Many behaviors are influenced by genes and can be inherited.

3. Innate and Learned Behavior
3. Behaviors can evolve under the influence of natural selection.
Organisms with an adaptive behavior will survive and reproduce better than organisms that lack the behavior.
These organisms have greater b_______ f_______.
(What’s the vocab word I’m looking for?)
4. After natural selection has operated for many generations, most individuals within the population will exhibit the adaptive behavior.

Examples of innate behavior:
the suckling of a newborn mammal
the weaving of a spider web

5. Innate and Learned Behavior
6. Innate Behavior = an instinct, or inborn behavior.
7. 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.
8. An instinct is NOT a reflex, which is a simple response of an organism to a specific stimulus.
contraction of the pupil in response to bright light
movement of the lower leg when the knee is tapped.
Example in the previous video with newborn piglets?

A change in behavior that results from experience is called learning.
Learning is also called acquired behavior.
