Anthropologists can help identify a deceased from his or her skeletal remains bearing characteristics of ancestry, sex, stature, age and trauma. Conduct a couple of visual comparison techniques, explore Liliana Pereyra's case, and get a glimpse into the work of three anthropologists.
Learning from bones
Bones bear numerous clues that can help anthropologists determine who the person was and how they died. When deciphered, these cluses may serve as evidence in a courtroom.
Take a close look at these two skulls. Compare the different views of the two—especially the areas marked. Do you see any differences that help you identify the sex of each skull? Now click on the male or female button and see if you got it right! View hints.
Skulls bear various characteristics that provide clues about the person's ancestry/race to experienced anthropologists. Now take a close look at the frontal and profile views of the nose area (nasal bone, opening, spine and sill) and guess the ancestry of this person. View hints.
Bullet entry and exit wound
There is a clear distinction between entry and exit wounds made by a bullet. Take a close look at each wound, and determine which is the entry wound and which is the exit. View hints.
