=Option E Neurobiology and Behaviour= =Introduction and Examples of Behaviour= State that behaviour in animals is related to the environmental context State that innate behaviour develops independently of the environmental context whereas learned behaviour reflects conditions experienced by individuals during development. Explain the role of natural selection in the development of behaviour patterns An organism may develop a certain behaviour which makes it better suited to its environment. For example a learned behaviour allows the species to obtain food with ease. Possessing a certain behaviour will increase the likelihood of a species and its offspring to survive and thus more and more of a species will develop this behaviour. Explain using species of birds or animals one example of each of the types of behavior migration grooming communication courtship and mate selection. Migration Arctic tern swallow white stork blue whale Grooming Rhesus monkeys will groom one another. This is a sign of respect as lower ranking members will groom higher ranking ones. Also grooming may be addictive for the monkeys due to the release of endorphins while grooming Communication bird songs alarm responses and hierarchal dominance patterns in wolves and red deer Courtship male display (ex peacock mallard duck great crested grebe blue footed boobie) Mate selection territory and song (birds) or combat (stags) Explain the need for quantitative data in studies of behaviour Studies of animal behaviour usually begin with careful observations from researchers. These careful observations allow us to understand the natural history of a species and often lead to the formation of a hypothesis. From here we can test the hypothesis by collecting quantitative data. Then according to this data we can then establish confidence levels for the data by statistical tests. =Perception of Stimulus= State that sensory receptors act as energy transducers Sensory receptors act as energy transducers. All sensory receptors convert energy from the ...
