Study Notes
Animal Behavior
- Animals exhibit various behaviors, including interaction with each other and their surroundings.
- Ethology is the scientific study of animal behavior, focusing on natural environments rather than controlled settings.
- Ethologists address four key questions about behavior: causes, triggers, anatomical and functional involvement, and developmental aspects.
Factors Influencing Behavior
- Natural Selection: Behaviors that enhance fitness are more likely to persist over generations, while maladaptive behaviors diminish.
- Nature vs. Nurture Debate: Animal behavior is influenced by both genetic inheritance (nature) and environmental experiences (nurture), with most behaviors resulting from a combination of both.
Examples of Behaviors
- Social behaviors, such as pack hunting in wolves, improve survival rates and genetic continuation.
- Alarm calls in squirrels serve a protective function for others but may risk the calling squirrel’s safety—this paradox can be explained through kin selection.
Kin Selection
- Kin selection is a natural selection process where behaviors that aid close relatives increase the likelihood of shared genes being passed down.
- This explains seemingly self-sacrificial behaviors that benefit the survival of genetically similar individuals.
Special Cases of Behavior
- Unique animal behaviors, such as those exhibited by electric eels and octopuses, highlight the diverse adaptations animals employ for survival and interaction.
Summary of Key Concepts
- The development of most animal behaviors results from a mix of genetic influence and environmental exposure.
- Fitness-enhancing behaviors are favored by natural selection and evolve accordingly.
