Darwin
What vocabulary word describe "the complete death of a species?"
Extinction
Can a singular organism evolve?
No. Species evolve, but it cannot happen within one organisms life span.
What is the definition of a fossil?
Preserved remains of organisms or evidence of organisms.
Where would you more more likely to ONLY find simple organisms?
A. 1
B. 3
C. 5

Male brown lizards blend in better with the dirt, but brilliant male green lizards attract more mates. If a new predator bird is introduced to the ecosystem, what would you expect to see in the population of lizards?
Number of brown lizards will increase.
An organism's ability to blend in with their surroundings in order to escape predators is what kind of adaptation?
Camouflage
Name some things scientists can learn from a fossil.
Which layer of rock is the oldest?
Top, middle, bottom.
Bottom
An organism's learned behavior to move to a different location during certain parts of the year to increase the chance of survival, what is this type of adaptation called?
Migration
If an organism is unable to adapt to changes to the environment, what will happen to the species?
Extinction; death.
How does fossil evidence support the theory of evolution?
It's our LEQ!
Multiple answers may be accepted at the teacher discretion. Possible answer: serving as evidence that organisms have changed and evolved from previous organisms.
How does the Law of Superposition help scientist gauge the age of a fossil?
Depending on where the fossil was located the age can be estimated.
Giraffes have evolved to have longer necks over many centuries. How does this trait become present in the population?
Through mutations in DNA that proved to be beneficial therefore increased the chance of survival and reproduction. The mutation was passed on to offsprings.
Structures in different species that are similar because of common ancestry are known as.....
Homologous structures.
Around the world there is evidence of a KT boundary line in rock formations. This boundary is full of iridium which is not a substance that is found commonly on Earth. The dinosaurs fossils are present in rocks BELOW the KT boundary, but not above. Explain how this KT boundary gives scientists information about the dinosaurs.
Answers may vary. The KT boundary provides evidence about the mass extinction of the dinosaurs and suggests that something from outer space must have struck the Earth with catastrophic impact and world wide impacts.
Darwin's theory of evolution is like any other scientific theory which means it is still being studied. If new evidence is presented that doesn't agree with the theory of evolution what would need to happen?
The theory would need to be changed and improved.
Crabs have five legs, however, some crabs have different shapes to their 5th leg, it is flatter and more like a paddle. What possible reasons can you think of that would make this a favorable adaptation?

The discovery of the Tiktaalik fossil was pivotal to the fossil record because it was a transitional fossil. It had scales, four legs, and neck bones that indicated it could raise it's head. How does the Tiktaalik represent a transition?
**Show image #2 on the accompanying Google Doc**
Answers may vary. Possible answer: Tiktaalik was an example of organisms transitioning from sea/water to land-dwelling.
