Mystery Fossil Project Specifications Anthropology 021 uses the Mystery Fossil CR-ROM to expose the student to laboratory exercises in biological anthropology. Students must complete this exercise in groups of four. In special cases there may be groups of three, but it is most advantageous to work with four people. This project is due on Thursday August 6, 2009. Semester Timeline and Project Details Group Assigning: At the end of class on Tuesday July 14, 2009, you will divide yourselves into groups. Each group will consist of four individuals. All groups must hand in a paper (handwritten is fine) that indicates: a) each group member’s name, and b) a group name (have fun and be creative!). Groups will submit this list in person to the instructor. Individuals present on this day will receive 10 points. You must be present to receive the points. Students not present can still join a group, but will receive a zero for this portion Individual Exercises: Exercises 1 – 13 on the Mystery Fossil CD provide a virtual laboratory for the student to learn and use basic methods in biological anthropology to identify fossil species. Note: In groups of four, there will be one exercise that is not covered. In groups of three, there will be four exercises not covered. The group must divide these exercises up among the individual group members. Each member will be responsible for completing 3 exercises (no more, no less). Each student is now responsible for completing these exercises. The group will not be penalized if any individual member fails to complete their assigned exercises. Each of these exercises must be printed in their entirety (not necessary to print in color). This includes all charts, graphs, and response questions. Please write your name on each of your exercises. You will lose 20% on each individual exercise on which you fail to write your name. Only one group member may choose two exercises from exercise 6 – 11. This group member will also be responsible for exercise 5. All other group members must be assigned only one exercise from 6 – 11. The group must submit a list of each member and which exercises they will be responsible for completing. This list is worth 10 points for each group member, and is due on Thursday July 16, 2009. Group Exercise: The group will complete exercise 14 together. Work on this together - DO NOT DIVIDE THIS UP AND WORK SEPARATELY. This exercise is to be submitted with the final project, which is detailed below. Final Project: Each group must submit all completed exercises together by the due date on Thursday August 6, 2009. Please submit these in a PLAIN MANILLA folder or envelope. The final project must include a cover page that indicates the group name, the names of each group member, and the date of submission. Keep the cover page simple. Please no graphics, bold print, or super-sized font. Times New Roman in 12 point font is desirable. Groups that do not submit a cover page will lose 20% from their exercise 14 grade. It is the group’s decision whom to include on the cover sheet. If a member of the group did not contribute to exercise 14, do not include their name on the cover sheet. Only people whose names that appear on the cover sheet will be given a grade for exercise 14. People whose names do not appear will be given a 0 out of 50. Individual exercises will each be graded out of a possible 10 points. Grading emphasizes both completeness and accuracy. The group exercise will be graded out of a possible 50 points. Exercise 14 is quite a detailed assignment. The instructions for this exercise on the actual CD can be quite confusing, so I recommend using my instructions contained in this document. Be sure to follow each step that I outline, and please submit all your work. Grading: Individual points – Group Assignment Day – 7/14/09 (10 points) Individual Exercises – 8/6/09 (10 points each/30 total) Group points – Individual Exercises List – 7/16/09 (10 points) + Exercise 14 – 8/6/09 (50 points) = Overall project grade (100 possible points) Exercise Descriptions Exercise 1 – Basic skeletal and dental anatomy This exercise requires that you identify specific bones based on the exercise descriptions. Use the “Anatomy” and “Glossary” sections in addition to your textbook to assist you. Hand in the PDF answer sheet. Exercise 2 – Dating methods This exercise requires you to analyze 5 different dating methods. Use What you need to identify: How far back in time each method is useful (this includes both years and epochs)? Is the technique is relative or absolute? Then, you will need to go through EVERY fossil on the CD and identify which fossils were dated with each method. You will find this information in each fossil description. Hand in the PDF answer sheet (including both chart and essay) and the two dating methods graphs. Exercise 3 – Distinguishing Hominins In this exercise, you will compare the cranial and dental features of humans, chimpanzees and Australopithecus afarensis. Pictures of all three can be found on the CD. For each you will need to describe the specific feature (if you do not know the feature, use the CD glossary or your book to define the term). Descriptions need not be complex. Keep them short and based on your personal observations. You will then use this information to answer 3 questions. You will hand in the PDF answer sheet that includes the feature chart and 3 questions. Exercise 4 – Evolutionary trends in cranial capacity This exercise requires you to use the cranial capacity data and age of each fossil to discern trends in our evolutionary history. Fill in the table for each fossil with both the cranial capacity (CC) and age (in MYR – million years). Note: Some fossils will not be more than one million years old. In this case you will need to enter a decimal – 200,000 years = .2 million years. If the species is currently living (humans or chimps) enter 0. Once all data is entered, you will produce a graph that will enable you to answer the 3 questions. Please be specific in your answers. You will hand in the PDF answer sheet and the graph. Exercise 5 – Evolution of the Hominin face and skull For this exercise, you will need to use the CD’s measuring feature to measure specific features of each skull. Measure each as describe by the exercise and enter the data in the corresponding table (there are 5 different tables). Since you cannot save this data on a hard drive, you will want to backup your data on a sheet of paper or in an Excel document. Once all data is entered, you will produce 3 graphs. You will then use this information to answer 6 questions. Please be specific in your answers. You will hand in the PDF answer sheet, the 5 tables, and the 3 graphs. Exercises 6 – 11 – Identifying the Mystery Fossils This set of exercises requires you to use some of the skills highlighted in the first five exercises to identify the genus and species of each mystery fossil. Be forewarned that this identification process is not an easy on by any means, and will require you to provide several pieces of evidence to support your argument. The goal here is to display a basic understanding of the process of identifying genus and species when presented with only fossil remains. To begin, identify what genus and species (ex. – Homo sapiens) to which you assign the fossil. Note: The