Study Notes
Animal Behaviour
- Animal behaviour is an action carried out by the muscular or hormonal system, controlled by the nervous system, in response to a stimulus.
- Animal physiology contributes to behaviour, and behaviour influences physiology.
- Behaviour is essential for survival and reproduction, and is subject to selective pressure during evolution.
- Behavioural selection affects anatomy because body form and appearance are important for recognition and communication.
Brief History of Animal Behaviour Study
- Early ethologists studied behaviour for practical purposes, such as hunting prey.
- Natural theologians in the Middle Ages documented behaviour as part of general biology.
- Animal behaviour became a formal discipline from the early 1900s.
- Modern studies of animal behaviour emerged in the late 1900s and early 2000s.
The Study of Animal Behaviour
- Understanding animal behaviour helps understand animal actions, including human actions.
- Behaviour links the nervous system to the external world.
- Behaviour is how an animal establishes and maintains its ecological niche.
- Animal behaviour results from complex interactions between genetic and environmental factors.
What is Behaviour?
- Behaviour is what an animal does and how it does it.
- It's a result of genetic and environmental factors.
- It's essential for survival and reproduction.
- It's subject to natural selection.
Natural Selection
- Natural selection is the process through which species adapt to their environments.
- It drives evolution.
- Organisms best adapted survive, reproduce, and pass on their traits to the next generation.
Stimuli
- A stimulus is any change in biotic or abiotic environments that elicits a reaction or response in a living organism.
- Stimuli can be internal (e.g., hunger, thirst, pain) or external (e.g., predator sound, potential mate, changes in day length).
