Multiple choice

What is the primary role of a forensic anthropologist?

  1. To identify human remains

  2. To determine the cause of death

  3. To reconstruct the crime scene

  4. To collect evidence for law enforcement
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary role of a forensic anthropologist is to identify human remains, often in cases where the remains are badly decomposed or fragmented.

Multiple choice

Which of the following is NOT a method used by forensic anthropologists to identify human remains?

  1. DNA analysis

  2. Dental records

  3. Fingerprint analysis

  4. Anthropometric measurements
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fingerprint analysis is not a method used by forensic anthropologists to identify human remains. DNA analysis, dental records, and anthropometric measurements are all commonly used methods.

Multiple choice

What is the term for the process of determining the race of human remains?

  1. Age estimation

  2. Sex estimation

  3. Stature estimation

  4. Race estimation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Race estimation is the process of determining the race of human remains. It is based on a number of factors, such as the shape of the skull, the size of the nasal aperture, and the texture of the hair.

Multiple choice

What is the term for the study of human remains in a legal context?

  1. Cultural anthropology

  2. Biological anthropology

  3. Archaeology

  4. Forensic anthropology
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forensic anthropology is the study of human remains in a legal context. It focuses on the ways in which human remains can be used to identify victims of crime, determine the cause of death, and reconstruct the crime scene.

Multiple choice
