The emergence of biomedical anthropology and its implications for the future

Primarily during the past 15 years a distinct new area within physical anthropology has emerged, biomedical anthropology. Physical anthropologists have become heavily involved in studying problems of relevance to the health and illness patterns of living humans. There has been a proportionate increase in biomedically focused papers published in the American Journal of Physical Anthropology, in biomedically focused papers presented at annual meetings of the American Association of Physical Anthropologists, and in physical anthropology doctoral dissertations oriented toward modern biomedical phenomena. Proportionately more physical anthropologists are now employed in medical schools and there has been recent growth in the proportion of physical anthropologists in anthropology departments who claim some aspect of biomedical anthropology as a research interest. Increasingly, physical anthropologists are focusing their research on cardiovascular disease, the leading cause of death in America. These distinct trends are partially a result of the nature of physical anthropology and its unique biocultural perspective. However the growth of applied anthropology, the present academic marketplace, and the availability of research funds are probably also contributing factors. The emergency of biomedical anthropology holds promise for the future of physical anthropology and for its current employment crisis. Careers with academic and nonacademic organizations engaged in biomedical research appear to be a viable alternative to careers in departments of anthropology, for biomedical anthropologists. This will entail some reorientation of graduate training for physical anthropologists. More emphasis will have to be placed on substantive biomedical subjects, research methods, and data management and analysis.     

The State of Biological Anthropology in 2008: Is Our Discipline Strong and Our Cause Just?

ABSTRACT   Biological anthropologists inform a largely professional discourse on the evolutionary history of our species. In addition, aspects of our biology, the ways in which we vary, and certain patterns of behavior are the subjects of a more public and popular conversation. The social contexts in which we work not only define our times but also produce the anthropologists that in turn construct an emergent understanding of our species' (and our societies') inner workings. In this review of scholarly production, I focus on developments within a selection of "sub-subdisciplines" that were particularly influential in bending the arc of biological anthropology in 2008, namely: evolutionary medical anthropology, anthropological neuroscience, forensic anthropology, primatology, and paleoanthropology. Ultimately, this review demonstrates, yet again, anthropology's great contribution: the ability to incorporate new technologies and research methodologies into a synthetic and integrative interdisciplinary approach toward the elucidation of human behavior, evolution, and biocultural engagements with the environment.

Skeletal biological distance studies in American physical anthropology: recent trends

Biological distance analysis, the dominant type of skeletal biological research during the 19th century, has become less visible in recent years. Although the proportion of American Journal of Physical Anthropology articles and published abstracts focusing on biodistance has remained fairly constant over the three decades between 1955 and 1985, the proportion of biodistance contributions relative to other skeletal biology studies has decreased. Emphasis in skeletal biology has shifted from the analysis of biological variation to investigations of health and diet, and within biodistance studies methodological issues have assumed prominence over purely analytical approaches. This paper investigates trends in biological distance analysis through a survey of articles and meetings abstracts published in the American Journal of Physical Anthropology from 1955 to 1985. The survey provides the historical context for five symposium papers on skeletal biological distance presented at the 1986 meeting of the American Association of Physical Anthropologists.

Erratum

The Table of Contents in the January 1997 issue, AJPA 102:1, did not differentiate between articles published as part of an edited symposium, and other research papers published in that issue. Five of the first six articles (pp. 1-77) in volume 102:1 were originally presented at the 63rd AAPA annual meeting (1994) as part of a symposium entitled “Social and Political-Economic Perspectives in Biological Anthropology.” The organizers of the symposium, and its counterpart published in AJPA 102:1, were T.L. Leatherman and A.H. Goodman.     

The growth of growth

Over a 40-year period, 1940 through the present, human growth research has increased from a minimal to a major part of physical anthropology. Such research, originally conducted at the major American growth centers, has become more diverse and more specialized, extending to National Probability Samplings, nutritional surveys, studies of twins, investigations restricted to the craniofacial complex, and studies of the growth and development of various primate species. Besides extending knowledge of growth and development in general and control mechanisms in particular, there has been major feedback into physical anthropology affording far greater understanding of human variability, of taxonomic differences, and of changes previously believed to be phylogenetic in nature. To the larger extent, all physical anthropologists have some degree of growth awareness.     

