Forensic Anthropology: Definition, History and Application

What is Forensic Anthropology?

Forensic anthropology is a specialized branch of physical anthropology that deals with the medico-legal purpose to establish the identity of the deceased person. It uses the knowledge of human anatomy like the size of bones, hairs, length, features of bones, teeth, etc to determine the person's age, sex, stature, and race. In some cases, it can also predict the cause of death of the person by studying the different features on the bone.

Forensic Anthropology

Forensic anthropologists are often called to the scene of the crime to study the remains of human remains which got decomposed, burned, mutilated, or difficult to recognize. Forensic anthropology can be used in accident cases like aircraft crashes, arson, fire accidents, genocide, etc.

History of Forensic Anthropology

The history of forensic anthropology dates back to the 19th century when anatomists were often asked for human identification through their skeletal. In 1835, Mathieu Orfila, a french forensic medicine expert published a textbook containing data on measurements of arm bones and their sex difference.

In 1889, E.Rollet developed tables for male and female stature reconstruction from bone lengths. In 1885, Alphonse Bertillon developed the famous Bertillon identification system which depends on the body measurements of individuals. Till now, forensic anthropology has undergone extensive research and development.

Role of Forensic Anthropologist

  1. Forensic anthropologist helps to recover and analyze human remains that are decomposed or skeletonized rapidly and efficiently.
  2. Forensic anthropologist helps to find the biological characteristics of the body like its age, sex, race-ethnicity, and height. This can be done through the study of the bones of the dead body.
  3. Forensic anthropologists can also help to distinguish between bones of different species like human and animal, male and female, infant and adult, etc.
  4. Forensic anthropologist also helps to reconstruct the scene of the crime as well as natural and intentional changes to the body and the surroundings.
  5. Forensic anthropologists can also help in research purposes like making public travel safe. For eg- By studying the fractures on different parts of the body of a variety of individuals. He/she can make recommendations in changing the structure/design of car seats that can save human lives if any accident happens in the future.

Application of Forensic Anthropology

1. Determination of species

Forensic anthropology can help in the determination of species by studying the characteristics of bones and skulls. This helps to distinguish between different species like human and animal, male and female, infant and adult.

2. Determination of age

Forensic anthropology can help in the determination of the age of individuals by studying the union of centers of the bones. The growth and certain changes in bones and teeth help the investigator in determining the age of the individual at the time of death.

3. Determination of sex

Forensic anthropology can help in the determination of sex by studying different morphological differences between males and females. For eg- The pelvis of the female is wider than the male.

4. Determination of Race 

Forensic anthropology can help in the determination of race by studying morphological characteristics that are confined to an individual of a particular race. Based on these, the racial group t which the individual belongs can be identified.

5. Determination of Height

Forensic anthropology can help in the determination of height by applying formulae to calculate the length of individual bones, especially the long bones of limbs.

Conducting Polymers: Definition, Examples, Properties and Applications

What are Conducting Polymers? As the name suggests organic polymers that conduct electricity are known as conducting polymers. They are also known as intrinsically conducting polymers (ICPs) and they have alternating single and double bonds along the polymer backbone (conjugated bonds) or that are composed of aromatic rings such as Phenylene, naphthalene, anthracene, pyrrole, and thiophene which are connected through carbon-carbon single bonds. Examples: Polyacetylene, Polypyrrole, Polyaniline, etc What is the reason behind conducting nature of these polymers? Conducting polymers comes in two forms that are doped conducting polymers and non-doped conducting polymers. The conductivity of non-doped conjugated polymers is due to the existence of a conductivity band similar to a metal. In a conjugated polymer, three of the four valence electrons form strong sigma bonds through sp² hybridization where electrons are strongly localized. The remaining unpaired electron of each carbon atom re...

Crime Scene: Definition, Types and Characteristics

What is a Crime Scene ? A place where the crime is committed or where the maximum physical evidence related to crime is found is known as a crime scene. A crime scene is a starting point of the investigation which provides information about the suspect and the victim. This helps to reconstruct the crime and fast resolution of the case. It is noted that the crime scene is not limited to a single place but may extend to a wider area depending upon the nature of the crime committed. For example, In a murder case where murder is done at one place and the body is disposed on another place. In this case, we have two crime scenes that give information about the crime. Types of Crime Scene Based on evidence found on the crime scene: 1. Primary Crime Scene The crime scene where the actual crime occurred or where more usable pieces of evidence were found is known as the primary crime scene. For example, A murder scene, theft, assault, etc. 2. Secondary Crime Scene The crime scene which is some...

Documentation of the Crime Scene: Step by Step

Image
What is documentation of the crime scene and Why it is done? After securing the crime scene, the next most important step is documentation of the crime scene because documentation permanently records the crime scene and its physical evidence. Documentation should be done without any wastage of time as the scene and its evidence may get altered over time. The documentation should be done innovatively and the originality of the crime scene should be maintained and documentation should not have pauses or breaks, it should remain constant till the whole crime scene is documented. There are four main tasks of documentation that is note-making, photography, videography , and sketching . It should be noted that all four tasks are necessary and none is a substitute for another. For example, notes are not substitutes for photography, video is not a substitute for sketching, etc. Following are the sequence for crime scene documentation: 1. Note making Documentation of crime scene in the f...
