CONTEXT CLUES:
1. My ancestors were American Indians. Even though I do not speak the native language, I am so proud of my ancestry!
2. My dog’s offspring all look exactly like my dog! Even though they are still puppies, they have the same spots!
3. Over time, my opinion has evolved. At first, I thought the Mavericks were going to win, but not I think the Lakers are going to win.

HOT QUESTION #2
• Fossils have shown that ancient frogs had gills similar to modern day fish. This fact can be best explained by which of the following:
a. radiometric datingb. extinctionc. evolutiond. climate change
You should be:
Natural Selection Example
• Which rabbit has a better chance of surviving in the North Pole? Why?
• Thinking silently.
All the brown rabbits die
Only one white rabbit dies
White rabbits have babies
Now we have ALL white rabbits!
PEPPERED MOTHSpre-industrialization
Which moth would be more likely to survive? WHY???
PEPPERED MOTHSpost-industrialization
Which moth would be more likely to survive? WHY???
Biologic Evolution: the ways that species change over time
Geologic Evolution: the ways that the earth changes over time
Natural Selection:Adaptation: a physical trait inherited from a common ancestor
Natural Selection: certain traits that help a species survive become more common over time (also called “Survival of the Fittest”)

Pick a card, any card!• 1: Your environment temperature increases & green
fur is too dark. Your species becomes extinct. • 2: A new predator has invaded your environment.
This predator eats yellow species. If you have a yellow card without an X on it, sit down. If you have an X, you adapted strong leg muscles and outran the predator.
• 3: There was a flood that wiped out Reds’ food sources. You couldn’t adapt fast enough! You go extinct!
• Everybody that’s left survived. You adapted to the changing environment!
1. What were the different adaptations?2. How did your environment change?3. In the end, which adaptations were
“naturally selected”? (Which species was the fittest for the changing environment?)
4. Do you think that all of the species had a common ancestor? Why or why not?
