Example text

The generally accepted answer, for the majority of-if not all-evolutionary change, is the principle discovered by Darwin and called by him natural selection. If we first establish what natural selection is, it will become clear why it drives evolution. And we can then consider the importance of the principle for animal behavior. Natural selection is easily understood. Its operation follows logically from a series of elementary propositions. The first is that individuals within a species differ from one another; they show variation.

Chemical sense organs are found in many places in different kinds of animals. 6), which is a favorite animal for work on the nervous system, can smell seaweed, on which it lives. By recording the activity of the nervous system at different parts of the animal while it is smelling seaweed, it has been found that the chemical sense organs are in its tentacles. Houseflies have chemical receptors in their feet, which enable them to detect food (such as sugary water, in an experiment) by walking into it.

The nervous system is the main means of controlling behavior, and we begin by looking at how information is transmitted among the nerve cells. Information about the outside world enters the animal's nervous system through its sense organs. We consider sensory systems both in general and in one detailed example, the sonar system of bats. Much ofthe behavior ofanimals is neurofJhysiologically complicated, and we shall consider some examples of how animal senses have been successfully studied at a higher level than that of sensory neurons, and their behavioral choices at a higher level than the influence of neurons on one another.
