Question 1
How is artificial selection different from natural selection?
Answer
Artificial selection is the only kind of selection that can occur in a laboratory.
Artificial selection is selection by humans rather than the environment.
Artificial selection changes traits but not genes.
Artificial selection can occur over one or two generations as opposed to many generations.

Question 4
Which of the following is the best test for the theory of natural selection?
Answer
Using artificial selection to produce different breeds of dogs
Exposing a population of rapidly replicating organisms to selection that kills a large percentage over the course of many generations, and then comparing the final generation to a population that was not exposed to the variable.
Observing a group of rapidly replicating organisms for many generations, and seeing if there was any change in their genes relative to the original population.

Question 5
Which of the following statements best describes the current knowledge about Earth’s biodiversity?
Answer
It is relatively common for scientists to discover new or fossil organisms that are completely different from other organisms.
Most species that have existed on Earth are alive today.
There is uncertainty about the diversity within various species.
Scientists generally agree that most species have been identified.

Question 6
Which of the following statements is true about a biological race?
Answer
Normally, biological races will evolve into separate species as time goes on.
Biological races can maintain their separate identities even if gene flow occurs frequently between them.
Biological races can be classified as more advanced and less advanced varieties.
Biological races form, similar to biological species, by restricting gene flow among groups.

Question 7
The “tree of life” model gives information about the ________.
Answer
the selection pressure that led to the divergence of a common ancestor into modern species
the precise time period during which organisms lived
relationships among species
geographic ranges of certain organisms
5 points
Question 8
Which of the following statements about the gene pool of a species is true?
Answer
The genes in a species are only part of a universal gene pool that encompasses all species.
The gene pool is different in different individuals of the same species.
Every individual of a species carries part of the gene pool for that species in its chromosomes.
Every individual of a species carries the whole gene pool for that species in its chromosomes.
5 points
Question 9
Which of the following statements represents evidence that supports the theory of common descent but specifically contradicts the hypothesis of separate types?
Answer
The fossil record provides substantial evidence that humans and chimps share a common ancestor.
Radiometric dating methods show that Earth is billions of years old.
Many genes found in humans are also found in yeast and they perform the same function in yeast that they do in humans.
The fossil record provides copious unequivocal evidence that the species that inhabit Earth have changed dramatically over time.
5 points
Question 10
Which of the following best describes why the process of evolution is easier to study in fruit flies than in birds?
Answer
Fruit flies have a much shorter generation time than birds.
Fruit flies are smaller than birds.
Fruit flies have a simpler diet than birds.
Fruit flies don’t live as long as birds.