Knowledge from the Margins: W. Montague Cobb's Pioneering Research in Biocultural Anthropology

W. Montague Cobb became the first African American to receive a doctorate in physical anthropology in the United States (1932). He was also among the first U.S. physical anthropologists to demonstrate a commitment to biocultural integration and racial equality in his research. Nonetheless, very few European American physical anthropologists responded to or utilized Cobb's work. This continued after bioanthropology took on a more biocultural focus in the 1980s, some 50 years after Cobb's first studies of this kind. In this essay, I highlight Cobb's research and writing from the first decades of his career to illustrate his contribution to developing biocultural perspectives in physical anthropology. As a result, I hope to move Cobb from the margins to the center of discussions about methodological and theoretical developments in bioanthropology over the past 30 years.     

Physical anthropological approaches to aging

The field of gerontology is remarkably diverse; yet there has been relatively little investigation of physical anthropological issues in aging research. This review explores gerontologic topics of actual and/or potential interest to physical anthropologists. The evolution of aging presents a theoretical dilemma in that postreproductively expressed traits may be outside the influence of natural selection. The physiological changes of aging comprise a diversified mosaic of physical deterioration as would be expected from an evolutionary model. Studies of prehistoric aging are limited to estimating lifespan, which may not be indicative of rate of aging. Considerable attention has been devoted to body composition and aging, and notable findings include a loss of lean tissue with age and relatively constant (though redistributing) fat mass. Osteoporosis is a major problem of aging in females, as is tooth loss in both sexes. The study of variation in rates of aging is only beginning, and a number of approaches to measuring biological age in adulthood are presented. Determining the associations of lifestyle, economic, and nutritional status with biological age may reveal sources of variation in rates of aging and may be of practical importance.     

Plains History and Cultural Anthropology

Abstract

Recent cutbacks in research funding and the burgeoning population of anthropology graduate departments may soon force cultural anthropologists to recognize what their archaeological colleagues have long known: their own “backyard” is a field for fertile research. Specifically, cultural anthropologists may turn increasingly to using long-neglected data sources - rich in documentation - on Anglo-Saxon America. This paper briefly investigates some reasons for the study of American historical data and presents a preliminary analysis of some data.     

Physiological anthropology: past and future

Environmental studies in adaptive human biology by North American anthropologists have a history of strong investigative research. From both laboratory and field work, we have gained major insights into human response to physical and social challenges. While these results were considered by most professionals to belong within evolutionary biology, in fact the intellectual structure sprang almost entirely from physiological equilibrium models. Consequently, physiological process itself was the focus. Further, most of the physiological patterns were not linked directly to important outcomes such as work output, reproductive success or survival.About 1975, American physiological anthropologists, led by Paul Baker, turned to studies of health, change and stress response. These studies were strong, but were still neither genetic nor evolutionary in intellectual structure. Evolutionary human biology was taken over by a new body of theory now called "behavior ecology", positing that selfish genes control human behavior to promote their own reproduction. This was paralleled by strong use of evolutionary theory in some areas of molecular biology. However, although physiological anthropologists have not focused on evolution, we have been developing powerful causal models that incorporate elements of physiology, morphology, physical environment and cultural behavior. In these "proximate" biocultural models, it is of little importance whether outcomes such as work or energy management are genetically based.Our future offers two major challenges. First, we must confirm causal links between specific physiological patterns and outcomes of practical importance to individuals and societies. Second, if we are to take our place in evolutionary biology, the one overarching theory of life on earth, we must understand the heritability of physiological traits, and determine whether they play a role in survival and reproduction.     

