Bio1100 Chapter 37 Behavior and the Environment
  1. Animal behavior   is defined by response to stimuli   in the environment.

     
  2. An innate   (instinctive) behavior is inherited through genes, as when a sign   stimulus triggers a fixed action   pattern (FAP).

     
  3. Many behaviors are learned   and can be altered based on previous experiences.

     
    • Associative   learning takes place when a behavior is conditioned   by associating either a stimulus or a behavior with a consequence.





       
    • Many animals exhibit imprinting   during an early stage of development called the critical   period.


     
  4. Some animals are capable of complicated behaviors called cognition  .

     
  5. Sexually reproducing animals often exhibit reproductive behaviors that result in sexual   selection.
     
    • In many species, females choose their mate in a process called intersexual   selection.

       
    • Males often compete   for females in a process called intrasexual   selection.


     
  6. Animals that live in social groups must communicate   with each other.







     
  7. Some social animals exhibit altruistic   behavior, an action that benefits other individuals at a cost to the actor.

     
  8. Altruistic behavior may have evolutionary adaptations due to kin   selection.
