Experiment 11. Examination of Human Hair
Normally any hair found at a crime scene or on a body is examined with a microscope to determine if it is of human or animal origin. If human, the hair is typically identified to be from a particular anatomic region (somatic region) of the human body, for example, head or pubic. Next, the questioned hair is identified as originating from a person of particular ancestry, for example, eastern European, African, or Asian. Finally, the questioned hair is compared to known hair standards to see if the hair could have originated from a particular person or have a common origin. It is important to note that questioned hairs from a particular anatomic region of the body can only be compared to known hairs from the same region.
