DATE: 10/14/11 A/B DayLEQ: How is geologic evolution related to biologic evolution? 1. What is extinction? 2. A rock is dated between 300 and 500 years old. Is

this an example of relative or absolute dating?3. Explain your answer from #2.4. What is an index fossil?5. What is the difference between weathering and

erosion?

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.

• 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”)

What adaptations would increase survival in this environment?

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 green Xs’ 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?

1. What adaptation allowed one animal to eat more than the other?

2. Which animal would be favored (chosen) by the process of natural selection?

3. How would you predict these animals to evolve over time? (Would some become extinct?)

4. What change in the environment would make an animal with a different adaptation to survive?

(Ex: what would have to happen in the environment in order for the knife monster to survive?)

5. Do you think these animals had a common ancestor? Why or why not?
