H)
On a clean sheet of paper, write your complete heading
Number your paper from 1 to 8 in the usual manner
Then go to your laptop, log on, & go to my website.
Take notes from my website (2 sentences per page)
Then complete the study guide at least twice
Next complete the class work with the CPS clickers
Then watch the Brainpop video called “Natural Selection”
Complete the Brainpop quiz for extra credit

Two type of adaptations:
(1) Behavioral- (what an organism does)
(2) Structural- (what an organism is…shape & form of the body)
Question: See the insects in the picture below. Can you see them?
Is this mainly an example of behavioral or structural adaptation?
This is mainly showing structural adaptation because these insects
have adapted by developing bodies that look like thorns.
This is called camouflage

Question: See the hibernating bear below.
Is this a behavioral or structural adaptation?
This is behavioral because it is what the animal does.

Two Key Behavioral Adaptations:
(1) Sexual Reproduction- (requires 2 parents: male & female)
(2) Asexual Reproduction-(requires only 1 parent)
Reproduces sexually
Zebra
Reproduces asexually

Key Adaptation Points
1) The process that drives structural change…
… is called natural selection
2) Structural changes and variation result from…
…sexual reproduction (over many generations)
3) Structural changes and variation also result from…
…genetic mutations (over many generations)
