Towards “A Natural History of Data”: Evolving Practices and Epistemologies of Data in Paleontology, 1800–2000

The fossil record is paleontology’s great resource, telling us virtually everything we know about the past history of life. This record, which has been accumulating since the beginning of paleontology as a professional discipline in the early nineteenth century, is a collection of objects. The fossil record exists literally, in the specimen drawers where fossils are kept, and figuratively, in the illustrations and records of fossils compiled in paleontological atlases and compendia. However, as has become increasingly clear since the later twentieth century, the fossil record is also a record of data. Paleontologists now routinely abstract information from the physical fossil record to construct databases that serve as the basis for quantitative analysis of patterns in the history of life. What is the significance of this distinction? While it is often assumed that the orientation towards treating the fossil record as a record of data is an innovation of the computer age, it turns out that nineteenth century paleontology was substantially “data driven.” This paper traces the evolution of data practices and analyses in paleontology, primarily through examination of the compendia in which the fossil record has been recorded over the past 200 years. I argue that the transition towards conceptualizing the fossil record as a record of data began long before the emergence of the technologies associated with modern databases (such as digital computers and modern statistical methods). I will also argue that this history reveals how new forms of visual representation were associated with the transition from seeing the fossil record as a record of objects to one of data or information, which allowed paleontologists to make new visual arguments about their data. While these practices and techniques have become increasingly sophisticated in recent decades, I will show that their basic methodology was in place over a century ago, and that, in a sense, paleontology has always been a “data driven” science.     

The Rebirth of Kinship

Kinship was one of the key areas of research interest among anthropologists in the nineteenth century, one of the most hotly debated areas of theory in the early and mid-twentieth century, and yet an area of waning interest by the end of the twentieth century. Since then, the study of kinship has experienced a revitalization, with concomitant disputes over how best to proceed. This special issue brings together recent studies of kinship by scientific anthropologists employing evolutionary theory and quantitative methods. We argue that the melding of the evolutionary theoretical perspective with quantitative and ethnographic methodologies has strengthened and reinvigorated the study of kinship by synthesizing and extending existing research via rigorous analyses of evidence.     

Built for speed,not for comfort. Darwinian theory and human culture

Darwin believed that his theory of evolution would stand or fall on its ability to account for human behavior. No species could be an exception to his theory without imperiling the whole edifice. The ideas in the Descent of Man were widely discussed by his contemporaries although they were far from being the only evolutionary theories current in the late nineteenth century. Darwin's specific evolutionary ideas and those of his main followers had very little impact on the social sciences as they emerged as separate disciplines in the early Twentieth Century. Not until the late twentieth century were concerted, sophisticated efforts made to apply Darwinian theory to human behavior. Why such a long delay? We argue that Darwin's theory was rather modern in respects that conflicted with Victorian sensibilities and that he and his few close followers failed to influence any of the social sciences. The late Twentieth Century work takes up almost exactly where James Baldwin left off at the turn of the century.     

Lateral and Vertical Transfer in Biology,Linguistics and Anthropology: An Account of Widely Neglected Ideas in the Formation of Evolutionary Theories

The scope of this paper is to highlight models of reticulate evolution in a dual sense: (1) by stressing the importance of early models of horizontal/lateral transfer instead of models of unilinear vertical transfer in biology, linguistics, anthropology and related disciplines, and (2) by demonstrating that the acceptance of evolutionism as leitmotif in the nineteenth century was only possible by intense and repeated networks between scholars of different academic realms which lead to the assumption that the development of biological species and human cultures could be perceived as part of the same co-evolutionary process. Contrary to these widely popularized models of unilinear evolution, I would like to draw attention to alternative theories emphasizing the horizontal transfer of words, phenotypes/genotypes, and culture traits. Examples are the method of areal typology in linguistics, the theory of endosymbiosis in biology, and the anti-evolutionist attitude in Boasian anthropology, combined with an emphasis on the diffusion of culture traits. Further, it shall be pointed out that, even when—after the general dismissal of evolutionist ideas in the beginning of the twentieth century—the idea of co-evolutionary processes in the development of human populations and languages was again forwarded in the late twentieth century, this ‘modern synthesis’ of genetics, linguistics and archeology relied largely on interdisciplinary reticulations between sciences and humanities and serves as another example of reticulate evolution.     

