Forensic Anthropology

What forensic anthropology actually does inside a criminal investigation, where it sits relative to forensic pathology, odontology and archaeology, the bone-biology baseline (compact vs trabecular bone, Haversian systems, growth plates) every osteologist works from, and the forensic-archaeological scene-recovery protocol that delivers a complete skeleton to the laboratory.

The 206 bones, axial vs appendicular division, the ossification timeline that anchors sub-adult age estimation, side determination and fragment identification on a complete or partial skeleton, the pseudopathology vs pathology vs taphonomy triage every case begins with, and the Buikstra-Ubelaker inventory standards every accredited laboratory follows.

The pelvis as the gold-standard sex indicator (sciatic notch, sub-pubic angle, Phenice 1969 ventral arc / sub-pubic concavity / ischiopubic ramus), the skull and mandible as the secondary indicator (mastoid process, nuchal crest, supra-orbital ridge), long-bone metric and discriminant-function methods, and the sub-adult sex problem that resists all classical morphological approaches.

Sub-adult age from dental eruption sequences (Moorrees, Demirjian, AlQahtani) and epiphyseal fusion timelines, young-adult age from the pubic symphysis (Suchey-Brooks six-phase) and auricular surface (Lovejoy), older-adult age from the sternal rib ends (Iscan-Loth) and cranial sutures (Meindl-Lovejoy), and the multi-method composite and transition analysis approaches that anchor the final age range.

Ancestry estimation from cranial morphology (Howells craniometric, FORDISC discriminant-function software), the modern critique of biological 'race' (the 2020 NIST/AAA position statements), and stature estimation from regression equations (Trotter-Gleser 1952/1958, Pearson, Mukherjee, Pan, Khanpetch and other population-specific equations) plus body-mass estimation from femoral head diameter and other proxies.

Sharp-force trauma (incised wounds, stabs, chops, saw-mark class characteristics and tooth-set / kerf analysis), blunt-force trauma (radiating, concentric and depressed cranial fractures, Hering's principle and the order-of-impact problem), ballistic trauma (entrance vs exit beveling, contact wounds, fragmentation and secondary projectiles), and thermal trauma (calcined bone colour stages, heat-induced fragmentation, crazing patterns).

The decomposition stages framework (fresh, bloat, active decay, advanced decay, skeletonisation) and the Megyesi Total Body Score for accumulated degree days, the Body Farm research stack (ARF Tennessee, STAFS Texas, AFTER Australia, the new FACTS labs), and the taphonomic modifiers (soil chemistry, vertebrate and invertebrate scavenging, fire, water immersion) that warp every PMI estimate.

Comparative radiography for personal ID (frontal sinus, dental, surgical hardware, vertebral and cranial features), photo-to-skull and video superimposition with the Tewari-Iscan critical-reception history, manual and 3D forensic facial approximation (Krogman-Iscan, Wilkinson, Manchester / IFRG protocols), and stable-isotope geographic provenance (Sr, O, Pb, N, C ratios from hair, bone and tooth enamel).

INTERPOL DVI from the osteology side (the MNI / MNE / MLNI minimum-number-of-individuals frame, segregation of commingled remains, biological-profile reconstruction on fragments), war-crimes mass-grave excavation (ICTY Bosnia / Srebrenica, Rwanda Gacaca, Argentina EAAF, Latin American truth-commission work), and the modern mass-disaster casework stack (9/11 WTC fragment ID, 2004 Indian Ocean tsunami, MH17, the Nithari / Aarushi-Hemraj Indian casework).

The accreditation and standards frame: ABFA Diplomate certification (US), SWGANTH / OSAC Anthropology subcommittee, ENFSI Forensic Anthropology Working Group, the BSA 2023 and Crown Court admissibility implications; the repatriation and ethics frame (NAGPRA in the US, the UNDRIP/2018 De Montfort UK precedent, the Hamann-Todd / Terry / Bass and Indian AIIMS / DFSS reference collections); and emerging methods (3D laser scanning, photogrammetry, micro-CT, geometric morphometrics, machine-learning biological profile estimators).
