ANTHROPOLOGY REVIEW 1. What Is the Primary Job of a Forensic Anthropologist? to Determine the Identity of Skeletal Remains in Criminal Cases Name : ___________________________________ ANTHROPOLOGY REVIEW 1. What is the primary job of a forensic anthropologist? To determine the identity of skeletal remains in criminal cases. 2. Why is it difficult to determine sex in young children? The skeleton doesn’t differentiate by sex until after puberty. (little boy skeletons and little girl skeletons are identical) 3. What three bones can be used to determine sex in adults? Which is best? Pelvis, skull, femur. Pelvis is best 4. Mark the following as Male or Female characteristics: a. large brow ridge Male b. short, wide sacrum Female c. flexible, small coccyx Female d. subpubic angle of 105 degree Female e. subpubic angle of 87 degree Male f. pelvis is wider and flared Female g. opening in pelvis is heart-shaped Male h. bones in pelvis are thinner Female i. occipital protuberance is absent Female j. large mastoid process Male k. jaw angle is 102 degrees Female l. ocular orbits are round Female m. skull is generally smaller Female n. forehead is low and sloping Male o. skull is bumpy and rough Male p. femur meets pelvis at very sharp angle Female q. bones are denser and bumpier Male BE ABLE TO WORK PROBLEMS LIKE THOSE ON RM 99-100. BE ABLE TO LOOK AT PICTURES AND TELL MALE/FEMALE. 5. What is the best indicator of age in children? teeth 6. Describe the different ways to assess age of an adult. Pelvic wear and tear, skull sutures, rib endings, osteon size in bones 7. Be able to work problems using the pattern of tooth eruption to estimate age. Study the diagrams on 107-108. A. the skeleton of a young child was found with no teeth erupted; estimate age. Less than 10 months B. the skeleton of a child was discovered with all primary teeth present and no erupted adult teeth; estimate age. 25 months to 6 years 8. Be able to work age problems based on skull sutures, etc. Like those problems on RM 99 9. Estimate age if: a. Lambdoidal sutures almost fused. Age__________ almost 30 (26-30) Sagittal and coronal sutures not fused. b. Lambdoidal sutures not fused. Age__ less than 30 (if lambdoidal is wide open = less than 21) Sagittal and coronal sutures not fused. c. All sutures are wide open Age _________ less than 21 d. All sutures are closed Age _________ fifty plus 10. What is the best indicator of race? The skull (particularly nasal index) 11. Explain how experts can assess age by looking at bone fragments under a microscope. More small osteons = older; Less but larger osteons = male 12. How can experts determine handedness from assessing a skeleton? Dominant bones will grow larger 13. Be able to answer questions about anthropological values and their relationships to each other such as height and arm span or height and stride length. (RM pages 109-112) both are related; arm span and height are frequently the same or very close 14. What is the last bone to stop growing? clavicle 15. What is an indication that a woman has given birth? Scarring on the pubic bones (called parturition pits) 16. Be able to determine height if given bone length. Be able to determine bone length if given height. RM 103-106 a. Caucasian female; femur is 50 cm 173.88-181.32 b. African American female; humerus is 31cm 155.9-164.4 c. Male; unknown race; tibia is 35 cm 158.34-166.64 I will provide the equations for height using various bones. Scenarios: 17. A skeleton was found with large muscle attachments and a subpubic angle of 88 degrees. The skull showed no evidence of sutures closing and wisdom teeth had not erupted from the gums. Tibia length is 37cm. What can you determine about this individual? Male, less than 21 years of age, approximately 169 cm in height 18. A skull was found with a jaw angle of 103 degrees and no occipital protuberance. All skull sutures have closed. What can you determine about this individual? Female, older than 50 19. A body is found with the lambdoidal suture closed but sagittal and coronal sutures open. The pelvis shows parturition pits. Body does not exhibit rigor but lividity is fixed. Bruising on neck and petechial hemorrhage is evident. Femur length is 41 cm. What can you determine about this individual? Female that has given birth, between the ages of 30-32, dead more than 36 hours, COD is likely strangulation, height is approximately 157 cm .

