Study Notes
Forensic Anthropology Overview
- Forensic anthropology is the study of human remains to solve criminal cases.
- Osteology is the study of bones and the human skeleton, a crucial aspect of forensic anthropology.
- Anthropologists analyze skeletal remains to determine characteristics, aiding in identifying individuals, especially before DNA matches are possible.
- Forensic anthropologists assist in investigations, including war crimes, genocides, mass graves, plane crashes, and other criminal cases.
History of Forensic Anthropology
- Thomas Todd, in 1912, assembled the first large collection of human skeletons, contributing to aging skeleton studies.
- Wilton Krogman, in 1939, published a guide to identifying human bones, standardizing methods in the field.
- He collaborated with the FBI, utilizing anthropological expertise for human remains identification, further applying this field in criminal justice.
- By the 1950s and 60s, forensic anthropology gained a more prominent professional status, establishing this field within the scientific community.
Case Study: USAir Flight 427
- On September 8, 1994, USAir Flight 427 crashed near Pittsburgh, resulting in the death of 132 passengers.
- The crash investigation revealed a faulty rudder as the cause of the crash.
- The crash site was extremely hazardous, with numerous body parts scattered, posing immense challenges for forensic identification.
- Forensic anthropologists painstakingly sorted through the remains to identify the deceased, working meticulously to overcome these obstacles.
- The plane crash resulted in an extensive biohazard situation with thousands of body parts to classify, complicating the identification process.
Human Skeleton
- Individuals are born with about 300 bones, which fuse together to form 206 bones in adults.
- The human skeleton is organized into the axial skeleton (spine, rib cage, skull) and the appendicular skeleton (shoulder girdle, arm and hand bones, pelvic girdle, leg and toes bones).
Human vs. Animal Bones
- A primary step in identifying human remains involves confirming human origin.
- Distinguishing features include:
- Presence of a chin
- Minimal nasal projection
- U-shaped mandible
- Large incisors, small canines
- Separate radius and ulna
- Long and narrow femur
- Long and narrow foot
Osteobiography
- Osteobiography is a person's life story, revealed through their bones.
- Bones reveal insight into a person's height, weight, gender, age, and health.
- Nutritional deficiencies, arthritis, and other health issues manifest in the bone structure and teeth.
- Dominant hand side can exhibit slightly longer bones.
- Specific wear and tear on joints can indicate past habitual activities, such as horseback riding.
Determining Gender
- The pelvis is the most reliable feature for determining skeletal gender.
- Females have wider, shallower pelvises for childbirth, while males typically have larger and more robust pelvics, with different muscle attachment patterns.
- Pelvic factors like subpubic angle and the shape of the pelvis differentiate male and female pelvics.
- Hormonal changes during pregnancy can leave visible scarring on the pelvic bone.
Specific Differences Between Male and Female Skeletons
- Male skulls tend to be larger, bumpier, with more pronounced brow ridges, and angular jawbones (90-degree angle).
- Female skulls are more vertical in the forehead, and the jawbone typically exhibits a more obtuse angle.
- Subpubic angle greater than 90 degrees usually indicates female (due to childbirth preparation).
- There is variability within and between these classifications due to the diversity of the human population.
Case Study: Babes in the Woods
- In Stanley Park, Vancouver, in 1953, the skeletons of two boys were discovered.
- Initially misidentified as a female, their identities were only confirmed through DNA testing in 1998, confirming they were brothers (Derek and David D'Alton).
Determining Height
- Height can be estimated using long bones like the femur, tibia, radius, and humerus.
- Specific formulas based on bone length and gender aid in more accurate estimations compared to earlier techniques.
- This can include identifying factors like ethnicity and gender to refine the estimates (potentially providing more precise estimations).
- Measurement accuracy allows for close estimation (within a particular margin of error).
Determining Age
- Age estimation involves evaluating certain bones and their maturity.
- More accurate estimations are achievable at younger ages.
- Characteristics including teeth, suture (fusion) marks on the skull, growth plates, and the pubic symphysis (bone) are utilized in the analysis..
- Factors affecting tooth eruption timing, such as diet and health, need to be considered in the age estimation equations.
Aging of Teeth
- Tooth eruption and fall-out timelines are used to aid in age estimation.
- Various teeth have specific eruption and fall-out dates, enhancing the timeline accuracy and precision, even with considerations of dental charts.
Aging of Suture Marks
- Infants are born with soft skulls that gradually fuse.
- Suture marks are the remnants of this fusion process on the skull, showing how the bones come together and fuse.
- Three prominent suture areas include the coronal, sagittal, and lambdoidal sutures, with characteristic timelines guiding age estimation.
Aging Due to Growth Plates
- Growth plates on long bones fuse at various stages of life, providing a timeline for age estimation (dependent on the stages of growth).
- Specific bone fusions (e.g., humerus, femur) occurring at different ages offer clearer timelines for age estimation. Factors, like nutrition and overall health state, affect timing.
Case Study: Romanovs
- In 1918, Tsar Nicholas II, his wife, and their five children were executed.
- Skeletal remains were buried in the forest for a considerable period, highlighting the challenges of identification.
- Their post-mortem burial in different locations further complicated the process.
- Skeletal remains were recovered and identified via anthropological techniques and DNA analysis in the 1990s, enhancing the ability to identify.
Race & Anthropology
- The determination of race from skeletal remains is less reliable due to movement and intermarriage of populations over different regions and timescales.
- Traditionally, anthropologists categorized people into three races (Caucasian, African, Asian) based on visual skeletal traits, but this is now questioned and reevaluated in modern scientific and medical practice.
- Current studies emphasize the diversity of human populations and how biological variations exist to different extents, and such variations may introduce inaccuracies in racial classification.
Determining Race
- Historically, anthropologists used skeletal features like nose shape, eye orbit shape, and mouth shape to approximate race.
- These methods are problematic as they don't account for variations within populations and fail to account for human diversity.
- Newer and more sophisticated methods for estimating biological ancestry are now in use.
Facial Reconstruction
- Facial reconstruction creates a likeness of a person based on their skeletal remains.
- Anthropologists use standard tissue depths to create a face from clay or other materials based on the skull features.
- Modern computer programs offer more customizable and realistic reconstructions, displaying greater accuracy than earlier methods, enhancing techniques for more realistic reconstructions.
- Facial reconstruction is a critical tool for forensic anthropology, especially for identification by family members and friends.
Case Study: Singer Island Jane Doe
- Skeletal remains were found in 1974 on Singer Island.
- The person appeared to have been tied to a tree, and had bullet wounds.
- Anthropologists, dental charts, and other resources were combined to approximate height, weight, and gender.
- In 2021, Jane Doe was identified as Susan Poole, a 15-year-old missing since 1972.
- The multifaceted investigation illustrates the importance of combining multiple forensic techniques to enhance accuracy and speed up identification.
Forensic Anthropologist Career Spotlight
- Forensic anthropologists identify human remains and determine cause of death.
- A detailed understanding of human anatomy, skeletal features, and identification metrics is necessary.
- Essential job duties include calculating height, age, gender, ethnicity, post-mortem interval, and cause of death (if possible).
- A Master's degree in Forensic Anthropology is typically required.
- Average salary is approximately $62,000 per year.
- Forensic anthropologists work in diverse settings, including crime labs, morgues, universities, and museums.
