Report
ANT 201, Fall 2019, Lab13: Pleistocene Evolution Dr. Benjamin Z. Freed, Eastern Kentucky University Dept. Anthropology, Sociology, & Social Work PURPOSE: to introduce comparative cranial-dental anatomy among Pleistocene hominins. LAB OUTCOMES: The successful student will correctly be able to: 1) Compare major cranial-dental features to understand the classification of fossil hominins. 2) Identify & describe the taxonomy of Pleistocene hominins. 3) Recognize when specific human traits first appear in the fossil record. 4) Identify difficulties with how we define modern humans. 5) Recognize and differentiate significant paleontological events in the Pleistocene. 6) Identify and explain each of the following organisms and their significance in Pleistocene evolution: Homo erectus/ergaster, Homo antecessor, Homo heidelbergensis, Homo neanderthalensis , and Homo sapiens . 7) Define and describe what factors led to the speciation, spread, and, in some cases, extinction of the above fossil hominins. 8) Recognize and explain the significance of dental, cranial, and postcranial evidence about each of the above fossil humans. DUE DATE: Wednesday-Monday, 11/20-25/19 DIRECTIONS/TIMETABLE: The lab has several sections: Before coming to class, do PreQ13 (5 pts) and review Modules19-21. Complete the in-class activity on Day 1. (12 pts) Complete the video on Day 2. (14 pts) Do the Individual Quiz on Day 2. (14 pts) POINTS: 45 points + (5 Extra Credit Points) Part Points Online Before Day 1 PreQ13 5 Self Day 1 Part 1 Cladogram Exercise 12 Self Day 1 Extra Credit Booster (5) Self Day 2 Parts 2 a & b Video: Becoming Human 2 & 3 8+6 Self Day 2 Part 3 Individual Quiz 14 Self
NOTES: While you look at 6 different species, you will want to examine the traits you see on the cladogram matrix, and you will want to look at the following: 1. Mandibular horizontal ramus: robusticity, chin, buttressing/extra support surrounding teeth, shape of the dental arcade (block U, U, parabola), retromolar space 2. Maxilla: prognathism, mid-face projection, robusticity, flaring to the side 3. Teeth: size/shape issues with the incisors, canines, premolars, & molars; poscanine megadontia 4. Zygomatic: flare, depth/height 5. Frontal: forehead, supraorbital torus (shape, size, length), postorbital constriction 6. Parietals: size, curvature, sagittal crest, sagittal keel 7. Temporal: mastoid process 8. Occipital: foramen magnum, curvature vs. squared-off/angled bottom, nuchal crest, protuberance, torus, bun 9. Skull shape: height of maximum breadth; cranial capacity, elongation, eggplant shape.
NAME: _____________________Lab13: Part 2b: Becoming Human Part 3: 6 pts 1. Describe two significant aspects of the human ( Homo heidelbergensis ) and material remains of Atapuerca. 2. What do the remains at Scladina suggest about growth and development in Neanderthals? 3. Describe the diet of the human population of Pinnacle Point. When did humans live there? What do their diet and their material remains suggest about their thought processes?
