Worksheet time: 4hrs 10mins
How do most fossils form?
An insect becomes trapped in amber.
An entire organism becomes frozen in ice.
A dead organism becomes buried in sediment.
A dead organism becomes buried in tar.
How does the fossil record help to support the theory of evolution?
the fossil record shows that organisms slowly change over time
The fossil record shows that species evolve very quickly
The fossil record does not support the theory of evolution
Which rock layer most likely contains fossils of the oldest organisms?
1
2
3
4
If scientists found this fossil, what could they infer?
what fish are like today
that this fish lacked oxygen
that water once covered the area where this fossil was found
According to the law of superposition, the oldest fossils are found
At the top of the rock layers
Near the bottom of the rock layers
Somewhat near the surface
Which rock layer contains the newest fossils?
B
C
D
E
F
What are the oldest fossils and why?
B, C- because they are closest to the top
A, B- because they are closest to the bottom
They are all the same age- because they are all found on layer 2
A, B- because they are found closest to the top
When did fossil A become extinct?
Layer 1
Layer 2
Layer 3
Layer 4
Fossil A is an ancient mollusk, an organism that needs water to survive. Why do you think that the mollusk went extinct in this particular sample of the fossil record?
When the ocean levels rose in layer 4, the mollusk went extinct because they cannot live in water
For some reason, the ocean disappeared causing the mollusk to thrive
For some reason, the ocean disappeared causing the mollusk to go extinct
When the ocean level rose in layer 4, the mollusk thrived because they need water
In which layer did fossil C come into existence? How do you know this?
Layer 1-Because that is the layer it is first seen
Layer 1- Because that is the last layer it is seen in
Layer 2- Because that is the layer it is first seen
Layer 2- Because that is the last layer it is seen in
The evolution of the horse is the most complete fossil record we have of a single organism. Using the picture, what can you conclude happened to the horse over time?
The horse grew larger and lost its toes
The horse shrank and lost its toes
The horse grew larger and gained toes
The horse shrank and gained toes
How do whales benefit from a nostril at the top of the head?
It doesn’t interfere with the eyesight of the whale.
The whale can eat under water without choking.
The whale doesn’t need to breathe air because it has gills like fish.
The whale can use the nostril to snell prey so that it will not starve.
What is common ancestry?
When a species no longer exists
When organisms are descended from a single ancestor
The earliest organisms were ___________; the more recent organisms are ____________.
simple; more complex
complex; more simple
Which of the following terms describes when a new species evolves or develops?
Unifornitarianism
Speciation
_______________, or selective breeding, is one way that humans impact evolution. One example is how the Belgian Blue cow has been bred to have greater muscle mass.
Artificial selection
Homologous

Dark moth
Light moth
Both will be equally successful
Neither will be successful
A mutation causes a new fur color variation to appear in a mouse population. In which of the situations described below would the new fur color become more common than the old color in the mouse population?
If plenty of food is available in the mouse habitat.
If the new fur color gene is a recessive allele.
If the amount of reproduction in the mouse population stays the same.
If the new fur color gene is helpful in the survival of mice and their offspring.
The formation of a new species is called
Natural selection
Struggle for existence
Speciation
Darwinism

What is an adaptation?
A variation that helps an animal survive.
The food that an animal eats.
