse - Expenditures of pooled economic resources - Effort devoted to one set of kind vs the other - Amount of parental investment each allocates - Mating effort diverted to others outside the primary mateship
54
Men are particularly threatened by what kind of potential mate poachers?
Those who have superior job prospects, financial resources, and physical strength
55
Women are particularly threatened by what kind of potential mate poachers?
Those who surpass them in facial or bodily attractiveness
56
What kind of mating pattern do humans have?
Anisogamy
57
Anisogamy
2 sexes, fixed gamete sizes
58
Smith's "Twofold Cost of Males"
- Cost one: individual asexual clones reproduce twice as fast - Cost two: asexual females twice fitness of sexual ones due to genetic relation
59
Red Queen Hypothesis
Asexual reproduction will create essentially clones, because they have the same DNA, whereas sexual reproduction will create varied beings with different DNA
60
Sexual dimorphism
Phenotypic differences between females and males of same species
61
Sexual conflict theory
Potential selection for conflict in all phases of mating
62
Fisher's sexy son hypothesis
Any slight preference for ornament creates a positive feedback loop
63
The social-brain hypothesis is an explanation for what?
The fact that monkeys and apes have unusually large brains compared with all other mammals and birds
64
What is the explanation for large brains in primates according to social-brain hypothesis?
Primates need large brains because they live in usually complex societies that involve many interdependent relationships that change dynamically
65
According to SBH, how can the typical group size for a species be predicted?
From the size of its neocortex (especially the frontal lobe)
66
Humans typically have how many belief states?
5
67
Our social world naturally consists of how many individuals?
Approx. 150
68
Monogamy
Males and females have one mate only (at least per mating season)
69
Polygyny
A male and several females (harem)
70
Polyandry
A female and several males
71
Promiscuity
Multi-male (& multi-female)
