However, quantitative data and focused investigations on the behavioral ecology of solitary male individuals or all-male groups are limited. White-headed langurs (<i>Trachypithecus leucocephalus</i>) live in small groups, with one-male bisexual groups as the basic social unit.

Robust capuchins, the genus &lt;i&gt;Sapajus&lt;/i&gt;, are an excellent convergent model system for understanding tool use evolution, principally in the context of foraging, in terms of how they use stones to process hard fruits. However, most published studies of capuchin tool use in the wild focus on the species &lt;i&gt;Sapajus libidinosus&lt;/i&gt;. In order to strengthen comparative analyses, it is important to do research across robust capuchin species to understand tool use capacities and variation across the genus. The first indirect evidence that reported tool use in wild &lt;i&gt;S. xanthosternos&lt;/i&gt; was in 2009, but since that time no additional publications have described this behavior for this species. In this study we provide the first complete characterization of tool use in wild &lt;i&gt;S. xanthosternos&lt;/i&gt; for two areas within Montes Claros, Minas Gerais state, Brazil: Santa Rosa de Lima district, and Lapa Grande State Park. We compare our findings to the stone tool use characteristics reported in wild &lt;i&gt;Sapajus libidinosus&lt;/i&gt; and other capuchin monkey species.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Materials and Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;In monthly surveys from January to September 2018, we walked trails through the two study areas and categorized tool use site characteristics, including anvil area, height, and perimeter; hammer stone weight; and species of fruit utilized.

The authors of this special issue describe the ethical challenges surrounding the collection, curation, and use of human skeletal remains in biological anthropology, focusing particularly on the historical exploitation of marginalized communities, such as Indigenous and African American populations. These remains were often acquired without consent through colonial exploitation and unethical practices like grave robbing. This introduction presents a historical review of the dehumanization of these remains, which have been treated as scientific specimens rather than as individuals with complex histories. We highlight the ongoing misuse of human remains in academic settings and the perpetuation of structural violence. The papers in this special issue call for the development of ethical guidelines that emphasize transparency, respect for descendant communities, and the consideration of non-destructive research methods. The authors advocate for rehumanizing these remains, fostering collaboration with descendant communities, and supporting efforts for repatriation.

As part of this maturity, and in step with other branches of science and the humanities, forensic anthropology has also experienced an upswing in discourse on decolonization and decoloniality. From its inception and throughout its history, anthropology has been a colonial venture that observes humans under a Western gaze. As a critique of the universality and superiority of Western systems of knowledge, the decolonial turn constitutes alternative ways of thinking and doing and provides space for these epistemes to circulate and thrive. In this synthesis, decolonization efforts within forensic anthropology are organized into five “C's” of appraisal: categories, casework, curricula, competence, and collections. Namely, these efforts feature the debates around sex, ancestry, and structural vulnerability estimation (categories); the expansion of humanitarian action and community involvement and the challenges to positivism, neutrality, and objectivity (casework); the assessment of how we educate, train, and value expertise (curricula and competence); and the interrogation of how we extract knowledge from the dead (collections). From the undercurrents of these five, a sixth C, care, is unveiled. Given the academic and practical value of forensic anthropology, especially vis-à-vis its consequences for colonized peoples, these discourses become imperative for the continued relevance of a colonialist field in a postcolonial world.</p>\u0000 </div>","PeriodicalId":29759,"journal":{"name":"American Journal of Biological Anthropology","volume":"186 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423853","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}
