List for first review -- due Sept. 23, 2020
List for second review -- due Oct. 12, 2020
List for third review -- due Nov. 2, 2020
Don't forget: for the second and third reviews you can use articles from the previous lists, so, in the end, if you wish to review
three articles form the first list, that would be fine. Do be aware that some articles are shorter than others, so you should look around before you choose.

Zonosemata vittigera and Phidippus apacheanus -- a picture winged fly and a jumping spider predator
From: Green, E., L. J. Orsak, D. W. Whitman. 1987. A tephritid fly mimics the territorial displays of its jumping spider predators. Science, New Series, 236(4799): 310-312.

Coevolution: Orchids and orchid bees
These are three species of Callosamia, all found in Georgia. Males are the top row, females are the bottom
row. On the left is Callosamia securifera; in the middle is Callosamia promethea, and on the right is Callosamia
angulifera. There are many places in the state where at least two of them can be found (both promethea and
angulifera are widespread) and may even be places where all three could be found. The females all use the
same pheromone for attracting the males. How to they stay separate? They mate at different times of the day.
C. securifera mates around noon; C. promethea mates in the late afternoon; and C. angulifera mates only after
dark. So, even though the females could theoretically attract males of the other species, they are kept separate
by different mating times.

DESCRIPTION OF THE COURSE: This course
introduces you to the basic fundamentals of the
concept of evolution. You will learn about the overwhelming evidence (both past and current) for
evolution, as well as the method by which evolution proceeds – mutation, followed by natural selection.
We will investigate the major mechanisms by which natural selection results in change, and how in turn
this results in organismal adaptations. We will then, in turn discuss how different adaptations in different
populations may result in new species – speciation – and how this explains the history of life on earth.
If time, we will end with a brief look at current research, particularly at the molecular level, as it applies
COURSE OBJECTIVES: Upon completion of this course, you should be able to:
1. Define and use the concept of evolution in discussing relationships of
2. Describe the basic premises and process of natural selection, indicating why it is that it virtually
must be true that organisms change through time.
3. Demonstrate an understanding of the main processes involved in evolution:
mutation, selection (including sexual, kin, etc.), migration, drift
4. Demonstrate an understanding of the major possible mechanisms involved in speciation.
5. Describe why all organisms are related, and indicate what it means from an evolutionary
perspective to say organisms are closely related.
6. Understand how to construct phylogenies (i.e., evolutionary trees of relationships).
