Use the assigned textbook Forensic Anthropology
Use the assigned textbook Forensic Anthropology: Current Methods and Practice (Christensen, 2019) Chapter 8, in addition to the sex estimation lab supplemental readings (see Blackboard) to answer each question.
- Sex differences in the human skeleton are primarily related to what 2 features? What are these features a result from?
- Explain the difference between biological sex and gender.
- Describe any 1 feature on a bone that can be used for sex estimation. Where is it and at what point does it indicate male or female?
- Refer to the supplemental readings and briefly discuss 1 of the sex estimation metric methods.
- After observing the pelvic morphology of an unknown individual, you give the specimen a score of “2” for the greater sciatic notch and a “3” for the preauricular sulcus. Additionally, you note the presence of the ventral arc, the significant concave appearance for the subpubic concavity, and an ischiopubic ramus that is somewhat narrow with a ridge on the medial aspect. What is the estimated sex of this individual? (Standards; Buikstra and Ubelaker, 1995; “Os Coxae Morphology”)
- Using only the cranium, you attempt to estimate the sex of an individual. You scored the nuchal crest a “1”, the mastoid process a “1”, the supra-orbital margin a “2”, the glabella a “2”, and the mental eminence a “3”. Based on these scores you can estimate that the sex of this individual is:
(Standards; Buikstra and Ubelaker, 1995)
- Use the femoral neck diameter provided and apply it to the discriminant function equation (unknown ancestry) from Seidemann, 1998 to determine the sex of the individual:
|Side:||Femoral Neck Diameter:||Sex:|
- Using the indicated supplemental reading, choose the sex of a hypothetical individual. Then assign scores to the sex-related features of the os coxa that correspond with the appropriate sex: (Standards; Buikstra and Ubelaker, 1995).
|Os coxa #18||Side: Right|
|Ventral arc (1-3)|
|Subpubic concavity (1-3)|
|Ishiopubic ramus (1-3)|
|Greater sciatic notch (1-5)|
|Preauricular sulcus (0-4)|
- In 2-3 sentences, explain what sexual dimorphism is and provide an example.
- The _________________ is the most sexually dimorphic region of the human skeleton.
