• Many behaviors are influenced by genes and can be inherited.

Innate Behaviors
Behaviors can evolve under the ________________________________________________
_____________________________________________________________________________________.
Organisms with an adaptive behavior will ________________________________________
_______________________________________________________________________________________
After natural selection has operated for many generations, most individuals
within the population will exhibit the adaptive behavior.
Innate Behavior:
• ________________________________________ = _____________________________________________
________________________________________________________________________________________.
Behaviors appear in ____________________________________________________ form the first
time they are performed, even though the animal may have had no previous
experience with the stimuli to which it responds.
• An instinct is ____________________________________________, which is a simple
response of an organism to a specific stimulus.
•
•
All individuals will __________________________________________________________________
________________________________________________________________________________________.
Examples of innate behavior:
• ________________________________________________________________________
• ________________________________________________________________________
• ________________________________________________________________________
Learned Behavior:
• __________________________________________ - A change in behavior that results from
experience.
Many animals can alter their behavior based on experience.
Learning is also called acquired behavior.
•
The four major types of learning are:
1. ________________________________________________________________________
2. ________________________________________________________________________
3. ________________________________________________________________________
4. ________________________________________________________________________

______________________________________ - is a process by which an animal ___________
__________________________________________ its response to a repetitive stimulus that
neither rewards nor harms it.
 Example:
• _________________________________________________________________________________
_________________________________________________________________________________
 By ignoring a nonthreatening or unrewarding stimulus, animals can
spend their time and energy more efficiently.

_____________________________________________- Any time an animal makes a ________
_______________________________________________________________________________________.
• An example of classical conditioning is the work of _____________________
____________________________________.
•
___________________________________________ - occurs when an animal learns to
behave in a certain way through __________________________________, in order to
receive a reward or avoid punishment.
• _____________________________________________________________________________.
•
_________________________________________- reasoning, occurs when an animal
applies _______________________________________________________ to a new situation,
without a period of trial and error.
Example:

Young white-crowned sparrows have an innate ability to recognize their own
species’ song. To sing the complete version, the young birds must first hear
it sung by adults.
• Some __________________________________________________________________________________
during an early time in their lives. This process is called ________________________
• Imprinting keeps young animals close to their mother, who protects
them and leads them to food.
• Once imprinting occurs, ____________________________________________________.
• Imprinting can occur through ___________________as well as sight.
• Example:
• __________________________________________________________________________
When they are mature, salmon remember the odor of the stream and
return there to spawn.
