Transcript of Anthropology
Forensic toxicology is the examining the substance abuse or poisoning of a deceased individual.
Forensic Entomology is the study of insects and anthropod biology to determine facts about a case.
Things you can determine with Forensic Anthropology
Cause of Death
Time of Death
Place of Death
Forensic Psychiatrists determine who can stand trial and how competent suspects/victims are.
Forensic Psychiatrists are commonly used for expert witness/testimony
Forensic Scientists examine blood spatters at crime scenes to understand what happened and how.
From blood spatter analysis, scientists can infer what type object caused the spatter, what angle the spatter came from, and what direction, from looking at the shape and frequent occurance of blood drops/stains.
What is forensic Anthropology?
Forensic anthropology is the examination of human skeletal remains usually for criminal cases. An example being examining marks on a skull to determine cause of death.
How can Anthropology do this?
By analyzing sagittal suture lines on the skull, a forensic anthropologist can examine the age range of a body. If the sagittal line is completely fused together the body is likely older than 35 years old and if the coronal suture was completely fused *(found on the front of the skull) the body is likelky older than 40.
Forensic anthropologists can also indicate the diet and health of an individual by analyzing the teeth. Worn, yellowing teeth can indicate poor diet or smoking while fillings and good dental health indicates the individual could afford dental care and was healthy.
By analyzing the pelvis, anthropologists can determine the age, sex, and whether the individual gave birth. First anthropologists look at the pubic syphysis, the older the individual, the more cracked and pitted the bone is. If there were any soft marks on the pelvis, that indicates childbirth has taken place.To identify gender anthropologists look at the pelvis shape; men have a narrow, deep pelvis and women a wider, shallower pelvis, better suited to carrying a baby.
Anthropologists examine the wrists to determine possible profession. A forensic anthropologist might find a bony ridge on the wrist and decide the dead person may have been someone who used their hands for a living, such as a chef or seamstress.
DNA samples may be taken from any existing hair tissue by anthropologists and positively identify someone, it can also identify a person's race or tribal origins.
Forensic Toxicologists can examine urine, blood, hair, and bodily fluids to test for drugs/poisons.
Fingerprint analyzers can examine fingerprints to identify suspects and rule out other people.
There are three types of fingerprints; loops, whorls, and arches.
EVERY individual has different and unique fingerprints, making it easier to identify certain individuals
When examiners look at bodies, they can tell the place of death by insect eggs and placement on the body. They can also test the blood in bugs found on the body to test for drugs (toxicology)
