A % ¡ Mid parent B D 4. Why is sexual selection a form of natural selection? Do natural selection and sexual selection always act in the same way? What is an evolutionary constraint? How does their occurrence help answer the question whether all traits are adaptive? Read the article by Gould and Lewontin: 'The Spandrels of San Marco and the Panglossian Paradigm'. a. What is the most important criticism the authors put forward? b. Can you think of an example of 'adaptationism', and why that may or may not be correct? If you'd like, go ahead and post it on the Canvas discussion board!

Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.
