Behavior
• Nature vs. Nurture…. What do you think?
How did

• The simultaneous presentation of two unrelated stimuli

Adaptive Mating Behavior
• Sexual Selection- adaptive changes in males and
females that lead to increased ability to secure a
mate
• Both sexes seek fitness which is the ability to
produce surviving offspring
• Because females produce few eggs they must be
very selective in their mate…Female Choice
• Because males produce infinite amounts of
sperm, they constantly compete to inseminate as
many females as they can
• How does this apply to both humans and
animals?
