Summary Backgroud The current article is part of the paper presented at the Colloque International Anthropo-Responsabilite (28–29 janvier 2021–musee du quai Branly–Jacques Chirac, Paris). Methodology The Teaching and Research Centre of Forensic Archaeology and Anthropology (NEPAAF) at the Laboratory of Archaeological Studies (LEA) from the Federal University of Sao Paulo (UNIFESP) have developed a pioneer project which deals with the compilation and organization of documentary data (antemortem phase), preparation, curation and bioanthropological analysis of the skeletons (postmortem phase) of an identified osteological collection of the Institute of Teaching and Research in Forensic Sciences (IEPCF) in order to conduct research and provide advanced training in Forensics. The IEPCF collection currently includes 143 unclaimed skeletons with extensive documentation including sex, age-at-death, statute, ancestry, place of birth and death, date of birth/death and cause of death were obtained from the public cemetery records. Identified osteological collections have been traditionally used to develop and test methods in Forensic Anthropology to identify the biological profile through estimation of age-at-death, sex, stature, and ancestry. Given the history of Brazil, the amassing of osteological reference collections is an important a challenge to be overcome to address the reality of violence and death. The main goal of the project is to create an anthropological sample to maximize the research and training potential, and to adapt international standard procedures and methods to Brazilian forensic contexts. Results-discussion Reliminary results from assessing ancestry methods using this collection are presented in this paper to assess some of the ethical and human implications of the continued use of race and ancestry in forensic anthropology. Using a sub-sample of 36 individuals (21 males and 15 females), two major methods were tested for their utility in a forensic context. Both the morphoscopic and metric methods performed poorly. Given the parameters of the blind testing, both methods provided reliable information that matched antemortem records equivalent to chance, and in 47–50% of the cases provide wrong information. Conclusion The results have implications for the adaption of methods to a forensic context in Brazil, and internationally with respect to human rights investigations.

In this paper we present a new methodology for developing sample-specific metric sex determination methods using unidentified individuals that can be applied to archaeological samples. This methodology does not require the assessment of sex of a large sample from pelvic morphological features as a first step in developing the method and instead is developed from a sample of individuals with sex unknown. The procedure involves using the overall mean of a measurement collected from the sample of unknowns as the ...

Secular changes or secular trends are non-genetic changes that occur over multiple generations in a population. The changes are not due to evolution because there are no corresponding changes in allele frequencies in the population. These changes typically correspond with changes in living conditions and are reflected in the population means for growth and development, and not necessarily in any one individual. The most studied secular change is change in stature or height. Improvements in living conditions have resulted in measurable increases or positive secular changes in stature from parents to children. The most obvious cases have been observed when comparing first generation immigrants to their children. Conversely, decreases or negative secular changes in mean population stature from parents to children have been documented when living conditions worsen due to natural disasters, wars, or prolonged economic hardships. Several sources of data can be used for the study of secula...

"Accurate and precise assessments of sex and age at death of human skeletal remains are the essential first steps in the bioarchaeological reconstruction of past human populations, including patterns of morbidity and mortality, demographic reconstruction, diet and health, mobility and social status. Identified skeletal collections have been indispensable for developing and testing the methods used to estimate age and sex. The value of these collections is entirely based on the quality of the documentary information for any one individual and for a collection as a whole. However, there are limitations and pitfalls involved in research using identified collections. How does a researcher know if ‘known ages’ are indeed correct? If a collection has been curated over the course of many decades, does it constitute a population, or simply an assembly of individuals unrelated in time and space? How should such a collection be sampled? Further problems and limitations associated with each collection are context-specific; for instance, the politico-economic context of the collection process can have an enormous impact on the structure and composition of the collection. Why were some skeletons included in the collection and have the retained documentary data been assessed for accuracy? Drawing on our experience conducting research using various identified collections from around the world (Coimbra, Dart, Forensic Anthropology Databank, Grant, Huntington, Lisbon, Pretoria, Spitalfields and Terry), in this paper we present some practical suggestions for overcoming the possible problems with reference collections and maximizing their research potential.

A comprehensive model that builds on cemetery studies theory and new biocultural synthesis theory is presented for investigating human variation using reference collections. This model is used to investigate several hypotheses related to the use of skeletal reference collections and the race concept in skeletal biology. Are racial categories or equivalent terms useful for investigating human variation? Have biases in reference collections resulted in a misinterpretation of human variation? Is it possible to identify and control for some of the biases in reference collections and develop identification methods that are still useful in the 21st century? Documentary, historical and skeletal data were collected from two different reference collections: the Terry and Coimbra Collections. Some data from the Forensic Anthropology Data Bank (FDB) were also used in conjunction with these two collections in analyses related to patterns of sexual dimorphism, sex determination methods, and asse...

