Paleoenvironments and Human Evolution
Professor Jeanne Sept
Spring Semester 2001: intensive 8-week course
Tuesday-Thursday 4:00-6:15, Student Building 0150
The goal of this course is to give you an understanding of how paleo-anthropologists can investigate the environmental context of the fossil and archaeological records of proto-humans. We have three basic objectives:
1) to understand the methods of paleo-environmental reconstruction
2) to evaluate site-specific examples of paleo-habitats and hominid paleo-ecology
3) to pursue the larger-scale evolutionary questions of how the human past was shaped by patterns of environmental change.
Since this is an "eight-week" course for 3 credits, the work-load will seem intensive, because we will be covering material at twice the rate of a normal, semester-long course. Just be prepared to plunge-in I hope it will be both interesting and fun!
First class meets Tuesday March 6, 2001 . Last class meets Thursday April 26 2001
Final papers due by 5:00 on Tuesday May 1 (day of final exam)
Basic course organization:
We will be reading and discussing primary literature from scientific journals and edited volumes. Readings will be on reserve in the Geography Library.
- For the first half of the course we will review the most important methods of paleo-environmental reconstruction. In general, everybody will read the same methods papers, and different students will take turns presenting case studies that illustrate how the methods have been applied.
- Mid-way through the class we will hold a "symposium" in which every student will play the role of a specialist who has analyzed a different type of data from the same site. The goal of the symposium will be to work out the best interpretation of hominid ecology at the site.
- The last half of the class we will read and discuss the current hypotheses about the impact of global environmental change on human evolution, and students will be focusing on and giving brief reports on their own research papers.
Course office hours: Ill be available right after class (TR 6:15-7:00) for short questions, or you can schedule a longer appointment with me at another time.
The best part of a seminar is listening to other students reactions to the readings and issues, and developing your own sense of the material through discussion with others. Therefore, your grades will be based on both written work, and class participation. Graduate students enrolled in P600 will be expected to write more thorough reading responses and research papers than the undergraduates.
Class meetings = 25% of grade:
- 1 pt for each attendance/in-class discussion or participation (14 pts total), and
- 1 pt for each reading assignment response (11 pts)
(if you miss a class meeting, you can make up credit by writing a response to an extra assignment question)
Symposium mid-term project: 25% of grade
- A short specialist report to present to students at symposium (10% of grade)
An essay synthesizing results of the class symposium (15% of grade)
Final research paper: 50% of grade (~15 pages for undergrads)
Many options will be available for research paper topics. For example:
- You could focus on comparing how two closely-related methods of paleoenvironmental reconstruction (e.g. vegetation reconstruction based on pollen analysis versus soil chemistry) have been applied at different sites
- You could evaluate controversies concerning the paleoenvironmental reconstruction for a single site (e.g. the Miocene ape site of Ft. Ternan)
- You could summarize the historical development of a method
- You could focus on a broad question of hominid evolution, such as the "savanna hypothesis" for the emergence of bipedalism and evaluate the data available to test it
- You could evaluate attempts to reconstruct the habitat of different contemporary species of hominids (e.g., boisei vs habilis)
- You could look at archaeological evidence of how hominid exploitation of a particular type of habitat changed through time in one region
- You could summarize the evidence for the total variety of different habitat types known to have been occupied by a hominid species at a particular moment in time
While many examples we will discuss in class will come from the Plio-Pleistocene of Africa, you are welcome to do a research paper on some human evolution / paleo-environmental question from any region and time you want to. . You just need to discuss it and get your topic approved by Professor Sept before you do it.

Marine records of climate and hominoid evolution
Read the following chapters and article with the goal of understanding how climate change has influenced the oceans and the proxy indicators of climatic change that are preserved in the marine records. Be able to explain the principles behind Oxygen isotope analysis and explain what Oxygen Isotope stages are. Why are marine sediment cores more informative than ice cores for reconstructing the climatic context of human evolution?

Thursday April 5 (revised)
Can the habitat of the early east African hominid speceis be resolved from fossil associations? Everyone read this general article, not worrying about the details of specific sites, but focusing on the "take home message" of method and theory:
- T.D. White 1988
"The comparative biology of "robust" australopithecus: clues from context" in Evolutionary History of the Robust Australopithecines (F. Grine, ed), pp 449-483.
Each of the following articles is a short research report in Nature. that includes a brief description of preliminary evidence for an early australopithecine habitat. Compare TWO of them.
- M.G. Leakey, et al 1995
"New four-million-year-old hominid species from Kanapoi and Allia Bay, Kenya" Nature 376: 565-571
- M. Brunet et al 1995

- M.G. Leakey et al 2001

For each of these articles, compare the evidence described for paleoenvironment with the hypotheses suggested for hominid habitat. Think about what questions you would like to ask the authors to evaluate the strength of their interpretations. Also, if you were going to design the next phase of one of these research projects to collect more data about habitat, what should they do next?
