SELF STUDY GUIDE THEORY AND EVIDENCE OF EVOLUTION
UNIT objectives:
A) Be able to describe Darwin’s theory of evolution in terms of the 4 components that make up
natural selection and explain how natural selection can modify or change species over time.
(Pg 297-301)
B) Describe evidences for evolution including: fossil evidence, biogeography, embryology,
homologous structures, DNA comparison, protein comparison, and vestigial organs.
(Pg 302–307)
E) Define speciation and describe how reproductive isolation that can result in allopatric and
sympatric speciation. (Pg 326-329)
F) Explain how the use of genetics and the “molecular clock” has revolutionized species
classification and deepened our understanding of evolution (pg 341-345)
Vocabulary: embryology, homologous structure, analogous structure, vestigial, half life,
allopatric speciation, sympatric speciation, taxonomy, coevolution, convergent evolution
