Study Notes
Ethology
- Ethology is the study of animal behaviors, particularly innate behaviors occurring in natural habitats.
Key Figures in Ethology
- Charles Darwin contributed to the scientific plausibility of evolution through the concept of natural selection.
- Konard Lorenz is recognized as the founder of ethology and was awarded the Nobel Prize in 1973 along with Nikolaas Tinbergen and Karl von Frisch.
- Nikolaas Tinbergen was a pivotal figure in modern ethology, known for his research on releasing stimuli and its effects on animal behavior.
- Karl von Frisch is famous for his research on communication in honeybees, particularly the discovery of the "waggle dance."
Imprinting and Behavior
- Imprinting is a phenomenon discovered by Lorenz through his studies of animal social relationships.
- Releasing stimuli trigger automatic, instinctual behavior chains in other individuals of the same species.
- Fixed action patterns are instinctual behavior chains activated by releasing stimuli, characterized by their uniformity and complexity.
Characteristics of Fixed Action Patterns
- Uniform across individuals.
- Commonly performed by most species members.
- More complex than simple reflexes.
- Cannot be interrupted once initiated.
Tinbergen’s Contributions
- Developed models in naturalistic settings to study behavior.
- Famous experiments involved stickleback fish and herring gull chicks.
- Introduced the concept of supernormal sign stimuli, which are exaggerated artificial stimuli that elicit stronger responses than natural stimuli.
Walter Cannon’s Concepts
- Coined the terms "fight or flight" and "homeostasis."
- Fight or flight refers to an animal’s internal state change in emergencies, prompting a choice between confronting or fleeing from threats.
- Homeostasis denotes the body's regulation to maintain stability and equilibrium.
Genetics
- Genes are the basic units of heredity composed of DNA molecules organized in chromosomes.
- The nucleus of human cells contains 23 pairs of chromosomes, defining genetic inheritance.