Koch's postulates and the etiology of AIDS: an historical perspective.

This paper examines the debate over the human immunodeficiency virus (HIV) as the cause of acquired immunodeficiency syndrome (AIDS) from an historical perspective. The changing criteria for proving the link between putative pathological agents and diseases are discussed, beginning with Robert Koch's research on anthrax in the late nineteenth century. Various versions of 'Koch's postulates' are analyzed in relation to the necessity and sufficiency arguments of logical reasoning. In addition, alterations to Koch's postulates are delineated, specifically those required by the discovery of rickettsiae and viruses in the early twentieth century and by the immunological testing developed after mid-century to demonstrate the links between elusive viral agents and two diseases, hepatitis B and infectious mononucleosis. From this perspective, an examination of the AIDS debate is constructed. Molecular biologist Peter Duesberg's argument that HIV is not the cause of AIDS is analyzed in light of his contention that a version of Koch's postulates has not been satisfied. Additional research findings through 1990 relating to the etiology of AIDS are also noted.     

Diffusion theory in biology: a relic of mechanistic materialism

Diffusion theory explains in physical terms how materials move through a medium, e.g. water or a biological fluid. There are strong and widely acknowledged grounds for doubting the applicability of this theory in biology, although it continues to be accepted almost uncritically and taught as a basis of both biology and medicine. Our principal aim is to explore how this situation arose and has been allowed to continue seemingly unchallenged for more than 150 years. The main shortcomings of diffusion theory will be briefly reviewed to show that the entrenchment of this theory in the corpus of biological knowledge needs to be explained, especially as there are equally valid historical grounds for presuming that bulk fluid movement powered by the energy of cell metabolism plays a prominent note in the transport of molecules in the living body. First, the theory's evolution, notably from its origins in connection with the mechanistic materialist philosophy of mid nineteenth century physiology, is discussed. Following this, the entrenchment of the theory in twentieth century biology is analyzed in relation to three situations: the mechanism of oxygen transport between air and mammalian tissues; the structure and function of cell membranes; and the nature of the intermediary metabolism, with its implicit presumptions about the intracellular organization and the movement of molecules within it. In our final section, we consider several historically based alternatives to diffusion theory, all of which have their precursors in nineteenth and twentieth century philosophy of science. This revised version was published online in July 2006 with corrections to the Cover Date.     

Hybrids, pure cultures, and pure lines: from nineteenth-century biology to twentieth-century genetics

Prompted by recent recognitions of the omnipresence of horizontal gene transfer among microbial species and the associated emphasis on exchange, rather than isolation, as the driving force of evolution, this essay will reflect on hybridization as one of the central concerns of nineteenth-century biology. I will argue that an emphasis on horizontal exchange was already endorsed by 'biology' when it came into being around 1800 and was brought to full fruition with the emergence of genetics in 1900. The true revolution in nineteenth-century life sciences, I maintain, consisted in a fundamental shift in ontology, which eroded the boundaries between individual and species, and allowed biologists to move up and down the scale of organic complexity. Life became a property extending both 'downwards', to the parts that organisms were composed of, as well as 'upwards', to the collective entities constituted by the relations of exchange and interaction that organisms engage in to reproduce. This mode of thinking was crystallized by Gregor Mendel and consolidated in the late nineteenth-century conjunction of biochemistry, microbiology and breeding in agro-industrial settings. This conjunction and its implications are especially exemplified by Wilhelm Johannsen's and Martinus Beijerinck's work on pure lines and cultures. An understanding of the subsequent constraints imposed by the evolutionary synthesis of the twentieth century on models of genetic systems may require us to rethink the history of biology and displace Darwin's theory of natural selection from that history's centre.     

