Q

what is cognitivism?

A

similar to nature v. nurture; not as concerned about being uptight about behaviour. Believe in the information theory. biologists used to dismiss cognitivism, claimed it had nothing to do with biology.

Q

What is cognitive ethology?

A

created by Griffin who was interested in beavers because they started covering noise making devices, showing that this behaviour is innate. cognitive ethology focuses on consciousness and mind.

Q

what is the difference between a reflex and a FAP

A

reflexes are simple motor actions, elicited by a sensory stimulus.
FAP’s are a complex motor act, involving a temporal sequence of component acts; generated by an internally or elicited sensory trigger

very hard to find a pattern in the occurrence of monogamy
differential observability:species, groups, individuals
identification of subjects

48
Q

A
  • chromosomal: non-viable/sterile hybrids
  • mechanical: morphological incompatibilities
  • incompatible reproductive rhythms
  • ecological: habitat incompatibilities
  • behavioural: specific recognition system
49
Q

what is evolution?

A

a change in frequency of alleles in a population over generations

50
Q

what are the three foundations of animal behaviour?

A
  • natural selection
  • individual learning
  • cultural transmission: social learning that will become transgenerational
51
Q

what are the 4 main forces of change in the evolution of behaviour?

A
  1. mutations
  2. gene flow: exhange of genes between populations of a species
  3. genetic drift: specific traits get over emphasized and you get something radically different from what you would find on the main land
  4. natural selection: fir or not fit; not fit features get dropped. need a passive agent (environment) and a selective agent (nature). need a trait that allows reproduction and survival
52
Q

what is indirect fitness?

A

when you have more environmental constraints you compete, mormota get social instead; darwainian was too focused on competition

53
Q

what are the 3 types of direct fitness?

A
  • traits improving chances of survival
  • correlated traits
  • sexual selection
54
Q

what does Gould believe about Neoteny?

Gould believes that humans unconsciously and naturally seeking neoteny. his example was the evolution of mickey mouse since its creation (juvenilization)

55
Q

describe lorenz on neoteny

A

feautures of juvinility act as IRMs for affection and nurtiring in adult humans. neotenic characteristics are designed to trigger oxytocin release in adults.

56
Q

what is heterochrony?

A

changes in time and order of developmental events. in dogs we have slowed down development.

Q

how is heterochrony applied to candids?

A

-changes in the time of onset of developmental stages
- changes in the rate of developmental stages
- changes in the number of developmental changes
less or slow = paedomorphosis
more or fast = peramorphosis

58
Q

what does Morey believe about dogs?

A

believes that dogs are paedomorphoc (compared to wolves)

59

65
Q

true or false behaviour is a phenotype?

A

true

66
Q

what is Morton’s law?

what is heterochrony?

A

changes in rate/time of development

what are facilitating factors (Hale)?

A

gregarity (no hierarchy within groups)
imprint
precociality (more likely to imprint)
paternal care or at least permanent presence around

72
Q

what is taxonomy?

A

the theories and techniques of naming, describing and classifying organisms

73
Q

what is taxinomy?

A

the study of the laws of classification

74

interest in broad questions

76
Q

what are some approaches in animal behaviour?

A

conceptual
empirical
theoretical

77
Q

A

Watson and Skinner

78
Q

ethology is historically __________

A

inductive (observations, theory making)

79
Q

who are the fathers of sociobiology?

A

williams, hamilton, Maynard Smith, Triver, Wilson, Dawkins

80
Q

what is Moynihan’s perspective of behavioural ecology and ethology?

A

behavioural ecology: strategies and environment

ethology: tactics and behaviours

81
Q

what are behaviour classification biases?

A

behavioural ecology: functions of behaviour

ethology: forms (ethogram), mechanisms and origins of behaviours

82
Q

A

models (often larger ones) that can evoke a stronger response

83
Q

describe stickleback sign stimuli

A

bolated belly of females stimulates reproductive behaviour and red belly of another male stimulates agression

A

studying species from the same genus

86
Q

what did Barash find in his study of marmots?

A

when less food avail. young will take longer to grow and mature, colonial system an advantage in cases of low food, aggressiveness is a key factor for dispersion

87
Q

what is an ethogram?

A

a catalogue of different behaviours

88
Q

what is direct development?

A

no larval stage, eggs hatch into small salamanders

89

A

species level adaptations

90
Q

what is individual learning?

A

individual-level adaptations; experience

91
Q

what are the two ingredients for natural selection?

A

trait (phenotype) ex. speed that are favoured and help the organism
selective agent ex. nature

92

variation
fitness
mode of inheritance
limited resources

93
Q

what are 3 types of direct fitness?

A
  1. traits improving survival
  2. correlated traits
  3. traits emanating from sexual selection
94
Q

what is artificial selection?

A

selective breeding. Humans selexting traits. ex. breeding border collies

95
Q

what is Kin Selection?

A

from Hamilton. individuals differ in their effects on the survival of their kin via their parental care/ helping behaviour. special case of trait/group selection. ability to know one’s kin -> MHC complex, uses sense of smell

96
Q

what did E.O Wilson believe about kin selection?

A

kin selection > group selection

97
Q

what did D.s Wilson believe?

A

reciprocal altruism exists as well as kinship altruism. depends on conditions

98
Q

A 
gene level
gamete level
individual level
mating pair level
immediate
99
Q

what did lorenz believe about neoteny?

A

features of juvenility act as IRMs for affection and nurturing in adult humans. we judge animals based on juvenility. we observe head, eyes, chin.

100
Q

what did Gould say about By-products of adaptations?

A

by-products of adaptations or “carry along traits”. traits that are not necessarily selected for or against. they’re just there. ex. tail bone, appendix
language is a by product of our large brains
hard to localize where it came from

101
Q

what is progressive fallacy?

A

some species have had more evolutionary changes than others, that does not necessarily make them better. not all changes are optimal

102
