,Chapter 1: Principles of Animal Behavior
1. How do Levitis and colleagues define animal behavior in their survey-derived consensus?
A. Muscular contractions triggered by involuntary peripheral sensory reflex arcs
B. Coordinated responses of whole living organisms to internal or external stimuli
C. Evolutionary changes in gene frequencies across successive generations of animals
D. Conscious motor decisions executed through complex central nervous system pathways
Answer: B
Rationale: Levitis and colleagues defined animal behavior as the coordinated responses of whole living organisms to
internal or external stimuli. This definition excludes purely developmental changes while capturing both overt actions and
physiological adjustments.
Keywords: behavior definition, Levitis, ethology consensus
2. What core characteristic did Niko Tinbergen emphasize in his early description of behavior?
A. Total movements made by the intact animal
B. Learned cognitive responses to environmental change
C. Internal emotional states driving purposeful actions
D. Shifts in population gene frequencies over time
Answer: A
Rationale: Niko Tinbergen broadly characterized animal behavior as the total movements made by the intact animal. This
historic description laid the groundwork for modern ethology by focusing on observable physical actions.
Keywords: Tinbergen, ethology, behavioral definitions
3. A researcher observes that herring gull chicks peck at red beak spots because retinal cones stimulate motor circuits.
, Which of Tinbergen's questions does this finding directly answer?
A. Adaptive utility across generations
B. Phylogenetic origin of pigmentation
C. Ontogenetic modification with aging
D. Proximate physiological mechanism
Answer: D
Rationale: Investigating neural circuits and sensory receptors that trigger an action addresses Tinbergen's mechanistic
question. This represents proximate causation by explaining the immediate physical machinery generating the behavioral
response.
Keywords: Tinbergen questions, proximate causation, sensory mechanism
4. An ornithologist finds that gull chicks pecking red beak spots receive significantly more regurgitated meals from
parents. How should this evolutionary explanation be categorized?
A. Immediate sensory triggering mechanism
B. Ultimate explanation of survival value
C. Ontogenetic shift in adult feeding
D. Cultural transmission between generations
Answer: B
Rationale: Demonstrating that a behavior increases nutrient intake and fledgling survival addresses Tinbergen's question
of survival value. Ultimate explanations focus on how behavioral traits influence reproductive success and Darwinian
fitness.
Keywords: survival value, ultimate causation, adaptive significance
5. One biologist asserts that male sparrows sing in spring because rising testosterone binds to receptors in song control
nuclei. Another biologist argues that sparrows sing to repel rival males and defend nesting territories. How should these
two assertions be synthesized?
A. They represent complementary proximate and ultimate explanations of behavior
