Study Notes
Forensic Anthropology
- Forensic anthropology is the application of anthropological theory and methods to forensic problems.
- It's crucial when dealing with skeletal remains.
- Determining if skeletal remains are human and if they have forensic significance involves osteology (study of bones), odontology (study of teeth), and taphonomy (human form).
- Adult skeletons have 205 bones; children/infants have up to 405 due to differences in ossification.
- Post-mortem alterations need differentiation from pre-mortem changes.
- Forensic anthropologists frequently participate in body recovery and taphonomic context analysis.
- Analysis is helpful for understanding post-mortem processes.
Biological Profile
- Biological profile analysis involves studying skeletal remains to determine characteristics like ancestry, age, sex, and population.
- Ancestry estimation is based on skeletal shape and size.
- Age is estimated by analyzing skeletal development, dental eruption patterns, and suture fusion.
- Sex assessment relies on the characteristics of specific skeletal elements.
- Statistical methods are used for evaluating height from long bone lengths.
Recovering Remains
- Clandestine graves require systematic recording of the site's spatial layout before any excavation.
- Ground-penetrating radar aids in locating remains.
- Staging areas are used for processing and documenting remains.
- Samples and data are collected from the site's surroundings.
- Taphonomic context, the environment where the body was buried, helps determine how long the body has been there
Determining Sex
- Sex determination from skeletons uses measurements and shapes (e.g., sciatic notch, subpubic angle, and mastoid process).
- Females typically show a wider pelvic structure and a less prominent brow ridge.
Determining Age
- Age estimation involves the evaluation of skeletal changes.
- Open suture fusion (e.g., coronal, sagittal, lambdoidal, squamosal) helps estimate age. Dental development is also a factor.
Determining Ancestry
- Ancestry can be estimated by analyzing facial features and other distinctive skeletal traits.
Estimating Time of Death
- Trauma analysis assesses the presence and timing of injuries.
- The condition of bones and bone tissue is also analyzed in conjunction with forensic anthropological findings.
- Bone analysis examines the presence of broken bones as well as factors like diseases and toxicology associated exposure
Importance of Forensic Anthropology
- Identifying skeletal remains as human or non-human
- Establishing a biological profile of the victim (age, sex, etc.)
- Assisting in identifying missing persons
- Applying techniques developed in 1849 to skeletal analysis
- Using facial reconstructions to identify remains
Skeletal Biology and Geography
- Strontium levels in bones can help determine the geographic origin of the individual.
- Analyzing bone structure and characteristics provide clues about diet, physical activity, or environmental factors
Skeletal Trauma
- Bone trauma analysis assesses injuries prior to, during, and after death.
- Various types of trauma can be analyzed on bone, including injuries from blunt force, sharp force, or gun shot wounds.
- Injuries are often compared to patterns present in injuries observed in injuries inflicted during physical altercations, domestic violence, or in other specific events.
- Animal or insect gnaw marks, insect activity on bones, or other similar patterns can also be examined by forensic anthropologists.
Analysis of Skeletal Remains
- Determining the cause of death, trauma, disease, or other conditions that may have affected the individual
- Evaluating bone fracture characteristics or patterns in relation to how or why these fractures may have developed
- Utilizing DNA analysis when appropriate for identifying a decedent
- Applying appropriate skeletal analysis and comparison to medical records, dental records, or other sources of information.
- Using photographic and video superimpositions, models, or reconstructions for creating an approximation of the appearance of the decedent
DNA Analysis
- Nuclear DNA analysis from skeletal remains helps with identification.
- When compared with a relative's DNA, the individual can be identified.
