Unit 6: Evolution
Theory of Evolution by Natural Selection
How are adaptations evidence of
natural selection?
adaptation (evidence of natural selection),
inherited variation
Darwin observed variations among similar
species.
Evolution is a theory and not a law or
hypothesis.
The components of natural selection are
overproduction, inherited variation,
competition, and selection of traits (natural and
artificial).
Survival of Fittest
Justify Darwin’s Theory of Evolution by Natural
Selection based on his evidence.
Justify evidence of evolution in the example of
antibiotic resistance.
Recognize the consequences of a species’
inability to adapt with a changing environment.
Recognize and explain how genetic variation and
environmental factors contribute to evolution by
natural selection.
Evidence of Evolution
What evidence supports the theory
that organisms change over time?
Fossil evidence is consistent with the scientific
theory of evolution that living things evolved
from earlier species.
homologous structures, extinction
Organisms that are closely related will have
similar DNA.
Understand the concept of relative-age dating
in relation to the fossil record.
Describe evidence of evolution including
homologous structures, fossil evidence, and
DNA.
