Teeth chronicle the past. Much like trees, they grow in rings and these rings, or growth marks, act like a record of development.

"Teeth retain the chemical signatures at the time when they were grown, starting at birth and ending in your late teens,” said Diana Malarchik, a Ph.D. candidate in the UC ��ԭ�� Department of Anthropology. “Based on this anatomy, I can sample these growth rings and get nitrogen signatures and create a dietary timeline.”

Archaeologists Use Tooth Enamel Protein to Show Sex of Human Remains

A new method for estimating the biological sex of human remains based on reading protein sequences rather than DNA has been used to study an archaeological site in Northern California. The protein-based technique gave superior results to DNA analysis in studying 55 sets of human remains between 300 and 2,300 years old. The work is published July 17 in Scientific Reports.
