1. Classification and Evolution

2. 1.
The dodo bird was a flightless bird that became extinct in the last century. Although its disappearance had no significant recorded impact on other members of the ecosystem, it did affect what aspect of the ecosystem?
The ability for other species to adapt.
The genetic diversity of other species.
The biodiversity of the ecosystem as a whole.
The process of evolution within the ecosystem.

3. Use the following information to answer numbers 2 and 3.
A man-made lake in Oklahoma is filled with dead trees and construction debris remaining from the time of its construction. Over time, these items have become the natural habitat of the organisms living in the lake.

4. 2.
A new species of fish were transferred from a natural lake to the man-made lake, which of the following would be altered?
The fish’s ability to adapt
The genes of the fish
The ecosystem of the lake
The ability of other fish to adapt

5. 3.
The fish turns out to hungrily consume two other species of fish in the lake, eventually causing their extinction. What is a correct description of this circumstance?
The species diversity of the ecosystem initially increased, then decreased.
The genetic diversity of the fish initially increased, then decreased.
The genetic diversity of the ecosystem immediately decreased.
The species diversity of the ecosystem immediately decreased.

6. 4. Which structure is considered vestigial? Eye of a fly
Hip bone in a dolphin
Hand of primates
Toes on a goat

7. 1. Ideas about evolution Have already been thought.
Are perfect and need no refinement.
May change based on new data.
Only involve animals.

8. 2. What type of the following is the best example of microevolution?
A population of guppies gradually becoming darker
A group of plants developing thorns
A pod of dolphins hunting fish
A mosquito biting a deer

9. 1. What are the effects of genetic drift and gene flow?
Change in gene occurrences
Change in vision acuity
Change in DNA replication patterns
Change in organism size

10. 2. Which of the following are patterns of evolution?
Structural replication, reproductive homology, and special creation
Metabolic pathways, hormonal indicators, and genetic studies
Modern creationism, fossil theory, and punctuational model
Convergent evolution, coevolution, and divergent evolution

11. 3.
If two organisms evolve in response to each other, which evolutionary pattern is demonstrated?
Divergent evolution
Emigration
Coevolution
Convergent evolution

12. 4.
Darwin identified at least 13 different species of finch during his time on the Galapagos Islands. The main difference between the finches was the size and shape of their beaks. Which of the following statements best describes these differences?
The beaks are vestigial structures.
The beaks are analogous structures.
The beaks coevolved to suit their environment.
The beaks are homologous structures.

13. 1. Identify the evidence for evolution.
Cave drawings, ancient stories, and ceremonial rites.
Homologous structures, DNA, and embryonic evidence.
Eukaryotes, symbiosis and competition
Nephrons, antibodies, and homeostasis

14. 2. Natural selection states that individuals
With adaptive traits are more likely to survive.
On the bottom level of the hierarchy have the greatest reproductive success.
Demonstration altruistic behavior are the ones with the most mutations.
Remain unchanged over a period of time.

15. 3.
A mountain, ocean or ravine divides a population. After many years, the organisms show genetic differences from the original population. Which of the following explains how this change occurred?
Divergent evolution
Convergent evolution
Coevolution
Immigration

16. 4.
Humans have an appendix, a thin tube connected to the large intestine that serves no purpose and is a threat to human health and life if it becomes infected and/or inflamed. It is believed that the appendix once had a function as part of the human digestive system. The human appendix, therefore, is
A homologous structure.
A vestigial organ.
A vital organ.
A mutation.

17. 5. Brown bears and polar bears are examples of Coevolution.
Convergent evolution.
Divergent evolution
Emigration.

18. 6.
When certain insects and plants evolve in tandem, it is considered which type of evolution?
Coevolution
Convergent
Divergent
Natural selection

19. 7. Sharks and porpoises are a classic example of which concept?
Coevolution
Convergent evolution
Divergent evolution
Parallel evolution

20. 8.
Increased use of antibiotics has killed off bacterial populations that were most susceptible to antibiotic treatment. Consequently, many strains of bacteria are resistant to prescription drugs. What is the mechanism by which these resistant bacteria have been allowed to thrive?
Natural selection
Mutation
Speciation
Germination

21. 9. What is the ultimate result of bottlenecking?
It generates good competition.
It causes mutations.
It creates organisms that are genetically different.
It creates organisms that are genetically similar.

22. 10.
Why do scientists find it useful to use a classification system to group organisms?
Easier to learn about them
Helps avoid duplication of names
Organizes all information
All of the above

23. 11.
Which taxonomic classification below contains the fewest organisms?
