Abstract

This paper discusses the importance of forensic anthropology, which is used as an important tool for the purpose of identification. The significance of present criminological anthropological studies cannot be overemphasized. In criminal cases, mass disaster cases, fire accidents, plane crash accidents, exhumation, bomb blast, and explosion cases the skeletal remains collected by anthropologists are highly deteriorated and fragmented, requiring various methods and techniques to interpret the evidence. Teeth and bones discovered from these events are resistant to degradation processes which act as crucial evidence and serve as a significant tool used for forensic identification hence, forensic anthropology applied for the purpose of identification of skeleton and distinguish other skeletal evidence. Whenever the skeletal evidence is found initially anthropologists determine whether the obtained material is bone or not as the piece of a bone is covered with dust or mixed with alike substances, after assuring that the evidence discovered is bone next they determine that it from human origin or not. Anthropologists generally arranged the pieces of bones in “Anatomical position”. It gives visual information by which the experts can differentiate that the skeletal remains belong to the human origin or animal origin, in addition to that investigators also face some serious issue when several individuals are present at such incidents like mass disaster investigators examines the skeletons separately. After this next step is to determine the age of bones, anthropologists elaborate on the difference between ancient and modern skeleton by examining the extra deposited layer. Biological profiles: age, sex, stature, and ancestry. Skeletal sex should be determined by two methods of forensic anthropology: morphological method or metric method. Morphological methods are based on the concept of sexual dimorphism. Key Words: Sexual Dimorphism, Anatomical Position, Stature, Forensic Anthropology, Skeletal Remains.

Introduction

Identification can be defined as to determine the individuality of a person on the basis of physical or biological traits e.g., sex, age, stature, tattoos, scars, dental estimation, and DNA typing. Identification can be categorized as complete and partial identity (Bardale, 47). Sasouni in 1963 proposed the following techniques for human identification which falls into two groups: Reconstructive group- These systems, utilized on bodies where there is nothing to propose the individual identity, are not concerned with extracted height, race, age, sex, occupation, etc., used for identification. Comparative Group- This method comprises of strategies under which antemortem records and post-mortem records are compared to make proper identification, and it also incorporates radiology (Srivastava et al., 153). Forensic anthropology is a new scientific area that comes under practice is a blended mixture of forensic medicine and physical anthropology. In general terms, this discipline is defined as the utilization of physical human anthropology strategy and systems under the medico-legal system. Even though significant advances have been made in past years in the field of forensic anthropology, various difficulties are still faced by the professionals (Bidmos, Gibbon, Strkalj, 1). Forensic anthropology comes in practice from the late nineteenth century, and known as Alphonse Bertillon’s anthropometric system which is based on principles- After 21years of age the size of the body parts remains the same and the ratio in size among individuals is unique. From a forensic perspective, it is critical to decide the sex of the skeleton stays as right on time as soon as possible under the circumstances (Bardale, 75-76). According to the Krogman, estimation of sex on the basis of skeletal remains is as follows-

• Whole Skeleton – 100%

• Pelvis – 95%

• Skull – 90%

• Pelvis along with the skull – 98%

• Long Bones – 80%

At the point when skeletal remains are discovered, it is important to recreate a natural profile to comprehend the demographics of the population and the individuals this incorporates evaluating age, sex, parentage, and stature and the anthropologists face various challenges at this point. Methods used for skeletal sex diagnosis, forensic anthropologists should have their focus on the accuracy and reliability of the method used for the determination of skeletal sex. Rate of high accuracy may have low reliability. Pelvic bone of the skeleton is only considered portion which has stable sexual dimorphism so that, results of sex determination have positive results with low possible errors. Every single morphological technique utilized for sex determination depends on the presence of sexual dimorphism in the skeleton. Sexual dimorphism is brought about by the presence of various sex chromosomes and with the growth of males and females. Consequently, it is unimaginable to expect to decide the sex of non­adult people with fundamental accuracy and unwavering quality as during ontogeny the degree of sexual dimorphism in the skeleton is low. Another factor is the constant inconstancy in the improvement of sex characteristics that appear differently in relation to the elective nature of the two sex classifications (Bruzek and Veleminsky, 46).
