Chapter 34
Animal Behavior
In this chapter, students
will read about the major types of innate and learned animal behavior
and the significance of behavior as part of a reproductive strategy and
a broader ecological adaptation. The links below lead to additional resources
to help you with this chapter. These include Hot Links to Web sites related
to the topics in this chapter, the Take It to the Net activities referred
to in your textbook, a Self-Test you can use to test your knowledge of
this chapter, and Teaching Links that instructors may find useful for
their students.
Section 34-1: Elements of Behavior
When an animal
responds to a stimulus, body systemsincluding the sense organs,
nervous system, and musclesinteract to produce the resultant behavior.
Innate behaviors
appear in fully functional form the first time they are performed, even
though the animal may have had no previous experience with the stimuli
to which it responds.
The four major
types of learning are habituation, classical conditioning, operant conditioning,
and insight learning.
Section 34-2: Patterns of Behavior
Many animals respond
to periodic changes in the environment with daily or seasonal cycles of
behavior.
To pass along
its genes to the next generation, any animal that reproduces sexually
needs to locate and mate with another member of its species at least once.
Courtship behavior helps many animals identify healthy mates.
Usually, members
of a society are related to one another. Related individuals share a large
proportion of each other's genes. Therefore, helping a relative survive
increases the chance that the genes an individual shares with that relative
will be passed along to the next generation of offspring.
Animals may use
visual, sound, touch, or chemical signals to communicate with one another.
