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 and 2, years old. The work is published July 17 in Scientific Reports. The method targets amelogenin, a protein found in tooth enamel, said first author Tammy Buonasera, postdoctoral researcher working with Glendon Parker, adjunct associate professor in the Department of Environmental Toxicology at the University of California, Davis. Buonasera, Parker, Jelmer Eerkens, professor of anthropology, and colleagues compared three methods for sex determination: the new proteomic method; DNA analysis; and osteology, or analysis of the size, shape and composition of the bones themselves. They applied these methods to remains from two ancestral Ohlone villages near Sunol, California.

Dental Anthropology pp Cite as. Among the many parameters used in studies of prehistoric skeletal series, two are fundamental prerequisites for any statistical analysis: the age at death and the sex of an individual. Various demographic, biological or pathological features can be studied when these parameters are known. Biological age at death assessments are needed for estimating mortality rates, which subsequently have implications for the possible conclusions to be drawn about living conditions, nutritional status, epidemiology, social stratification etc. Unable to display preview.

Sex Determination Using Tooth Dimensions
Sex assessment from tooth measurements can be of major importance for forensic and bioarchaeological investigations, especially when only teeth or jaws are available. The study comprised of dental casts derived from two private orthodontic clinics in Athens. The individuals were randomly selected and all had clear medical history. The mesiodistal crown diameters of all the teeth were measured apart from those of the 3rd molars.
