Forensic anthropology
When looking at bones, anthropologists look for markings left on bones caused by stress. These markings are called stress markers or occupation markers. Occupational markers can be found in cases where muscles or tendons insert into the cortical tissue of bone via the periosteum, or where there is hypertrophy of muscular attachments on the bones. The cause of the markers left are from repetitive activities over a long period of time. But some studies do not think occupational markers are very helpful for forensic identification and may be a source of bias.
