Learning Guide: Natural Selection
Bill #3
To Think About: How is natural selection a major mechanism of evolution?
1st Read About: Darwin and Natural Selection Campbell’s Biology, 9th edition (2-sided column notes)
 pg. 452 Define evolution. Describe the difference between the pattern and process of evolution.
 Pg. 453-455 Describe Hutton and Lyell’s ideas and how they influenced Darwin’s thinking of evolution.
 Pg. 455-459
o Charles Darwin proposed that the mechanism of evolution is natural selection and that it
explains how adaptations arise. Explain what adaptations are and give two examples. Do
adaptations always have to be a physical characteristic?
o Explain the process of natural selection
o Describe the meaning behind this statement “In his book, Darwin
amassed evidence that descent with modification by natural selection
explains the three broad observations about nature…the unity of life,
the diversity of life, and the match between organisms and their
environments.”
o The picture at right is a drawing Darwin created to illustrate the idea
of common ancestry. Tape the picture in your BILL notebook, then
explain his idea, and justify your explanation with multiple examples
of supporting evidence.
o Summarize and use a diagram to illustrate each of Darwin’s
observations that drive changes of species over time and the two
inferences he made.
o Define artificial selection and give an example. Describe the reasoning Darwin used to explain
how long natural selection would take.
o Explain why populations are the smallest units of life that can evolve.