Evolution serves as a foundation to many biological concepts by tying together the different tenants of biology, like ecology, anatomy, genetics, zoology, and taxonomy. It is for this reason that evolution plays a prominent role in the state and national standards and deserves thorough coverage in a classroom. A prime example of evolution can be seen in our own ancestral history, and this unit provides students with an excellent opportunity to consider the multiple lines of evidence that support hominid evolution. By allowing students the chance to uncover the supporting evidence for evolution themselves, they discover the ways the theory of evolution is supported by multiple sources. It is our hope that the opportunity to handle our ancestors’ bone casts and examine real molecular data, in an inquiry based environment, will pique the interest of students, ultimately leading them to conclude that the evidence they have gathered thoroughly supports the theory of evolution.

  • Is the Skeleton Male Or Female? the Pelvis Tells the Story
    Activity: Is the Skeleton Male or Female? The pelvis tells the story. Distinct features adapted for childbearing distinguish adult females from males. Other bones and the skull also have features that can indicate sex, though less reliably. In young children, these sex-related features are less obvious and more difficult to interpret. Subtle sex differences are detectable in younger skeletons, but they become more defined following puberty and sexual maturation. What are the differences? Compare the two illustrations below in Figure 1. Female Pelvic Bones Male Pelvic Bones Broader sciatic notch Narrower sciatic notch Raised auricular surface Flat auricular surface Figure 1. Female and male pelvic bones. (Source: Smithsonian Institution, illustrated by Diana Marques) Figure 2. Pelvic bone of the skeleton in the cellar. (Source: Smithsonian Institution) Skull (Cranium and Mandible) Male Skulls Generally larger than female Larger projections behind the Larger brow ridges, with sloping, ears (mastoid processes) less rounded forehead Square chin with a more vertical Greater definition of muscle (acute) angle of the jaw attachment areas on the back of the head Figure 3. Male skulls. (Source: Smithsonian Institution, illustrated by Diana Marques) Female Skulls Smoother bone surfaces where Smaller projections behind the muscles attach ears (mastoid processes) Less pronounced brow ridges, Chin more pointed, with a larger, with more vertical forehead obtuse angle of the jaw Sharp upper margins of the eye orbits Figure 4. Female skulls. (Source: Smithsonian Institution, illustrated by Diana Marques) What Do You Think? Comparing the skull from the cellar in Figure 5 (below) with the illustrated male and female skulls in Figures 3 and 4, write Male or Female to note the sex depicted by each feature.

  • AP Skull Measurement Guide, Laminate
    Skull Measurement Guide L – Length of the brain case: Position three rulers as shown in photograph 1 below. Ruler 1 should stand perpendicular to the table, and rest at the back of the skull. Ruler 2 should also stand perpendicular to the table, but rest on top of the skull, just behind the brow ridge. If a brow ridge is not present, align the ruler against the forehead in the same perpendicular orientation (imagine it flat against your forehead). Ruler 3 should rest on the highest point of the cranium, making sure that it is parallel with the table. Once all 3 rulers are in place, read the distance on Ruler 3 between the 2 upright rulers in mm (see photograph 2 below). Record your data in the first column labeled “L”. Skull length measurements for two different species: View from the side (left), view from the top (right). H – Height of the brain case: Without moving the 3 rulers from your measurement of Length, read the height of the skull off Ruler 1 (at the back of the skull) in mm (also see photographs below). Record your data in the first column labeled “H”. Skull height measurement: view from the side for two different species – note: upright ruler in the front of skull is removed.