From the ground up: Integrative research in primate locomotion

Primate locomotor adaptation and evolution is a principal and thriving area of research by biological anthropologists. Research in this field generally targets hypotheses regarding locomotor kinetics and kinematics, form–function associations in both the soft and hard tissue components of the musculoskeletal system, and reconstructing locomotor behavior in fossil primates. A wide array of methodological approaches is used to address adaptive hypotheses in all of these realms. Recent advances in three-dimensional shape capture, musculoskeletal physiological measurements, and analytical processing technologies (e.g., laser and CT-scans, 3D motion analysis systems, finite element analysis) have facilitated the collection and analysis of larger and more complex locomotor datasets than previously possible. With these advances in technology, new methods of form–function analyses can be developed to produce a more thorough understanding of how form reflects an organism's mechanical requirements, how shape is influenced by external environmental factors, and how these investigations of living taxa can inform questions of primate paleobiology. The papers in this special section of the American Journal of Physical Anthropology present research that builds on that foundation, by combining new data on living primates and new methodologies and approaches to answer a range of questions on extant and extinct primates.

Biological anthropology's critical engagement with genomics,evolution, race/racism,and ourselves: Opportunities and challenges to making a difference in the academy and the world

Biological anthropology can, and should, matter in the Anthropocene. Biological anthropologists are interested in human biology and the human experience in a broader ecological, evolutionary, and phylogenetic context. We are interested in the material of the body, the history of the body, and interactions of diverse bodies, communities, ecologies, and evolutionary processes. However, the cultural realities of bodies, histories, communities, livelihoods, perceptions, and experiences are as central to the endeavor and inquiry of biological anthropology as are their material aspects. Biological anthropology is a constant dialectic between the cultural and the biological. In this essay, I argue that Biological Anthropology has much to offer, a history to contend with, and a future that matters. To illustrate this, I highlight theoretical and methodological issues in genomics, evolutionary theory and connect them to the study of Race and Racism to emphasize specific arenas where Biological Anthropology has a great capacity, and a strong obligation, to play a central role. However, Biological Anthropology also has substantive internal issues that hinder our ability to do the best possible science. If we are to live up to our potential and make a difference in the 21st century we need to ameliorate our structural shortcomings and expand our voice, and impact, in academic and public discourse. The goal of this perspective is to offer suggestions for moving us toward this goal.     

Mitochondrial DNA analysis reveals substantial Native American ancestry in Puerto Rico

To estimate the maternal contribution of Native Americans to the human gene pool of Puerto Ricans--a population of mixed African, European, and Amerindian ancestry--the mtDNAs of two sample sets were screened for restriction fragment length polymorphisms (RFLPs) defining the four major Native American haplogroups. The sample set collected from people who claimed to have a maternal ancestor with Native American physiognomic traits had a statistically significant higher frequency of Native American mtDNAs (69.6%) than did the unbiased sample set (52.6%). This higher frequency suggests that, despite the fact that the native Taíno culture has been extinct for centuries, the Taíno contribution to the current population is considerable and some of the Taíno physiognomic traits are still present. Native American haplogroup frequency analysis shows a highly structured distribution, suggesting that the contribution of Native Americans foreign to Puerto Rico is minimal. Haplogroups A and C cover 56.0% and 35.6% of the Native American mtDNAs, respectively. No haplogroup D mtDNAs were found. Most of the linguistic, biological, and cultural evidence suggests that the Ceramic culture of the Taínos originated in or close to the Yanomama territory in the Amazon. However, the absence of haplogroup A in the Yanomami suggests that the Yanomami are not the only Taíno ancestors.

