13.1 The Theory of Evolution
1. Identify two specific observations that led Darwin to conclude that species
evolve.
a.
b.
2. What is the process (often referred to as the ‘mechanism’) of Darwin’s agent
of change?
c. Define it.
3. Define: Evolution
4. What is ‘adaptation’. Give an example.
5. Write the four parts to Darwin’s Theory of Evolution:
a.
b.
c.
d.
Darwin’s Ideas, Updated: Change within a population
6. __________________________causes frequency of certain alleles in a population to
increase or decrease.
7. __________________________ and ______________________ provide endless source of
variation.

8. _______________________
_______________________ is when two populations of the
same species do not breed with each other due to geographic separation.
Ex: ___________________________________ and ___________________________
Tempo of Evolution
9. ____________________________ and _____________________ _____________________________
are two types of evolution based on how long changes take to occur.
13.2 Evidence of Evolution
10. What are three sources of scientific evidence supporting evolution?
_____________________________ ______________________ and _______________________________
Give ONE example:
13.3 Examples of Evolution
11. _____________________________’Key’ lesson learned…this is what dictates direction
and amount of evolutionary change.
12. The four factors of Natural Selection are:
a.
b.
c.
d.
13. Antibiotic resistant ___________________________________ is an example of a disease
that has evolved through natural selection.
14. Darwin noticed nine species of finches that appeared to have evolved from a
single, mainland species. The main differences in these species was in their
_________________________________________ because of the ___________________they ate.

Formation of New Species
Page 3
15. _____________________________ is the accumulation of differences between groups,
and ____________________________________ is the process of formation of a new
species through divergence.
16. Look at Fig 14, p. 291.
____________________________________is the first thing I notice that’s different about
the frogs when I just look at their pictures. When I read the graph, I notice
that the four different frogs have different _____________________________ times,
which means that they can’t reproduce together, even if the WERE the same
species!
*Find out how these affect species. Ask your teacher to review this with the
class. Founder Effect, genetic drift and migration
Evolutionary History, p. 307-310
17. ______________________________ is a way of organizing and grouping organisms
based on their evolutionary history.
18. __________________________________ ______________________________ is when
similarities evolve in organisms that are not closely related to each other,
often because the organisms live in very similar habitats.
19. _______________________________ characters are similarities that arise through
convergent evolution.
20. This is used to study phylogenies of shared characteristics __________________.
21. A backbone is an _______________________________ character of both birds and
mammals.
22. Feathers are a ______________________________character because they evolved in
one group but not the other.
23. Look at Fig 7, p. 310. Compare and contrast these two representations.