The Australian Dominative Medical System: A Reflection of Social Relations in the Larger Society

This paper posits a working or tentative model of medical pluralism, a pattern in which multiple medical sub‐systems co‐exist, or what I term the Australian dominative medical system. I argue that whereas the Australian medical system with its various medical sub‐systems was pluralistic, that is more or less on an equal footing, in the nineteenth century, by the early twentieth century it became a plural or dominative one in the sense that biomedicine came to clearly dominate other medical sub‐systems. This paper also explores the growing interest of biomedicine and the Australian Government in complementary medicine to which Australians have increasingly turned over the course of the past three decades or so.     

The Riddle of Sex: Biological Theories of Sexual Difference in the Early Twentieth-Century

At the turn of the twentieth century, biologists such as Oscar Riddle, Thomas Hunt Morgan, Frank Lillie, and Richard Goldschmidt all puzzled over the question of sexual difference, the distinction between male and female. They all offered competing explanations for the biological cause of this difference, and engaged in a fierce debate over the primacy of their respective theories. Riddle propounded a metabolic theory of sex dating from the late-nineteenth century suggesting that metabolism lay at the heart of sexual difference. Thomas Hunt Morgan insisted on the priority of chromosomes, Frank Lillie emphasized the importance of hormones, while Richard Goldschmidt supported a mixed model involving both chromosomes and hormones. In this paper, I will illustrate how the older metabolic theory of sex was displaced when those who argued for the relatively newer theories of chromosomes and hormones gradually formed an alliance that accommodated each other and excluded the metabolic theory of sex. By doing so, proponents of chromosomes and hormones established their authority over the question of sexual difference as they laid the foundations for the new disciplines of genetics and endocrinology. Their debate raised urgent questions about what constituted sexual difference, and how scientists envisioned the plasticity and controllability of this difference. These theories also had immediate political and cultural consequences at the turn of the twentieth century, especially for the eugenic and feminist movements, both of which were heavily invested in knowledge of sex and its determination, ascertainment, and command.     

Advanced microscopic and histochemical techniques: diagnostic tools in the molecular era of myology

Over the past two centuries, myology (i.e. the basic and clinical science of muscle and muscle disease) has passed through 3 stages of development: the classical period, the modern stage and the molecular era. The classical period spans the last part of nineteenth century and the earlier part of the twentieth century. During this time, several major muscle diseases were clinically and pathologically characterized, including Duchenne muscular dystrophy (DMD), myotonic dystrophy (DM) and facioscapulohumeral dystrophy (FSHD). The modern stage in the second half of the twentieth century is characterized by the adaptation of histo and cytochemical techniques to the study of muscle biopsies. These tools improved the diagnostic accuracy and made possible the identification of new changes and structures (Engel and Cunningham, 1963; Scarlato, 1975).     

Towards a definition of Islamophobia: approximations of the early twentieth century

This paper contributes to the debate on the meaning of the term ‘Islamophobia’. It proposes an examination of the early twentieth-century approaches to Islamophobia, both the term and the phenomenon. The aim is to show that the phenomenon had already been identified at the end of the nineteenth century and that it had been defined by the beginning of the twentieth. That definition could throw some light on the current debate about the meaning of the term.     

Graphing evolutionary pattern and process: a history of techniques in archaeology and paleobiology

Graphs displaying evolutionary patterns are common in paleontology and in United States archaeology. Both disciplines subscribed to a transformational theory of evolution and graphed evolution as a sequence of archetypes in the late nineteenth and early twentieth centuries. U.S. archaeologists in the second decade of the twentieth century, and paleontologists shortly thereafter, developed distinct graphic styles that reflected the Darwinian variational model of evolution. Paleobiologists adopted the view of a species as a set of phenotypically variant individuals and graphed those variations either as central tendencies or as histograms of frequencies of variants. Archaeologists presumed their artifact types reflected cultural norms of prehistoric artisans and the frequency of specimens in each type reflected human choice and type popularity. They graphed cultural evolution as shifts in frequencies of specimens representing each of several artifact types. Confusion of pattern and process is exemplified by a paleobiologist misinterpreting the process illustrated by an archaeological graph, and an archaeologist misinterpreting the process illustrated by a paleobiological graph. Each style of graph displays particular evolutionary patterns and implies particular evolutionary processes. Graphs of a multistratum collection of prehistoric mammal remains and a multistratum collection of artifacts demonstrate that many graph styles can be used for both kinds of collections.     

