Bellwork: How many green stars do you see on each square? Black stars on each
square? What is this an example of?
Peppered moths are eaten by birds. The moth color varies from
light to dark. Light colored moths can blend in with a nearby
species of tree. In the 1800s factories released large amounts
of soot, which changed the tree color, so the birds were able
to more easily find the lighter moths instead of the darker
moths.

II. How
Evolution
Works
A. Artificial
selection:
selection by
humans for
breeding of
useful traits
1. The struggle for existence is
competition among members
of a species for food, living
space, and the other
necessities of life.
2. High birth rates and a
shortage of life’s basic needs
eventually forces organisms
into a competition for
resources.
B. Fitness: the
ability of an
organism to survive
and reproduce
1. Fitness is the
result of
adaptations.
2. Adaptation: any inherited characteristic that
increases an organism’s chance of survival.
a. Successful adaptations:
- enable organisms to become better suited to their
environment
- increase an individual’s ability to survive and reproduce.
Humans have thousands of adaptations: large brain,
opposable thumbs, excellent sensory organs, light, strong
skeleton, etc.
C. Natural selection: the process by which individuals with
characteristics that are not well suited to their environment
either die or leave few offspring.
1. Also referred to as survival of the fittest.
2. It is not seen directly, but only observed as changes in a
population over a long time.
3. Zombieland: The Rules
Essential Question
PG 89
What evidence supports the
theory of evolution?
Standard
B.7C - Analyze and evaluate how natural selection produces change in populations,
not individuals.
B.7E - Analyze and evaluate the relationship of natural selection to adaptation and
to the development of diversity in and among species.
A. Descent with modification: a
principle that says each living
species has descended, with
changes, from other species
over time.
1. It implies that all living
organisms are related
2. Also known as common
descent.
3. States all species were
derived from common
ancestors.
B. Darwin found evidence in:
1. the fossil record
2. the geographical distribution of living species (Biogeography)
3. homologous structures of living organisms
4. similarities in early development, or embryology.

Essential Question
What evidence supports the theory of
evolution?
C. Scientists use the fossil record
to help determine evolutionary
changes.
By comparing fossils from older
rock layers with fossils from
younger layers, scientists could
document the fact that life on
Earth has changed over time.
Researchers have discovered
many hundreds of transitional
fossils that document various
intermediate stages in the
evolution of modern species from
organisms that are now extinct.
Gaps remain in the fossil record. These gaps do
not indicate weaknesses in the theory of
evolution itself. Rather, they point out
uncertainties in our understanding of exactly how
some species evolved.

Essential Question
What evidence supports the theory of
evolution?
D. Homologous structures: structures that have different
mature forms but develop from the same embryonic tissues
are called (start similar, end different)
E. Vestigial organs are organs that serve no
useful function in an organism.
Something Important to Know:
Theory: a well-supported scientific explanation that is subject to
change.
Law: a scientific fact.
Evolution is a theory.
Evolution is often called “the grand unifying theory of
biology.”
Evolutionary theory continues to change as new data are
gathered and new ways of thinking arise.
