Unit 8: THEORY AND EVIDENCE OF EVOLUTION
UNIT OBJECTIVES:
A) Be able to explain Darwin’s phrase “Descent with modification”. (Pages 299-301)
B) Describe the components of Darwin’s theory of natural selection. Explain how Darwin’s natural selection
differed from Lamarck’s theory of evolution. (Pages 297-301)
C) Be able to explain how “transitional species” in fossil record can be used as evidence for evolution.
(Pages 302-305)
D Be able to explain how a fossil can be dated using isotopes and radiometric dating. (Pages 282-284 Ch 14)
E) Describe several different types of evidence for evolution. (Pages 302-307)
F) Be able to explain divergent evolution, adaptive radiation, and co-evolution. (Pages 308-311)
Vocabulary: natural selection