Sex estimation from skeletal remains can be an important part of preliminary identification. The best source of information for estimating sex is the pelvis but it is not always available for analysis. For these cases, a probabilistic sex estimation method is presented using combinations of standard and alternative measurements of the clavicle, humerus, radius, and ulna. Various equations are developed that are not population specific and that are applicable in various recovery scenarios. The equations were tested using four independent samples (n > 370), including a forensic sample. Allocation accuracies vary by test sample and equation and are consistently good (87.4-97.5%) except for a sample of very small males that show the extreme effects of poverty and mortality bias. For many of the cases where allocation was incorrect, the probabilistic approach indicated that no confidence should be placed in the incorrect allocation and the unknown should be classified as sex indeterminate.

An estimate of stature can be used by a forensic anthropologist with the preliminary identification of an unknown individual when human skeletal remains are recovered. Fordisc is a computer application that can be used to estimate stature; like many other methods it requires the user to assign an unknown individual to a specific group defined by sex, race/ancestry, and century of birth before an equation is applied. The assumption is that a group-specific equation controls for group differences and should provide the best results most often. In this paper we assess the utility and benefits of using group-specific equations to estimate stature using Fordisc. Using the maximum length of the humerus and the maximum length of the femur from individuals with documented stature, we address the question: Do sex-, race/ancestry- and century-specific stature equations provide the best results when estimating stature? The data for our sample of 19th Century White males (n=28) were entered into Fordisc and stature was estimated using 22 different equation options for a total of 616 trials: 19th and 20th Century Black males, 19th and 20th Century Black females, 19th and 20th Century White females, 19th and 20th Century White males, 19th and 20th Century any, and 20th Century Hispanic males. The equations were assessed for utility in any one case (how many times the estimated range bracketed the documented stature) and in aggregate using 1-way ANOVA and other approaches. This group-specific equation that should have provided the best results was outperformed by several other equations for both the femur and humerus. These results suggest that group-specific equations do not provide better results for estimating stature while at the same time are more difficult to apply because an unknown must be allocated to a given group before stature can be estimated.

The use of cadaver length and forensic stature as a proxy for living standing height has not been scrutinized in detail. In this paper we present a brief review of the current knowledge on the relationship between cadaver, living and forensic stature; assess the magnitude and nature of the differences between these three measures of stature; and investigate the potential impact of these differences in forensic contexts. The study uses a sample of 84 males who were autopsied in 2008 at the National Institute of Legal Medicine and Forensic Sciences (Porto, Portugal), where stature data were collected from three different sources: cadaver stature was obtained from the corpse prior to autopsy, living stature was obtained from military conscription records and forensic stature was obtained from national citizenship identification card records. Descriptive statistics, ANOVA and linear regression are used to analyze the data. The results show that cadaver stature is the highest measure, fo...

An accurate and precise estimate of stature can be very useful in the analysis of human remains in forensic cases. A problem with many stature estimation methods is that an unknown individual must first be assigned to a specific group before a method can be applied. Group membership has been defined by sex, age, year of birth, race, ancestry, continental origin, nationality or a combination of these criteria. Univariate and multivariate sex-specific and generic equations are presented here that do not require an unknown individual to be assigned to a group before stature is estimated. The equations were developed using linear regression with a sample (n=244) from the Terry Collection and tested using independent samples from the Forensic Anthropology Databank (n=136) and the Lisbon Collection (n=85). Tests with these independent samples show that (1) the femur provides the best univariate results; (2) the best multivariate equation includes the humerus, femur and tibia lengths; (3) ...

In some jurisdictions, race, ancestry, or population affinity have been used for historical and po-litical, rather than biological, reasons in forensic anthropology when identifying individuals. The approach persists even though the genetic and skeletal data clearly demonstrate that human variation does not cluster into these groups. For over 60 years, these methods have consistently performed poorly when independently tested using large samples. By racializing the deceased, these methods have further marginalized the living. However, there is a need in the investigation of genocide and human rights violations to demonstrate that a specific group was targeted. Without relying on the outdated typological concepts of human variation, in this paper we present preliminary results for a method that can be used in a mass grave context to demonstrate that a specific group was targeted. Using samples from two identified reference collections, we created subsamples from one relatively homoge...

The sourcing of cadavers for North American skeletal reference collections occurred immediately after death and targeted the poor and marginalised. In Europe, collections sourced bodies that were buried and unclaimed after some time in cemeteries with no perpetual care mandate, and may have also targeted the underprivileged. The relationship between socio-economic status (SES) and abandonment was examined in a sample of unclaimed remains (603 adults and 98 children) collected from cemeteries in the city of Lisbon, Portugal, that were incorporated in a collection. Results demonstrate that low SES individuals are not more likely to be abandoned nor to be incorporated in the collection than higher SES individuals. Furthermore, historical data indicate that the poorest were not incorporated into the collection, because of burial practices. Although the accumulation of collections in North America was facilitated by structural violence that targeted the poor and marginalised, this phenom...

