Substitute teacher tomorrow, Tuesday, Apr 12.
• Watching “Darwin’s Dangerous Idea”
• Completing the question worksheet.
PRIDE time for Wednesday, Apr 13 is flex time
Chapter 16 Introduction
Section 16.1 (Darwin’s Voyage of Discovery)
• What patterns of biodiversity did Darwin observe while
traveling aboard the Beagle?
Section 16.2 (Ideas that Shaped Darwin’s Thinking)
• How did other scientists’ work help Darwin develop his theory
of natural selection?
Section 16.3 (Darwin Presents His Case)
• What is Darwin’s theory of evolution by natural selection?
Section 16.4 (Evidence of Evolution)
• What are the main lines of scientific evidence that support
Darwin’s theory of evolution by natural selection?
Chpt 16 Vocabulary
Grab one vocabulary worksheet and pass the rest back.
• They will be due on the day of the exam.
• Should be completing as you encounter the words.
Evolution
Evolution?
• A process of change over time.
Darwin’s theory of evolution:
• Scientific theory (set of accepted beliefs)
• Explanation of how modern organisms evolved over
long periods of time through descent from common
ancestors.
pg. 450
Voyage of Discovery
Darwin’s journey began in 1831.
Travelled on the HMS Beagle.
Original expedition was to map the coastline of South
America.
pg. 450
Aboard the Beagle
What three patterns of biodiversity did Darwin observe?
• Species vary globally.
• Species vary locally.
• Species vary over time.
pg. 451-453

Entry Task
What did Darwin need before publishing his book?
• Evidence
What are some of the types used by Darwin?
• Geographic distribution
• Fossil Record
• Homologous Structures
• Early Embryonic Development
Housekeeping
Chapter 16 Quiz 1 on Tuesday, Apr 19.
• Darwin’s voyage & evidence of evolution
Substitute teacher on Thursday and Friday next week.
Learning Objective(s)
16.4.1 I will be able to explain how the geographic
distribution of species relates to their evolutionary history.
16.4.2 I will be able to explain how fossils and the fossil
record document the descent of modern species from
ancient ancestors.
16.4.3 I will be able to explain how molecular evidence
can be used to trace the process of evolution.
Entry Task
Similarities in bone structure between fossils and modern
organisms is used as evidence to support ____________.
Not just evolution.
• Common descent/ancestry.

Chapter 16 Quiz 1 on Tuesday, Apr 19.
• Darwin’s voyage & evidence of evolution
Substitute teacher on Thursday and Friday next week.
Geographic Distribution
Geographic distribution?
• Patterns in distribution of living and fossil species.
• Shows how modern organisms evolved from their
ancestors.
pg. 465
Geographic Distribution
Two patterns significant to Darwin’s theory:
• Closely related organisms differentiate in slightly
different environments
• Distantly related develop similarities in similar
environments.
pg. 465
Fossil Records
Fossil records?
• Use of recently discovered fossils forms series that
trace the evolution of modern species from extinct
ancestors.
pg. 466-467
Homologous Structures
Homologous structures?
• Structures adapted to different purposes as the result of
descent with modifications from a common ancestor.
pg. 468
Homologous Structures
Vestigial structures?
• Inherited structures that have lost their original function
due to different selection pressures.
pg. 469
Embryological Development
Embryology
• Similar patterns of
embryological
development provides
further evidence of
descent from common
ancestor.
pg. 469
Genetics
Genetics & Molecular Biology?
• Universal genetic code & homologous molecules
provide evidence of common descent.
Analyzing data (p. 470)
• Complete on a separate sheet of paper.
pg. 470