Darwin's legacy: the forms,function and sexual diversity of flowers

Charles Darwin studied floral biology for over 40 years and wrote three major books on plant reproduction. These works have provided the conceptual foundation for understanding floral adaptations that promote cross-fertilization and the mechanisms responsible for evolutionary transitions in reproductive systems. Many of Darwin''s insights, gained from careful observations and experiments on diverse angiosperm species, remain remarkably durable today and have stimulated much current research on floral function and the evolution of mating systems. Here I review Darwin''s seminal contributions to reproductive biology and provide an overview of the current status of research on several of the main topics to which he devoted considerable effort, including the consequences to fitness of cross- versus self-fertilization, the evolution and function of stylar polymorphisms, the adaptive significance of heteranthery, the origins of dioecy and related gender polymorphisms, and the transition from animal pollination to wind pollination. Post-Darwinian perspectives on floral function now recognize the importance of pollen dispersal and male outcrossed siring success in shaping floral adaptation. This has helped to link work on pollination biology and mating systems, two subfields of reproductive biology that remained largely isolated during much of the twentieth century despite Darwin''s efforts towards integration.     

Rapid adaptation: a new dimension for evolutionary perspectives in ecology

Although the study of adaptation is central to biology, two types of adaptation are recognized in the biological field: physiological adaptation (accommodation or acclimation; an individual organism’s phenotype is adjusted to its environment) and evolutionary–biological adaptation (adaptation is shaped by natural selection acting on genetic variation). The history of the former concept dates to the late nineteenth and early twentieth centuries, and has more recently been systemized in the twenty-first century. Approaches to the understanding of phenotypic plasticity and learning behavior have only recently been developed, based on cellular–histological and behavioral–neurobiological techniques as well as traditional molecular biology. New developments of the former concepts in phenotypic plasticity are discussed in bacterial persistence, wing di-/polymorphism with transgenerational effects, polyphenism in social insects, and defense traits for predator avoidance, including molecular biology analyses. We also discuss new studies on the concept of genetic accommodation resulting in evolution of phenotypic plasticity through a transgenerational change in the reaction norm based on a threshold model. Learning behavior can also be understood as physiological phenotypic plasticity, associating with the brain–nervous system, and it drives the accelerated evolutionary change in behavioral response (the Baldwin effect) with memory stock. Furthermore, choice behaviors are widely seen in decision-making of animal foragers. Incorporating flexible phenotypic plasticity and learning behavior into modeling can drastically change dynamical behavior of the system. Unification of biological sciences will be facilitated and integrated, such as behavioral ecology and behavioral neurobiology in the area of learning, and evolutionary ecology and molecular developmental biology in the theme of phenotypic plasticity.     

Innateness and the Brain

The philosophical innateness debate has long relied onpsychological evidence. For a century, however, a parallel debate hastaken place within neuroscience. In this paper, I consider theimplications of this neuroscience debate for the philosophicalinnateness debate. By combining the tools of theoretical neurobiologyand learning theory, I introduce the ``problem of development' that alladaptive systems must solve, and suggest how responses to this problemcan demarcate a number of innateness proposals. From this perspective, Isuggest that the majority of natural systems are in fact innate. Lastly,I consider the acquistion strategies implemented by the human brain andsuggest that there is a rigorous way of characterizing these ``neuralconstructivist' strategies as not being strongly innate. Alternatives toinnateness are thus both rigorously definable and empirically supported.     

