Evolution Review Sheet


1. This term refers to a process of change in organisms over a period of time: . It states that present day organisms evolved from earlier, distinctively different organisms.


2. This term refers to when organisms with favorable variations reproduce more successfully than organisms with less favorable variations:


3. Organisms which share similar physical and molecular (genetic) characteristics have probably come from a .


4. Characteristics of a species that make its members better able to live and reproduce in their environment are known as


1. favorable adaptations 3. homologous structures

2. abiotic factors 4. biotic factors


5. Describe the first organisms on the Earth.


6. Many flies were present in the biology classroom. The teacher sprayed a pesticide to kill the flies. Unfortunately, some of the flies were still alive.

a. Why are some flies still alive?

b. If the pesticide was sprayed again, would it be more or less effective? Explain your reasoning.


7. What does the diagram to the left suggest?


1NAME DATE PREIB BIOLOGY MR DONATO EVOLUTION REVIEW SHEET . all develop at the same rate

2. evolved from different animals that appeared on Earth at the same time

3. all develop internally and rely on nutrients supplied by the mother

4. may have an evolutionary relationship, common ancestry



8. Provide one explanation why antibiotics do not work as well as they used to.


9. In order for evolution to take place there must be variation within a population. This variation is usually due to a mutation in the genes. In what organelle are genes located?


10. If a species lacks a good adaptation, what will most likely happen to it if an environmental change takes place?



WNAME DATE PREIB BIOLOGY MR DONATO EVOLUTION REVIEW SHEET ith medical advances, the US has been able to keep many bacterial infections at bay with the use of antibiotics. Yearly counts providing information on MRSA antibiotic resistance are represented in the graph to the right. 


11. Which statement best explains why some MRSA bacteria survive the antibiotics?


1. The weather in 2001 was probably warmer than normal.

2. In the last 20 years, fewer people wash their hands so they are more likely to get sick.

3. Environmental factors varied slightly as the years progressed.

4. Natural variation existed within the population.


12. What is the most probable reason for the decreased effectiveness of the antibiotics?


1. Antibiotics caused mutations in MRSA, which resulted in immunity.

2. Antibiotics were only used once.

3. MRSA bacteria resistant to antibiotics lived and reproduced.

4. Antibiotics chemically reacted with the DNA of the MRSA bacteria


13. Which species would be most likely to survive if there is a change in the environment? Why?

14. In terms of evolution, why is it “bad” to undergo asexual reproduction?


15. In order to have an effect on the evolution of a population, in what cells does a mutation need to be present in?


16. Use the following diagrams to answer the questions below.


NAME DATE PREIB BIOLOGY MR DONATO EVOLUTION REVIEW SHEET


a. List one organism that is extinct.

b. List one organism that is currently living.

c. Which organism is the common ancestor for all of the other organisms?

d. Which two species are most closely related – Q and R or Q and P?

Explain your reasoning.


1NAME DATE PREIB BIOLOGY MR DONATO EVOLUTION REVIEW SHEET 7. The Abert and Kaibab squirrels are closely related. The Abert squirrel is found on the South Rim of the Grand Canyon, while the Kaibab squirrel is found on the North Rim. Fur color is the only difference that can be observed between the species. An illustration of these two species is shown below.

Which statement best explains how the differences between these two species came about?


(1) Different adaptations developed because the abert squirrel preferred hotter environments.
(2) As the squirrels adapted to different environments, differences in appearance evolved.
(3) The squirrels evolved differently to prevent overpopulation of the habitat.
(4) The squirrels evolved differently because their ancestors were trying to avoid competition.


18. Harmful characteristics generally in frequency because they have a low survival value for the species.


19. Circle the correct terms to complete the statement. Extinction is most likely to occur when environment conditions (change, remain the same) and the majority of individual within a population (lack, possess) adaptive traits to survive and reproduce.