Demonstrating the importance of bite-mark evidence within the forensic science community is extremely valuable in order to retain its legitimacy. This was illustrated by using techniques and analyses to match a bite-mark impression back to the specimen in which it originated. Bite-marks are known as a number of bruised markings on the skins surface, often in a semi-lunar shape produced by a human with a particular set of teeth. When referring to a particular set of teeth, class and individual characteristics need to be examined within that dentition. 20 bite-mark impressions were created within clay using 10 skeletal mandibles and 10 skeletal maxillas. 60 trials were performed in order to examine whether or not the given cast and impression are a match or no match to one another. 57 out of 60 trials were successful, giving a 95% success rate in determining the correct outcome. However, 3 of out 60 trials were unsuccessful. The success rate of the performed trials provides evidence t...

In some jurisdictions, race, ancestry or population affinity are part of the biological profile used in preliminary identification, for historical and political reasons. It is long overdue for forensic anthropologists to abandon this typological approach to human variation, regardless of the terms used. Using a sample (n = 105) selected from the Terry and Coimbra identified reference collections, a blind experimental approach is used to test several metric methods and versions of methods for group estimation (Fordisc 3.0 and 3.1, and AncesTrees), that rely on different statistical approaches (discriminant function analysis and random forest algorithms, respectively) derived from different reference samples (Howells’ data in AncesTrees and Fordisc 3.1, and different forensic subsamples in Fordisc 3.0 and 3.1). The accuracy for matching premortem documented group designation is consistently low (36 to 50%) across testing parameters and consistent with other independent tests. The resu...

Since the earliest descriptions of the pubis length measurement, it has been recognized that the location of the key landmark in the acetabulum has to be estimated. Using samples from the Terry Collection (n = 324) and the Coimbra Collection (n = 232), the purpose of this research is to, first, test the reproducibility of a new alternative to the traditional measurement of the pubis, and second, to use the best measurement of the pubis along with other measurements of the hipbone and femur to develop a metric method that can be used with confidence to determine the sex of individuals of various geographic origins and time periods. In this study, it was found that, first, the alternative pubis measurement, known as the superior pubis ramus length (SPRL), can be collected more reliably with less mean intra-observer error (0.57%) than the more commonly used manner of measuring the pubis (2.7%). Second, a logistic regression sex determination method using the SPRL, along with other measurements of the hipbone and femur, has an allocation accuracy of 90% to 98.5% (depending on the model used and the manner of testing) across independent samples. Third, traditional racial categorization was irrelevant to the accuracy of the method. Fourth, measurement error greater than 2% in the measurement of the pubis can be the difference between a correct and an incorrect allocation of sex, particularly in borderline cases.

Laser scanning technology is increasingly being used in forensic anthropological research to obtain virtual data for archival purposes and post hoc measurement collection. This research compared the measurement accuracy of two laser scanners-the FARO Focus(3D) 330X and the FARO Freestyle(3D) -against traditionally obtained (i.e., by hand) control data (N = 454). Skeletal data were collected to address a novel question: the ability of laser scanning technology to produce measurements useful for biological characteristic estimation, such as sex and stature. Results indicate that both devices produced measurements very similar to control (c. 3-mm average absolute error), but also illuminate a tendency to under-measure. Despite these findings, the virtual data produced sex and stature estimates that varied little from control-produced estimates, signifying the usefulness of virtual data for preliminary biological identification when the skeletal elements are no longer available for phys...

ABSTRACT A comprehensive model that builds on cemetery studies theory and new biocultural synthesis theory is presented for investigating human variation using reference collections. This model is used to investigate several hypotheses related to the use of skeletal reference collections and the race concept in skeletal biology. Are racial categories or equivalent terms useful for investigating human variation? Have biases in reference collections resulted in a misinterpretation of human variation? Is it possible to identify and control for some of the biases in reference collections and develop identification methods that are still useful in the 21st century? Documentary, historical and skeletal data were collected from two different reference collections: the Terry and Coimbra Collections. Some data from the Forensic Anthropology Data Bank (FDB) were also used in conjunction with these two collections in analyses related to patterns of sexual dimorphism, sex determination methods, and assessment of secular changes using skeletal data. A critical review of the methodology for the study of secular change in femur length illustrates that there are methodological costs of ignoring bias in reference collections. In a combined sample from several collections, what appear to be significant secular changes occur at the points of transition between data sources. Dividing samples into racial sub-samples does not control for so-called population differences and only further confounds the analysis of secular changes using reference collections. An alternative methodology was followed for the development of a series of metric sex determination methods with allocation accuracies of 90-98.5%. Logistic regression was used to develop a series of models that use a new alternative measurement of the pubis along with traditional measurements of the hipbone and femur. Demographic and historical data were used to select a reference sample that included a wide range of human variation. Testing suggests that these metric models are widely applicable. Various skeletal, demographic, and historical analyses indicated that racial categories or equivalent terms are not useful for investigating human variation using reference collections, and that some of the biases in reference collections have resulted in a mis-interpretation of human variation in past research. It is possible to identify and control for some of the biases in reference collections and develop identification methods that are still useful in the 21st century.
