{"title":"Navigating Identity: The Intersection of Social and Biological Identity from the World War II Battle of Tarawa","authors":"Rebecca Taylor, Briana New, C. Tegtmeyer","doi":"10.1353/hub.2017.0098","DOIUrl":"https://doi.org/10.1353/hub.2017.0098","url":null,"abstract":"The 1943 Battle of Tarawa resulted in the loss of approximately 1,000 US service members on or around Betio Island, Tarawa Atoll, Republic of Kiribati. Nearly half these casualties were accounted for after the battle. The Defense POW/MIA Accounting Agency (DPAA) has worked to identify the remaining ~510 unaccounted-for service members and has successfully identified ~160 service members to date. Demographic data pulled from historical documentation of the US losses indicate a relatively homogeneous population (99% White, 81% 17–23 years of age, and only two individuals with a documented religious preference other than Protestant or Catholic). Using this demographic data as a framework, three case studies are presented to demonstrate how a holistic biosocial approach to building identity could facilitate forensic identifications. The temporal and sociocultural contextualization of analyses enables anthropologists to navigate inconsistencies between 21st-century and historical (1940s) social identity concepts to overcome challenges to identification. The case studies demonstrate how biological evidence, genetic evidence, and material evidence (material culture) differently contribute to the social identity of an individual and can impact identification efforts when analytical conclusions are incongruent with historical documentation. The first case of US Battle of Tarawa casualties examines how morphometric biological affinity assessments are biased by the fluidity of social identity concepts when complex morphological and metric indicators of biological affinity are not represented in historical race categories. The second case demonstrates how biogeographic genetic affinity predictions, through a discussion of the G2a4 haplogroup, need to be examined holistically in the context of other lines of evidence. The third case highlights how material evidence can further define social identity beyond physicality, genetic structure, and race. The challenges of interpreting identity from human remains, as highlighted through these examples, are commonly encountered by anthropologists working in disaster victim identification and other humanitarian contexts. Thus, it is imperative for anthropologists to be self-aware of implicit biases toward the current prevailing definitions of biological and social identity and to consider historical perceptions of identity when working in these contexts.","PeriodicalId":13053,"journal":{"name":"Human Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79295060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes may influence the level of genetic similarity between spouses. This study investigates whether genetic similarity in height between husband and wife was influenced by a historical transition in spouse selection criteria. The great transition from the companionate marriage to the individualized marriage occurred in the 1960s. In the companionate marriage, husband and wife chose each other as companions, and the emphasis was on playing marital roles well: husbands being good breadwinners and wives being good homemakers. In the individualized marriage, the emphasis switched to individual feelings, and as a result, when choosing their partners people tended to pay less attention to height, suggesting a smaller genetic correlation for height between spouses. Using data from the Health and Retirement Study, we found that the genetic correlation for height declined substantially in the individualized marriage. We conducted a number of analyses to test for the confounding effects of cohort and age and to address population stratification, selection issues, and genetic relatedness between spouses. Evidence suggests that the effect of this transition is robust.</p>","PeriodicalId":13053,"journal":{"name":"Human Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39530928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Isolation by Distance and the Problem of the Twenty-First Century.","authors":"Shay-Akil McLean","doi":"10.13110/humanbiology.92.3.04","DOIUrl":"https://doi.org/10.13110/humanbiology.92.3.04","url":null,"abstract":"<p><p>Isolation-by-distance models are part of the institutional creed of antiracialism used to critique claims of biological race concepts (BRCs). Proponents of antiracialism appeal to isolation-by-distance models to describe patterns of human genetic differences among and between groups as a function of distance. Isolation by distance has been referred to as the pattern that human genetic variation fits, distributing the differences we see as race throughout geographic space as a series of Gaussian gradients. Contemporary scientific critiques of BRCs fuse social constructionist race concepts with a description of the distribution of proportions of human genetic variation in geographic space as a function of distance. These two points are often followed by statements noting that there is only one human race. How these two concepts connect to each other, and whether or not they connect at all, is unclear in both academic and nonacademic spaces. Consequently, scientists and the public lack an understanding of human population structure and its relationships to varying systems of human interactions. This article reviews isolation-by-distance models in population genetics and the use of these models in the modern problem of human difference. The article presents a historical and conceptual review of isolation-by-distance models and contemporary scientific critiques of BRCs, followed by examples of the use of isolation-by-distance models in studies of human genetic variation. To address the shortcomings in the scientific critique of race, the author proposes combining Du Boisian demography with Darwinian evolutionary biology. From a Du Boisian demographic perspective, race is a product of racism, or race/ism, and is a heredity and inheritance system based on rules of <i>partus sequitur ventrem</i> and hypodescent. Race marks individuals and groups them to reproduce unequal relationships into which Europeans co-opted them. This synthesis propounds a new racial formation theory to understand the more general consequences of racism on genes and health outcomes.</p>","PeriodicalId":13053,"journal":{"name":"Human Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39035802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this serial founder effect (SFE) process has not yet been adequately vetted against other evolutionary processes that may also affect geospatial patterns of diversity. Additionally, studies of the SFE process have been largely based on a limited 52-population sample. In this modestly updated article, originally published in <i>Human Biology</i> in 2016 (vol. 88, no. 3, pp. 219-231), we assess the effects of founder effect, admixture, and localized gene flow processes on patterns of global and regional diversity using a published data set of 645 autosomal microsatellite genotypes from 5,415 individuals in 248 widespread populations. We used a formal tree-fitting approach to explore the role of founder effects. The approach involved fitting global and regional population trees to extant patterns of gene diversity and then systematically examining the deviations in fit. We also informally tested the SFE process using linear models of gene diversity versus waypoint geographic distances from Africa. We tested the role of localized gene flow using partial Mantel correlograms of gene diversity versus geographic distance controlling for the confounding effects of treelike genetic structure. We corroborate previous findings that global patterns of diversity, both within and between populations, are the product of an out-of-Africa SFE process. Within regions, however, diversity within populations is uncorrelated with geographic distance from Africa. Here, patterns of diversity have been largely shaped by recent interregional admixture and secondary range expansions. Our detailed analyses of the pattern of diversity within and between populations reveal that the signatures of different evolutionary processes dominate at different geographic scales. These findings have important implications for recent publications on the biology of race. Our new foreword situates these findings in a long line of anthropological research that categorically rejects racial interpretations of analyses of human diversity.</p>","PeriodicalId":13053,"journal":{"name":"Human Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39036398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
