Study Notes
Animal Behavior
- Animals are multicellular eukaryotes with a nucleus (mammalian red blood cells excluded)
- Animal behavior is coordinated internal activity, externally visible and responsive to changes
- Behavior is quantifiable—ethograms document observable actions
- Niko Tinbergen's philosophy: proximate (how) and ultimate (why) questions
- Ultimate: behavioral function and evolution; proximate: mechanism and development
Studying Animal Behavior
- Example: Larger roosters mate with more hens. Is comb color important for attractiveness?
- Hypothesis: Red comb color signals attractiveness.
- Experiment: Measure redness and preference.
- Method: Manipulate comb color, measure preference, analyze data
- Null hypothesis (H₀): No difference in attractiveness (A = B)
- Alternative hypothesis (H₁): Difference in attractiveness (A ≠ B)
- Methods to investigate:
- Observational: Causality unclear, used for describing patterns.
- Experimental: Clear causality, minimizing harm and replacing animals when possible
- Comparative: To understand evolution, compare closely related species
- Modeling: Predictions, meta-analysis
- Reduction: Use fewest animals possible
- Replacement: Use alternatives to animals when possible
- Refinement: Minimize animal harm
