Determining age at death includes examining both bones (which focus on closure of individual bones) and dentation. We can study the eruption and replacement of milk teeth, the sequence of eruption of the permanent dentation, and finally the degree of wear.
This analysation of bones and teeth in particular usually provides us with a relatively accurate idea of the age of an individual.
Archaeologists and anthropologists used to have to rely on either the quality of preservation of remains or the art surrounding the remains to give them an idea of their physical appearance.
However during the ninetieth century German anatomists began attempts to reconstruct faces in order to produce likeness from the skulls of celebrities such as Schiller, Kant and Bach.
The categories most commonly used are fatal (before birth), infant (0-3 years), child (3-12 years), adolescent (12-17 years), young adult (18-30 years), middle adult (30 – 50 years) and old adult (over 50).
Radiocarbon dating is perhaps one of the most commonly employed methods to determine the age of remains.
The method involves calculating the measurement of carbon 14, (a radioactive form of carbon) in material.
Today anthropologists go through a process of using computerized techniques for matching facial proportions and features to create a realistic portrait of the individual.
There are several kinds of evidence which are used to determine the particular foods that people were eating.
