CHAPTER 22: Descent with Modification: A Darwinian View of Life
Directions
1) Before you read the chapter, decide whether you think each statement is true or false. Circle you
choice. If you are uncertain, write in a question mark and circle it.
2) As you read the chapter, identify whether each statement is true or false according to what you have
read. Circle the answer and note the evidence in complete sentences.
3) Was your thinking changed or reinforced by what you read? If so, in what way?
4) Be prepared to share your answers with the class.

True

Statement
True
False
2. Geologists Hutton & Lyell perceived that changes in Earth’s surface can result
from quick, discontinuous actions still operating at the present time.
Evidence:
True
False
True
False
3. Lamarck hypothesized that species evolve, and the mechanisms he proposed are
well supported by evidence.
Evidence:
True
False
True
False
4. Darwin’s voyage on the HMS Beagle provided much of the evidence for his
theory of natural selection. After returning to England he refined his theory and
published it in 1859 after learning Wallace had the same idea.
Evidence:
True
False
1. Darwin’s theory that the diversity of life has arisen from fewer ancestral species
through natural selection was a radical departure from the prevailing views of
Western culture.
Evidence:
After
Reading
True
False
True
False
5. Darwin recognized that there are heritable variations in populations and some of
these variations are better suited to a particular environment. Because organisms
tend to produce many more offspring than the environment can support, there is
competition for resources, and those better suited to a particular environment have
greater survival and reproductive success. Over time this process of natural selection
results in adaptation of organisms to their environment.
Evidence:
True
False
True
False
6. Scientists have never observed natural selection leading to adaptive evolution in
the environment or laboratory.
Evidence:
True
False
True
False
7. Evolutionary theory explains many kinds of observations, including structural and
molecular similarities, geographic distribution of organisms, and the fossil record.
Evidence:
True
False
True
False
8. Darwin’s theory of evolution by natural selection integrates diverse areas of
biological study and stimulates many new research questions.
Evidence:
True
False
