2) The process that drives variation…

3) Changes and variation result from…

4) Changes and variation also result from…

…sexual reproduction (over many generations) and changes in the environment

…genetic mutations (over many generations)and changes in the environment

… is called natural selection

organisms must change (adapt) by either changing their behavior or changing their body structure or both.

Notes Science

1) When environmental changes occur…

SPI 0807.5.2 Adaptation

Two types of adaptations: (1) Behavioral-(2) Structural-

Look at the image of the hibernating bearQuestion: Is this a behavioral or structural adaptation?

(what an organism does)(what an organism is…shape & form of the body)

This is behavioral because it is what the animal does.

SPI 0807.5.2 Adaptation

Notes Science

Two Key Behavioral Adaptations: (1) Sexual Reproduction-(2) Asexual Reproduction-

(requires 2 parents: male & female)(requires only 1 parent)

SPI 0807.5.2 Adaptation

Notes Science

Reproduces sexually

Dogs Hydra