Effects of metabolic rate on protein evolution

Since the modern evolutionary synthesis was first proposed early in the twentieth century, attention has focused on assessing the relative contribution of mutation versus natural selection on protein evolution. Here we test a model that yields general quantitative predictions on rates of protein evolution by combining principles of individual energetics with Kimura's neutral theory. The model successfully predicts much of the heterogeneity in rates of protein evolution for diverse eukaryotes (i.e. fishes, amphibians, reptiles, birds, mammals) from different thermal environments. Data also show that the ratio of non-synonymous to synonymous nucleotide substitution is independent of body size, and thus presumably of effective population size. These findings indicate that rates of protein evolution are largely controlled by mutation rates, which in turn are strongly influenced by individual metabolic rate.     

Developmental capacitance, genetic accommodation, and adaptive evolution

The concept of genetic accommodation remains controversial, in part because it remains unclear whether evolution by genetic accommodation forces a revolution, or merely a shift in emphasis, in our understanding of how evolution produces adaptive new traits. Here I outline a perspective that largely favors the latter view. I argue that evolution by genetic accommodation can easily be integrated into traditional evolutionary concepts. At the same time, evolution by genetic accommodation invites novel empirical and theoretical approaches that may allow biologists to push the boundaries of our current understanding of the process of evolution and to solve some long-standing controversies. Specifically, I discuss the role of developmental mechanisms as natural, and likely ubiquitous, capacitors of cryptic genetic variation, and the role of environmental perturbations as mechanisms by which such variation can become visible to selection on an individual to population-wide scale. I argue that in combination, developmental capacitance and large-scale environmental perturbations have the potential to facilitate rapid evolution including the origin of novel adaptive features while circumventing otherwise powerful genetic and population-biological constraints on adaptive evolution. I end by highlighting several promising avenues for future empirical research to explore the mechanisms and significance of evolution by genetic accommodation.     

The Altyerre Story—‘Suffering Badly by Translation’

In culture‐contact situations, it is commonplace for words to be borrowed from other unrelated vernaculars, for their pronunciations to be changed, and their meanings modified to fit new contexts. The Arandic word altyerre is a rather extreme example of this, and at the end of the nineteenth century, the ‘translation’ of the related word Alcheringa as ‘dream‐times’ sparked a debate that, in some forms, continues to this day. In this article, I discuss some of the reasons why this particular word struck such a controversial chord. I give an updated semantic perspective on the word altyerre , drawing on evidence from Arandic languages and from other languages in Central Australia. Then I examine some of the consequences of both religious and secular interpretations of altyerre and show how the popularisation of this word and its translations has impacted on its meanings in current usage.     

Neutralism and selectionism: a network-based reconciliation

Neutralism and selectionism are extremes of an explanatory spectrum for understanding patterns of molecular evolution and the emergence of evolutionary innovation. Although recent genome-scale data from protein-coding genes argue against neutralism, molecular engineering and protein evolution data argue that neutral mutations and mutational robustness are important for evolutionary innovation. Here I propose a reconciliation in which neutral mutations prepare the ground for later evolutionary adaptation. Key to this perspective is an explicit understanding of molecular phenotypes that has only become accessible in recent years.     

Disaffected black and white youth: The role of unemployment duration and perceived job discrimination*

While unauthorized immigration has existed in the USA since the inception of immigration laws in the early twentieth century, ‘illegality’ did not become a central concern in mainstream debate until the late 1970s. Existing scholarship has developed two lines of argument to explain the salience of illegality: a state-centred approach that sees bureaucrats pushing forth the category, and a ‘bottom-up’ approach that emphasizes the grass-roots activism of restrictionist organizations effectively disguising their nativism by appealing to law and order. The data collected here builds on but complicates the state-centred explanation, and points away from the ‘bottom-up’ approach. I locate a critical juncture in the immigration debate during the early 1970s and argue that the shift towards the focus on illegality as a point of concern was due to an alignment of interests that brought an array of civil society organizations commonly understood as progressive to coincide with sectors of the bureaucracy.
