Can you tell a person’s race by their bones?
It’s impossible to identify a person’s ancestry definitively from a single bone . Investigators can also take bone measurements using calipers, then input the data into a University of Tennessee database containing a reference library of measurements from more than 1,800 bones of known ancestry, age, and gender.
Can you tell if a person is right or left handed from the bones?
Review of the published scientific evidence clearly reveals that observations and measurements of the human skeleton cannot determine handedness with the degree of confidence needed for forensic applications.
Are teeth part of the skeleton?

How do you date a skeleton?
The Carbon 14, or radiocarbon dating method is one of the best-known methods of dating human fossils and has been around since the late 1940s. The Carbon 14 (14C) dating method is a radiometric dating method. A radiometric dating uses the known rate of decay of radioactive isotopes to date an object.
Which frontal bone is lower and sloping?
Male frontal bones are less rounded and slope backwards at a gentler angle.
How do we identify human remains?
DNA analysis is the gold standard for identifying human remains and may be the only available method, when other methods, such as birthmarks, dental records, or fingerprints are not available.