archaeological site name is not the genus and species. For example, Herto is a site name. Homo sapiens is the species found at the Herto site Be sure to compare the mystery fossil data found on the CD to data for the species found in Essentials of Physical Anthropology. Some areas to focus in on are: Dating – What is the date of your mystery fossil? How was the date established? What is the range of dates in which the species (not the mystery fossil) lived, according to Essentials of Physical Anthropology? Does the date of your mystery fossil fit within this range? Geographic area – Was your mystery fossil found in a geographic area where the species has been know to have lived? Morphological features – Does your mystery fossil share cranial, dental or post-cranial features with the species? What specific features do they share? Please describe the similarities The important thing for this exercise is to be as specific as possible. Be sure to point out how the data for the mystery fossil corresponds to the data for the species. You will want to provide a well informed, convincing argument that could be understood by someone without a degree in biological anthropology. This means that you will want to put your description in language that you can understand. Avoid using terms that you do not understand. Any time you use terminology, please bold the term and provide a clear definition. Failure to do so will result in a loss of points. Type your answer in Microsoft Word. At the top of the document, please indicate your name and the exercise number. Your answer must be double spaced in 12-point Times New Roman font. Answers must be at least one full page and cannot exceed two full pages. Please cite all sources within the body of your answer. You will hand in a printed copy of this document. Exercise 12 – Lumping and Splitting Are you a lumper or a splitter? This exercise requires you to fill out a table will data from 5 fossils that can be found on the CD. You will then use the table to the 3 questions. Please be specific in your answers. You will hand in the PDF answer sheet including both the table and the questions. Exercise 13 – The Paranthropus question In this exercise, you will decide whether or not to create a new genus – Paranthropus. Use the data from the CD to answer the questions. Please be specific in your answers You will hand in the PDF answer sheet. Exercise 14 – Creating a phylogeny This exercise asks you to produce a phylogeny (family tree) for all of the fossils found on the CD. Before you begin, take some time to review the given phylogenies found on the CD. This will help you by provide a model for your work. Before you begin, you will need to purchase a silver marker. You will need this to write on your charts, as they will print out with a black background. You can find these at any office supply store or Walmart. This exercise is an extensive and detailed assignment that will require contributions from all members. You will be most successful working together as a group. By all means, DO NOT divide up this exercise and work separately. Working separately ensures that your final product will have no coherency, and is certain to receive a poor grade. The instructions found on the CD are quite confusing. Instead of driving yourselves nuts trying to decode what is being asked of you, follow these simple steps: Step One Arrange all of the fossils on the basis of time. Your time scale will go from left to right, starting at 4 million years and ending at the present. You do not need to consider any relationships between the species in portion of the exercise. Simply arrange on the basis of time. o Use the data on the CD for each fossil to find the date. When you are finished, print this chart. Along the bottom line, use your silver pen to label the tick marks for 4, 3, 2, 1 and 0 (for the present). Use your silver pen to label each fossil by number (1 – 24). o In Microsoft Word, list these fossils and their corresponding number. o Print this document. Using black ink, label this printout at the top as “Step One.” Step Two Take your chart from Step One and do not change where fossils are located from left to right. They will stay in the same time period. Go to each time period and being clustering fossils on the basis of similarities. One of the fossils was a fake and should be set off by its self. Do you know which one? One of the fossils is also not a hominid. This fossil should also be set off from the rest. After you have finished clustering, print this chart. o Again, label the tick marks with your silver pen (4, 3, 2, 1, and 0). o Also, use your silver pen to again label each fossil by number (1 – 24). This should correspond to the list you printed out for Step One. On the chart printout, use your silver pen to circle each of the clustered groups. o You will determine how many based on whether your group lumps or splits (see question 4 below). o From left to right, label each circled grouping a letter designation (a, b, c, d, etc.). Using black ink, label this printout at the top as “Step Two.” Step Three Print out another copy of your Step Two chart. o Again use your silver pen to circle and label your groupings, and to label the tick marks (4, 3, 2, 1, 0). o Also, use your silver pen to again label each fossil by number (1 – 26). This should correspond to the list you printed out for Step One. o At this point, your chart should be identical to the Step Two chart. Take this chart and use your silver pen to draw lines that connect your groupings. o These lines indicate evolutionary relationships. Carefully think out these connections. o Do not connect groupings that you do not believe to be related. o Remember: Hominid evolution did not occur in a straight line. So your phylogeny should not be one! Using black ink, label this printout at the top as “Step Three.” Congratulations! You have just produced a phylogeny. You will now need to use your phylogeny (the Step Three printout) to answer 4 questions. Please answer these questions in Microsoft Word using double spacing and 12-point Times New Roman font. Question 1 Assign a genus and species to each grouping (a, b, c, d, etc.). Write the number of each fossil (from your Step One list) in the group. Be sure that all members of the group can be placed within that genus and species. This should be in list form. Question 2 Identify the key distinguishing features (cranial, dental, temporal, geographical) for each group. This should be in list form. Question 3 Compare your phylogeny to the sample phylogenies found on the CD. Which sample phylogeny is yours most like and why? Be specific! o To answer this question, describe the sample phylogeny. Then describe how your phylogeny mirrors the key features of the sample. Question 4 Describe the terms “lumping” and “splitting.” You can find definitions in Essentials of Physical Anthropology. Refer back to your Step Two chart when you established your groupings, and to your answer to Question 1. o Did you lump or split? o Why did you approach the assignment this way? o Again, be as specific as possible in describing your groupings. You will hand printouts of the Step One chart, the Step Two chart, the Step Three Chart, the document containing the numbered species, and the document containing your answers the four Questions.
