These computational tools provide powerful insights gained from genomic datasets, although they are generally inaccessible to those with less computational experience.

Despite decades of research, methods for providing an estimate of the PMI with known error rates are still absent from applied medicolegal forensic work, which prompts the necessity for a critical examination of the state of the field. This review details the history of how forensic anthropology emerged from the broader discipline of biological anthropology, with a specific focus on how forensic anthropologists came to be understood as suitable experts for estimating the PMI. We describe existing PMI estimation methods and enduring barriers in advancing our knowledge. We provide an overview of the formative PMI research, then focus on a systematic review of 30 years (1993-2023) of human decomposition literature. Results of our synthesis demonstrate the two prevailing ways to estimate the PMI involve (1) the use of quantitative biomarkers and (2) macromorphoscopic observations. Results also highlight that PMI research continues to be limited by small, highly variable samples and a lack of standardized definitions of decomposition, which impedes replicability and the advancement of methods for PMI estimation. Forensic anthropologists can address these longstanding issues by ensuring the principles of Open Science are adhered to during the research and dissemination process including data sharing and transparency. Intentional research design that integrates comprehensive geospatial data and improved modeling techniques can contribute to devising methods capable of providing PMI estimates within applied medicolegal and humanitarian contexts.</p>","PeriodicalId":29759,"journal":{"name":"American Journal of Biological Anthropology","volume":"186 Suppl 78 ","pages":"e70011"},"PeriodicalIF":1.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11898555/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We then review the ways QDA has been used in six subfields of biological anthropology: primatology, human biology, paleoanthropology, dental and skeletal biology, bioarchaeology, and anthropological genetics. We follow that with an overview of how to use QDA methods: three simple QDA methods (i.e., word-based analysis, theme analysis, and coding) and three QDA approaches for model-building and model-testing (i.e., content analysis, semantic network analysis, and grounded theory). With this foundation in place, we discuss how QDA can support transformative research in biological anthropology-emphasizing the valuable role of QDA in inductive and community-based research. We discuss how QDA supports transformative research using mixed-methods research designs, participatory action research, and abolition and Black feminist research.

Namely, what makes humans different from other animals, and how did we get this way? Many relevant traits are physical, but many others are behavioral. For example, when and why did our species develop complex cognition, enduring bonds, and intense cooperation? Given the importance of behavior, biological anthropologists have a long history of turning to our primate relatives to generate hypotheses about the evolutionary processes shaping humans. Indeed, primate behavior is foundational to our field. But not all biological anthropologists appreciate the value of primate behavior for understanding human evolution. Beyond lip service in introductory paragraphs and grant proposals, many primatologists do not make explicit how their work is relevant to human evolution. In this review, we have three main goals: (1) emphasize how comparative studies of primate behavior are crucial to biological anthropology; (2) outline how primatologists and biological anthropologists can improve their work by avoiding common problems that arise when making such comparisons; and (3) provide a primer on the concepts and methods underlying comparative analyses of traits. We provide examples to highlight these points related to cognition, sociality, and diet. We conclude with several recommendations including (1) detailed, high-quality studies of behavior that allow for appropriate comparisons within and across species; (2) using primates as a \"gateway clade\" and expanding our research to any relevant taxa; and (3) careful attention to the ethical implications of making comparisons to other primates given racist tropes and a history of eugenics.</p>","PeriodicalId":29759,"journal":{"name":"American Journal of Biological Anthropology","volume":"186 Suppl 78 ","pages":"e70009"},"PeriodicalIF":1.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
