Forensic anthropology what is it
Abnormal changes in the shape, size and density of bones can indicate disease or trauma. Bones marked by perimortem injuries, such as unhealed fractures, bullet holes, or cuts, can reveal cause of death. The trained anthropologist is also able to identify skeletal clues of ancestry. Even certain activities, diet, and ways of life are reflected in bones and teeth.
The remains may represent victims of violence or natural disasters. In these cases Smithsonian anthropologists work with the FBI , State Department, and other law enforcement agencies to identify the individuals and solve crimes.
They also conduct research on historic and prehistoric human remains to learn more about people from the past. As Smithsonian forensic anthropologist Kari Bruwelheide says, "The bones are like a time capsule.
Smithsonian anthropologist Dr. Douglas Owsley , examining a skeleton from historic Jamestown , discovered evidence of chops to the skull from an axe or other sharp bladed, implement. Knife cuts were also observed on the bone. Along with other information such as biological indicators and discovery location of the remains, Dr. Owsley concluded that a year-old girl had been cannibalized after she died. His discovery supported other historic data that the colonists of Jamestown suffered severe starvation during the harsh winter of Anthropologists at the National Museum of Natural History use a variety of techniques to analyze human remains and record their observations.
For example, the bones are typically photographed and X-rayed. Some remains may undergo CT scanning or be examined with high-powered microscopes. These techniques provide detailed information about remains without altering them while providing a visual record.
DNA analysis may be used to help establish identity. This type of testing is most often used in modern forensic case work, but mitochondrial DNA in bones and teeth can be used to confirm relationships of old remains with deceased or living descendants. The data gathered is studied and combined to draw conclusions about the deceased individual. Over the past century, physical anthropologists have developed methods to evaluate bones to understand people who lived in the past.
Such questions might include: Was this individual male or female? How old were they when they died? How tall were they? Were the people in good or poor general health?
