1

What are the four major categories of evidence for evolution from living species?

1

What are the two categories of comparative anatomy? (Explain what each means and how they show evidence of evolution)

1

What is comparative embryology? How does it show evidence of evolution?

1

Watch the video Rise of Mammals and answer the questions below.  The questions may not be in order in the video, so it is a good idea to read them ahead of time so that you know what you are watching for!

1

What are the two key points of Darwin's Theory of Evolution?

10

True or False: “Mutations are caused by selective pressure in the environment.”

10

True or False: “The same mutation could be advantageous in some environments but deleterious in others.”

10

True or False: “The appearance of dark-colored volcanic rock caused the mutation for black fur to appear in the rock pocket mouse population.”

10

Explain how the environment plays a role in changing the frequency of a mutant allele in a population.

1

Which of the following is an example of an adaptation?

1

Which of the following is an example of the bottleneck effect?

1

Which of the following is an example of the founder effect?

1

Categorize each item, you might use some answers more than once.

A hurricane wipes out the beach plants that have shallow roots, but the ones with deep roots survive
Can lead to a change in allele frequency
Leads to evolution
Caused by environmental pressure
Some seeds blow on the wind and end up on a new island
Some seeds have a mutation that makes them more sticky, so they are able to stay on pollinators longer
A hurricane wipes out half the beach rose plants on a beach
Completely random

Natural Selection
Genetic Drift

1

Individual organisms evolve.

1

In evolution, what does 'fittest' mean?

1

Do the fittest organisms always live the longest in evolution?

1

Which of these is a main reason why reproduction is an important step for evolution?

1

The change in populations over time.

1

A priest who served as a naturalist on the H.M.S. Beagle. Formed Theory of Evolution by Natural Selection.

1

A body structure in a present day organism that no longer serves its original purpose

1

A mechanism for change in populations where an organism with a favorable trait survives, reproduces, and pass the favorable phenotype to the next generation. Organisms without the favorable phenotype are less likley to survive and reproduce.

1

Body parts that do not have a commom evolutionary origin but are similar in function

1

Evidence of Evolution.......

1

Speciation can occur when a physical barrier divides a population.

1

Structural features with a common evolutionary origin

1

What is the term for a feature that allows an organism to survive better in its enviroment?

1

The hind leg bones in a whale are examples of

1

What is the process in which humans breed organisms for certain traits?

1

When the DNA of an organism is altered it is referred to as...

1

Which of the following is not an example of natural selection?

1

Two organisms that are closley related would have

1

Why are advantageous traits more likley to be passed onto offspring?

1

The ability of an organism to survive and reproduce in its specific enviroment

1

What happens in allopatric speciation?

1

Which of the following is an example sympatric speciation?

1

Which of the following describes geographic isolation?

1

Match the term to the definition

zygote		single-cell fertilized egg
