1. Introduction
Venturing into disaster victim identification remains a core forensic anthropological practice that aids identification efforts regarding individuals who lose their lives due to natural disasters as well as terrorist attacks and pandemics together with aviation accidents. The traditional DVI methods rely on three primaries sources of evidence: DNA analysis and dental data along with fingerprints. Forensic anthropology now proves necessary when conventional identification methods fail to recognize human remains that exist as either skeletal elements or decayed or broken parts. Recent progress and upcoming developments and existing hurdle in using Forensic Anthropology for DVI form the focus of this article.
2. Innovations in Forensic Anthropology for DVI.
2.1Advanced Imaging and 3D Reconstruction
The photograph currently serves anthropological purposes to develop multiple components that construct a deceased individual’s biological profile. The quantity of research applying Forensic radiological image techniques with Anthropological methodologies has significantly expanded during the recent years. The use of volume-rendered 3D images remains challenging for immediate application of metric and forensic anthropological methods because scientists cannot identify how such images influence the methodology’s accuracy levels during reference-based or observer-based identification processes
2.2 Computed Tomography (CT) Scanning
The non-invasive features of CT by Hounsfield allowed palaeoanthropology to protect valuable and sometimes fragile fossils of human skeletal remains and mummified remains. The researchers developed special Ning protocols and guidelines specifically for the Technique at the same period. The great density of ancient bones required scientists to create a longer Hounsfield unit scale on which to view internal characteristics properly.
2.3 3D Photogrammetry and Laser Scanning
The application of 3D surface scanners works the same way as computed CT tomography to recreate anthropological samples for registration while also producing illustrations. The anthropologist creates various 3D virtual models that begin with Skull followed by the Coxae and Femur models in addition to other selected zones of interest. The surface scanners record surface features together with surface tone which enables the storage of taphonomic changes like bleaching and solar recoling that occur in the ground. This resolution meets the necessary standards for precise capture of fractures demonstrating plastic or fluted edge disruption as well as lesion detection. Digital scanners produce problems in acquiring sharp energy damage evidence which resolves only when the abnormalities measure two to three millimeters wide. High-end scanners can detect visible little injuries and shallow wounds if the resolution settings are optimized. The documentation methods of trauma abnormalities using 3D Scanners require additional research for advancement.
2.4 Virtual Autopsy and Postmortem Imaging
The recent advance in forensic imaging known as postmortem CT angiography provides additional knowledge regarding soft tissues together with vascular and intestinal damage. Modern cross-sectional imaging applies to virtual anthropological research as well as virtual autopsy investigations. Biological anthropologists use it for comparing bone or dental features between species. The main application involves forensic dancer that helps identify unknown deceased through their remains.
3.DNA and Isotope Analysis in Skeletal Identification
3.1 DNA Analysis
An exclusive inheritance pattern in anthropology allows researchers to analyze mitochondrial DNA through MTDNA making it possible to study material lineages and identify genetic variations that determine ancestral roots and human migration patterns throughout history.
3.2 isotopes
Isotope analysis has proven to be an increasingly useful forensic anthropology investigation technique since the last decade. The present analysis of human remains includes multiple isotopic assessments (C, N, O, H, S, SR, and PB) together with Isotopic Landscape studies of different body tissues (teeth, bones, hair, and nails) for determining a missing person’s origin site.
4. Artificial Intelligence (AI) and Machine Learning
Anthropologists utilize Artificial Intelligence (AI) combined with machine learning methods to examine extensive cultural datasets of equipment such as language and objects and social activities for pattern identification leading to equipment like computer vision and natural Taking advantage to deliver deep understanding of cultural phenomena. AI supports linguistics anthropology and cultural studies and complicated data analysis along with language processing because it helps anthropologists access vital insights from extensive data quantities that exceed manual processing capabilities.
5. Biometric and Craniofacial Identification
The practice of measuring bodily and behavioural traits identifies individual people through biometric identification. The most significant biometric procedures used in forensic anthropology consist of:
5.1Biometric
5.1.1Fingerprint analysis:
A forensic anthropologist executes personal identification via studying the skin if it remains attached to the skeleton although this technique happens only rarely.
5.1.2 Iris and retina scan
The analysis is not commonly used in forensic work yet achieves success with preserved soft tissue samples.
5.1.3 March Analysis:
March Analysis functions in forensic video analysis for the identification of people through their walking behaviours
5.1.4 DNA Profile:
DNA analysis serves as an important and validated tool in forensic anthropology for validating identity by studying genetic markers
5.2 Craniofacial identification
This method identifies identity through analysis of facial and skull structures.
5.2.1 Craniofacial Overlap:
Comparing pictures anticipate with a skull retrieved to evaluate alignment and likely identity.
5.2.2 Facial Approach/Reconstruction:
Using skeletal data to rebuild a likely facial look of the deceased.
5.2.3 Cranial metric analysis:
Anthropometric measures of the skull to establish the ancestry, sex and potential identity.
5.2.4 Morphological comparison:
Visual appraisal of distinctive traits, such as nasal opening form, orbital size and jaw structure.
6. Challenges in Forensic Anthropology for DVI
5.1. Fragmentation and Commission:
Mass disasters generally result in fractured and mixed remains, hindering individual identification.
5.2. Decomposition and charred remnants:
Advanced decomposition, heat damage or exposure to water weaken biological markers.
5.3. The lack of data preceding:
Dental, physicians or DNA records lacking comparative analysis.
5.4. Post-mortem modifications:
Tafonomic influences (eg elimination of elimination, environmental erosion) modify skeletal features.
5.5. Interdisciplinary Coordination:
Requires coordination with dentists, pathologists and geneticists for thorough identification
7. Conclusion
The practice of forensic anthropology remains essential for disaster victim identification purposes during situations which need alternative approaches. The identification process receives considerable accuracy improvement from new image analysis capabilities along with DNA and isotopes systems and AI and biometric recognition technologies. The identification procedures encounter ongoing challenges including environmental aftermath, breakup of remains, ethical problems and discrepancies between international standards. The progress of Forensic Anthropology in DVI will emerge through combined international activities with AI-based systems and collaborative work among different scientific disciplines. By increasing the strength of these sectors forensic identification capabilities will improve thus providing victims’ families with resolution and assisting humanitarian work globally.
