Natural selection Adaptation Niche Competition Predation

Slide 24

Adaptations = traits that an organism had to eat, grow, or reproduce Some are better than others!

Slide 25

BEHAVIORS Migrate v. stay in environment Strong sense of smell v weak sense of smell PHYSICAL TRAITS Long tongue v short tongue Bright wings v dull wings Wide span wings v short wings

Slide 26

Slide 27

Natural process The strongest adaptations will allow for survival The weaker adaptations will result in death!

Slide 28

Slide 29

Natural selection assumes that the weaker traits or behaviors will cause a part of a species to die out!
