DARWIN’S VOYAGE OF DISCOVERY 16.1
The captain and his crew would be mapping the coastline of _________________________.
Darwin planned to collect specimens of _______________ and _________________.
In a single day’s trip into the _______________________ forest, he collected _______ species
of beetles and he wasn’t particularly looking for beetles!
Please explain Darwin’s theory of Biological Diversity. What are the 3 parts? How
are they explained? Please give examples for each
Darwin found fossils of many organisms that did not resemble any living species.
How might this finding have affected his understanding of life’s diversity?
Chapter 16 Guided Questions
Please explain why Darwin’s findings on the Galapagos Islands were significant.
Make sure to use the finches or turtles as examples to help explain your answer.
IDEAS THAT SHAPED DARWIN’S THINKING 16.2
Most famously, geologist ________________________ and __________________________ formed
important hypotheses based on the work of other researchers and on evidence they
uncovered themselves.
Lyell, who built on the work of Hutton and others, published the first volume of his
great work, ______________________________, in ____________.
What is the relationship between James Hutton, and geological features? Does this
help give evidence to the thought that the earth is really old, or the earth is relatively
young?
Chapter 16 Guided Questions
Explain Lyell’s principle of “uniformitarianism”. What is it? Why does it matter?
Jean-Baptiste Lamarck had several ideas that impacted Darwin’s thought process.
What were some of these ideas? Were all Lamarck’s theories flawless?

EVIDENCE OF EVOLUTION 16.4
What is Biogeography? What 2 patterns were significant to the theory presented by
Darwin? Explain each theory.
Geologists now use _________________________ to establish the age of certain rocks and
fossils. This kind of data could have shown that Earth is young. If that had
happened, Darwin’s ideas would have been ________________ and __________________.
Instead, radioactive dating indicates that Earth is about 4.5 billion years old –
plenty of time for evolution by ________________________ to take place.
Explain the difference between homologous structures and analogous structures.
How do these 2 different types of structures give evidence to Evolution?
(Remember to think of their structure and their function)
