Following Definition How is evolution defined?
Patterns What patterns in diversity over
time are produced by evolution? Mechanisms
How does evolution work? Microevolution How
does evolution work on a small scale?
Speciation What is a species and how do new
ones evolve? Macroevolution How does
evolution work on a large scale? Big Issues
What are the interesting questions about
evolution that are currently being investigated?

Click on Mechanisms then Descent Answer the
Following Which example of changes in a Beetle
population is an example of evolution. Explain
how this demonstrates descent with
modification. Diagram how this example of
beetle evolution could occur. Why are pink
flamingoes pink? Explain whether or not the
coloration of flamingoes is a result of
evolution. Click on Mechanisms then
Mechanism of Change Answer the
Following Describe and explain four mechanisms
of change of evolution. Click on
Mechanisms then Genetic Drift Answer the
Following Give an example of genetic drift.
Diagram to enhance your explanation.

Click on Mechanisms then Genetic Variation
Answer the Following What are three sources of
genetic variation in a population? Explain each
one. What does the Lederberg Experiment
conclude? What are two causes of genetic
mutations? What effects do gene flow have
of the evolution of a population? How does
sexual reproduction cause genetic
shuffling? Explain how ontogeny supports
the idea that living things share common
ancestors.

Click on Mechanisms then Natural Selection
Answer the Following Explain in detail how
natural selection works. Give an
example. Explain how artificial selection
differs from natural selection. What is
fitness? What are adaptations? Give three
examples of adaptations. Click on

Following Explain how micro-evolution differs
from macro-evolution. Click on Speciation
Answer the Following What is a
species? What causes speciation to
occur.