Promoting synergistic research and education in genomics and bioinformatics

Bioinformatics and Genomics are closely related disciplines that hold great promises for the advancement of research and development in complex biomedical systems, as well as public health, drug design, comparative genomics, personalized medicine and so on. Research and development in these two important areas are impacting the science and technology.High throughput sequencing and molecular imaging technologies marked the beginning of a new era for modern translational medicine and personalized healthcare. The impact of having the human sequence and personalized digital images in hand has also created tremendous demands of developing powerful supercomputing, statistical learning and artificial intelligence approaches to handle the massive bioinformatics and personalized healthcare data, which will obviously have a profound effect on how biomedical research will be conducted toward the improvement of human health and prolonging of human life in the future. The International Society of Intelligent Biological Medicine (http://www.isibm.org) and its official journals, the International Journal of Functional Informatics and Personalized Medicine (http://www.inderscience.com/ijfipm) and the International Journal of Computational Biology and Drug Design (http://www.inderscience.com/ijcbdd) in collaboration with International Conference on Bioinformatics and Computational Biology (Biocomp), touch tomorrow's bioinformatics and personalized medicine throughout today's efforts in promoting the research, education and awareness of the upcoming integrated inter/multidisciplinary field. The 2007 international conference on Bioinformatics and Computational Biology (BIOCOMP07) was held in Las Vegas, the United States of American on June 25-28, 2007. The conference attracted over 400 papers, covering broad research areas in the genomics, biomedicine and bioinformatics. The Biocomp 2007 provides a common platform for the cross fertilization of ideas, and to help shape knowledge and scientific achievements by bridging these two very important disciplines into an interactive and attractive forum. Keeping this objective in mind, Biocomp 2007 aims to promote interdisciplinary and multidisciplinary education and research. 25 high quality peer-reviewed papers were selected from 400+ submissions for this supplementary issue of BMC Genomics. Those papers contributed to a wide-range of important research fields including gene expression data analysis and applications, high-throughput genome mapping, sequence analysis, gene regulation, protein structure prediction, disease prediction by machine learning techniques, systems biology, database and biological software development. We always encourage participants submitting proposals for genomics sessions, special interest research sessions, workshops and tutorials to Professor Hamid R. Arabnia (hra@cs.uga.edu) in order to ensure that Biocomp continuously plays the leadership role in promoting inter/multidisciplinary research and education in the fields. Biocomp received top conference ranking with a high score of 0.95/1.00. Biocomp is academically co-sponsored by the International Society of Intelligent Biological Medicine and the Research Laboratories and Centers of Harvard University--Massachusetts Institute of Technology, Indiana University--Purdue University, Georgia Tech--Emory University, UIUC, UCLA, Columbia University, University of Texas at Austin and University of Iowa etc. Biocomp--Worldcomp brings leading scientists together across the nation and all over the world and aims to promote synergistic components such as keynote lectures, special interest sessions, workshops and tutorials in response to the advances of cutting-edge research.     

Molecular and physiological manifestations and measurement of aging in humans

Biological aging is associated with a reduction in the reparative and regenerative potential in tissues and organs. This reduction manifests as a decreased physiological reserve in response to stress (termed homeostenosis) and a time‐dependent failure of complex molecular mechanisms that cumulatively create disorder. Aging inevitably occurs with time in all organisms and emerges on a molecular, cellular, organ, and organismal level with genetic, epigenetic, and environmental modulators. Individuals with the same chronological age exhibit differential trajectories of age‐related decline, and it follows that we should assess biological age distinctly from chronological age. In this review, we outline mechanisms of aging with attention to well‐described molecular and cellular hallmarks and discuss physiological changes of aging at the organ‐system level. We suggest methods to measure aging with attention to both molecular biology (e.g., telomere length and epigenetic marks) and physiological function (e.g., lung function and echocardiographic measurements). Finally, we propose a framework to integrate these molecular and physiological data into a composite score that measures biological aging in humans. Understanding the molecular and physiological phenomena that drive the complex and multifactorial processes underlying the variable pace of biological aging in humans will inform how researchers assess and investigate health and disease over the life course. This composite biological age score could be of use to researchers seeking to characterize normal, accelerated, and exceptionally successful aging as well as to assess the effect of interventions aimed at modulating human aging.     

The importance of fallback foods in primate ecology and evolution

The role of fallback foods in shaping primate ranging, socioecology, and morphology has recently become a topic of particular interest to biological anthropologists. Although the use of fallback resources has been noted in the ecological and primatological literature for a number of decades, few attempts have been made to define fallback foods or to explore the utility of this concept for primate evolutionary biologists and ecologists. As a preface to this special issue of the American Journal of Physical Anthropology devoted to the topic of fallback foods in primate ecology and evolution, we discuss the development and use of the fallback concept and highlight its importance in primatology and paleoanthropology.
