This thesis testedseven already existing (sets of) formulae using dental root translucency as a parameter, that weredeveloped on samples from various geographical regions, on the known sex and age-at-death sample from the Middenbeemster Collection housed at the Laboratory of Human Osteoarchaeology at the Faculty of Archaeology in Leiden University, The Netherlands. A total of 77 individuals werestudied, resulting in age-at-death estimations for 67 of theseindividuals. To test if a more accurate formula could be developed for the Middenbeemster Collection, and even Dutch osteoarchaeological human remains, several new formulaewere trailedresulting in the following formula (T = translucency in mm):Age =19.832+7.667*T +-0.299*T2.With this formula, no statistical difference was found between males and females and seemed not to be affected by dental disease.The new formula was tested on twenty-onenew individuals from the Middenbeemster Collection and twenty individuals from Arnhem, Eusebiuskerk, allonly having an estimated osteological age category. The newly derived formula performed well in the forty-one newly studied individuals, bringing the total number of studied individuals with an age-at-death estimation to 108 individuals. The small sample size and slight underrepresentation should be addressed in future research that either has to enlarge the known age-at-death sampleand/or enlarge the estimated age-at-death sampleto test the presented formula of this thesis.Show less

Few extant methods have been able to match the accuracy rates of methods designed for adult remains and those that have failed to achieve similarly acceptable rates when tested on a population other than the one on which the method was originally developed. Due to this, children are habitually excluded from archaeological investigations since a major component of their biological profiles is considered inaccessible. A definitive and reliable technique to estimate sex in non-adult osteological remains would contribute greatly to the field of osteoarchaeology, allowing for the refinement of osteological age estimation and growth studies as well as more perceptive interpretations of the social, economic, or environmental implications of osteological evidence. In this thesis, a population-specific statistical approach to non-adult sex estimation based on the crown and cervical dimensions of the permanent canines and maxillary first molars was tested on the documented post-medieval skeletal collection of Middenbeemster, the Netherlands. The odontometrics of the adult component of the population (n = 76) were used to develop 14 binomial logistic regression formulae, which were subsequently applied to the non-adult individuals of the same population (n = 15). Though the two formulae based on the maxillary first molar odontometrics performed little better than chance, all 12 of the formulae based on the permanent canines achieved accuracy rates above 75%, with eight surpassing 85% and five achieving 100% accuracy. It was demonstrated that as little as one dimension of the permanent maxillary or mandibular canine can be used to estimate sex with an acceptable level of confidence. Due to the necessity of a permanent canine, this method is only applicable to individuals aged five years and above at the time of death, including adult individuals whose state of preservation does not allow for morphometric sex estimation or whose morphological sex estimate was indeterminate. By allowing reliable sex estimation in non-adult skeletal remains, this method makes it possible to gain insights into the past lives of non-adult individuals, who all too often seem invisible in archaeological and historical narratives.Show less

Due to the absence of decisive archaeological evidence as to the identity of the sea peoples, countless researcher has speculated about the sea peoples’ identity on the basis of the archaeological and historical evidence that was thus far available. These sources of evidence are, however, far from decisive as evidenced from the countless competing theories regarding the identity of the sea peoples and the part they played in the destruction of the great states that defined the Near East and the Aegean during the 12th century B.C.E. In this thesis, I will investigate how the application of ancient DNA studies may help us to broaden our insight into the sea peoples’ identity and origin. The limitations and opportunities of ancient DNA analysis will be outlined and the prospects it provides will be highlighted. The available DNA studies of interest will be examined and studied to shed new light on the identity of the sea peoples the role thy played in the wide dynamics of the 12th century Aegean.Show less
