ABFM ABFM Forensic Anthropology & Identification 1 — Questions and Answers
Question 1: Which skeletal region is considered the most reliable for determining biological sex in forensic anthropology?
- Femur length
- Long bone cortical thickness
- Pelvis morphology (Correct answer)
- Skull suture pattern
Correct answer: Pelvis morphology
The pelvis, particularly the subpubic angle and sciatic notch, shows the greatest sexual dimorphism and is most reliable for sex determination.
Question 2: What skeletal indicator is primarily used to estimate biological age in skeletonized juvenile remains?
- Cranial suture closure
- Epiphyseal fusion and dental eruption (Correct answer)
- Femoral head diameter
- Pubic symphysis morphology
Correct answer: Epiphyseal fusion and dental eruption
Epiphyseal fusion patterns and dental eruption sequences provide reliable age estimates in subadult skeletal remains.
Question 3: Stature estimation from skeletal remains is most accurately determined using which bones?
- Carpals and tarsals
- Clavicle and scapula
- Long bones of the limbs (femur, tibia) (Correct answer)
- Vertebral column segment lengths
Correct answer: Long bones of the limbs (femur, tibia)
Long bones, especially the femur and tibia, have the strongest correlation with living stature through established regression formulae.
Question 4: In forensic anthropology, what does 'the biological profile' include?
- Cause and manner of death
- DNA genotype and blood group
- Sex, age, stature, and ancestry estimates (Correct answer)
- Time of death and decomposition stage
Correct answer: Sex, age, stature, and ancestry estimates
The biological profile is a skeletal assessment encompassing estimated biological sex, age at death, stature, and ancestry to narrow identification.
Question 5: Which dental feature is most useful for estimating age in adult skeletal remains when epiphyses are fused?
- Crown morphology
- Dental caries location
- Root resorption and wear patterns (Correct answer)
- Tooth enamel color
Correct answer: Root resorption and wear patterns
In adults, dental root resorption, attrition (wear), and cementum annulation correlate with advancing age and are used for age estimation.
Question 6: Forensic anthropologists use population-specific regression equations when estimating stature because?
- Body proportions vary significantly among ancestral groups (Correct answer)
- Crime labs require standardized regional data
- Long bone measurements differ by climate only
- Stature decreases with age uniformly across all groups
Correct answer: Body proportions vary significantly among ancestral groups
Limb-to-stature proportions differ across ancestral populations, so population-specific formulae improve stature estimation accuracy.