  • Eyebrow Peak Position Redefined © 2010 the American Society for Aesthetic Plastic Surgery, Inc
    Facial Surgery Aesthetic Surgery Journal 30(3) 297 –300 Eyebrow Peak Position Redefined © 2010 The American Society for Aesthetic Plastic Surgery, Inc. Reprints and permission: http://www .sagepub.com/ journalsPermissions.nav DOI: 10.1177/1090820X10369918 Sylvia Pham; Bradon Wilhelmi, MD; and Arian Mowlavi, MD www.aestheticsurgeryjournal.com Abstract Background: The aesthetically appealing eyebrow shape has been defined by its arch, located near the junction between the medial two-thirds and lateral one-third. The position of this arch has been historically described by arbitrary anatomical landmarks that have no logical structural relationship. Moreover, selection of endoscopic brow lift incision sites that define vector of pull and fixation points have been variably described. Objectives: The authors examine the position of the deep temporal fusion line to determine whether it can act as a more accurate and functional landmark than prior anatomical landmarks for the eyebrow peak position. Methods: Eyebrows were measured in 50 subjects from the medial aspect of the eyebrow to the a) deep temporal fusion line (ridge), b) eyebrow peak (arch), c) lateral aspect of the brow, and d) lateral limbus. Pearson's correlation, descriptive statistics, and student's t test results were obtained. Results: Eyebrow measurements demonstrated that the deep temporal fusion line is the most precise indicator of brow peak position among all examined landmarks. The Pearson correlation value was strongest between brow peak and deep temporal fusion line (P = .860) and a t test confirmed this observation with no significant difference between brow peak and deep temporal fusion line. The lateral limbus and medial two-thirds lateral one- third junction more accurately predict brow peak in females, but the deep temporal fusion line is an equally reliable predictor of brow peak for males and females.

  • Skull Anatomy
    Skull Anatomy Cranial Capacity (braincase size) – cranium minus the face; may or may not indicate the level of intelligence (Intelligence is determined by overall size of the organism, where it lives, and the level of brain development.) Post-orbital Construction – the narrowing of the braincase behind the eye orbits; the orbit is the eye socket Sagittal Crest – ridge on top of the cranium for attachment of chewing muscles; runs down the middle of the top of the head; seen in predators that chase and bring down prey Forehead – frontal bone (A vertical forehead indicates an expanded frontal lobe, which is used for planning, reasoning, judgement, future consequences from current actions.) Foramen Magnum – the opening in the base of the skull where the spinal cord enters (The location indicates whether an organism is bipedal or quadruped.) Brow Ridge – bony ridge over the eye orbit (This reinforces weaker bones of the face due to strong chewing muscles.) Facial Prognathism – forward projection of the jaws and teeth beyond the cheek bone (A less forward projection indicates a reduction in tooth size due to a change in diet and cooked food. Chin angle relates to this.) Chin – slopes backward without a point or forward with a pointed end Dental Arcade – shape of the teeth row when viewed from above (U-shaped or parabolic- shaped) Teeth – Incisors – for cutting Canines – for tearing Molars – for grinding Canine Diastema – gap between the upper incisors and canines, and lower canines and premolars (the diastema is either present or absent to accommodate the canine from the opposite jaw) .

  • Patterns of Morphological Integration in Modern Human Crania: Evaluating Hypotheses of Modularity Using Geometric Morphometrics
    PATTERNS OF MORPHOLOGICAL INTEGRATION IN MODERN HUMAN CRANIA: EVALUATING HYPOTHESES OF MODULARITY USING GEOMETRIC MORPHOMETRICS DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Adam Kolatorowicz Graduate Program in Anthropology The Ohio State University 2015 Dissertation Committee: Jeffrey K. McKee, Advisor Paul W. Sciulli Samuel D. Stout Mark Hubbe Copyrighted by Adam Kolatorowicz 2015 ABSTRACT This project examines patterns of phenotypic integration in modern human cranial morphology using geometric morphometric methods. It is theoretically based in the functional paradigm of craniofacial growth and morphological integration. The hypotheses being addressed are: 1) cranial form is influenced by secular trends, sex, and phylogenetic history of the population and 2) integration patterns wherein the basicranium is the keystone feature best explains the relationships among in cranial modules. Geometric morphometric methods were used to collect and analyze three- dimensional coordinate data of 152 endocranial and ectocranial landmarks from 391 anatomically modern human crania. These crania are derived from temporally historic and recent groups in the United States spanning both sexes and across several ancestral groups. Landmark data were subjected to generalized Procrustes analysis and then areas of shape variation were identified via principal components analysis of shape coordinates. Discriminant function analysis and canonical variate analysis identified regions that can be used to separate groups. Temporal period, ancestry, and sex all have significant effects on mean shape. Age-at-death accounts for a small proportion of the total variation. Modern individuals have higher, narrower vaults with highly arched palates ii and historic individuals have short, wider vaults with shallower palates.
