    Naturalists, Molecular Biologists, and the Challenges of Molecular Evolution.Joel B. Hagen - 1999 - Journal of the History of Biology 32 (2):321 - 341.
    Biologists and historians often present natural history and molecular biology as distinct, perhaps conflicting, fields in biological research. Such accounts, although supported by abundant evidence, overlook important areas of overlap between these areas. Focusing upon examples drawn particularly from systematics and molecular evolution, I argue that naturalists and molecular biologists often share questions, methods, and forms of explanation. Acknowledging these interdisciplinary efforts provides a more balanced account of the development of biology during the post-World War II era.

    Experimentalists and naturalists in twentieth-century botany: Experimental taxonomy, 1920?1950.Joel B. Hagen - 1984 - Journal of the History of Biology 17 (2):249-270.
    Experimental taxonomy was a diverse area of research, and botanists who helped develop it were motivated by a variety of concerns. While experimental taxonomy was never totally a taxonomic enterprise, improvement in classification was certainly one major motivation behind the research. Hall's and Clements' belief that experimental methods added more objectivity to classification was almost universally accepted by experimental taxonomists. Such methods did add a new dimension to taxonomy — a dimension that field and herbarium studies, however rigorous, could not (...)

    The diving reflex and asphyxia: working across species in physiological ecology.Joel B. Hagen - 2018 - History and Philosophy of the Life Sciences 40 (1):18.
    Beginning in the mid-1930s the comparative physiologists Laurence Irving and Per Fredrik Scholander pioneered the study of diving mammals, particularly harbor seals. Although resting on earlier work dating back to the late nineteenth century, their research was distinctive in several ways. In contrast to medically oriented physiology, the approaches of Irving and Scholander were strongly influenced by natural history, zoology, ecology, and evolutionary biology. Diving mammals, they argued, shared the cardiopulmonary physiology of terrestrial mammals, but evolution had modified these basic (...)

    Research perspectives and the anomalous status of modern ecology.Joel B. Hagen - 1989 - Biology and Philosophy 4 (4):433-455.
    Ecology has often been characterized as an immature scientific discipline. This paper explores some of the sources of this alleged immaturity. I argue that the perception of immaturity results primarily from the fact that historically ecologists have based their work upon two very different approaches to research.

    Camels, Cormorants, and Kangaroo Rats: Integration and Synthesis in Organismal Biology After World War II.Joel B. Hagen - 2015 - Journal of the History of Biology 48 (2):169-199.
    During the decades following World War II diverse groups of American biologists established a variety of distinctive approaches to organismal biology. Rhetorically, organismal biology could be used defensively to distinguish established research traditions from perceived threats from newly emerging fields such as molecular biology. But, organismal biologists were also interested in integrating biological disciplines and using a focus on organisms to synthesize levels of organization from molecules and cells to populations and communities. Part of this broad movement was the development (...)

    Bergmann’s Rule, Adaptation, and Thermoregulation in Arctic Animals: Conflicting Perspectives from Physiology, Evolutionary Biology, and Physical Anthropology After World War II.Joel B. Hagen - 2017 - Journal of the History of Biology 50 (2):235-265.
    Bergmann’s rule and Allen’s rule played important roles in mid-twentieth century discussions of adaptation, variation, and geographical distribution. Although inherited from the nineteenth-century natural history tradition these rules gained significance during the consolidation of the modern synthesis as evolutionary theorists focused attention on populations as units of evolution. For systematists, the rules provided a compelling rationale for identifying geographical races or subspecies, a function that was also picked up by some physical anthropologists. More generally, the rules provided strong evidence for (...)

    Ecologists and taxonomists: Divergent traditions in twentieth-century plant geography.Joel B. Hagen - 1986 - Journal of the History of Biology 19 (2):197-214.
    The distinction between taxonomic plant geography and ecological plant geography was never absolute: it would be historically inaccurate to portray them as totally divergent. Taxonomists occasionally borrowed ecological concepts, and ecologists never completely repudiated taxonomy. Indeed, some botanists pursued the two types of geographic study. The American taxonomist Henry Allan Gleason (1882–1975), for one, made noteworthy contributions to both. Most of Gleason's research appeared in short articles, however. He never published a major synthetic work comparable in scope or influence to (...)

    Problems in the Institutionalization of Tropical Biology: The Case of the Barro Colorado Island Biological Laboratory.Joel B. Hagen - 1990 - History and Philosophy of the Life Sciences 12 (2):225 - 247.
    This article examines the changing status of tropical biology by considering the origins and early development of the Barro Colorado Island Biological Laboratory. Today the laboratory is part of a large diversified tropical research center operated by the Smithsonian Institution. However, for most of its history the laboratory led a tenuous existence. Both the early problems and eventual success of the institution can only be explained by considering the interaction of various intellectual, institutional, and broader social factors.

    Waiting for Sequences: Morris Goodman, Immunodiffusion Experiments, and the Origins of Molecular Anthropology. [REVIEW]Joel B. Hagen - 2010 - Journal of the History of Biology 43 (4):697 - 725.
    During the early 1960s, Morris Goodman used a variety of immunological tests to demonstrate the very close genetic relationships among humans, chimpanzees, and gorillas. Molecular anthropologists often point to this early research as a critical step in establishing their new specialty. Based on his molecular results, Goodman challenged the widely accepted taxonomie classification that separated humans from chimpanzees and gorillas in two separate families. His claim that chimpanzees and gorillas should join humans in family Hominidae sparked a well-known conflict with (...)

  17. Retelling Experiments: H. B. D. Kettlewell’s Studies of Industrial Melanism in Peppered Moths. [REVIEW]Joel B. Hagen - 1999 - Biology and Philosophy 14 (1):39-54.
    H. B. D. Kettlewell's field experiments on industrial melanism in the peppered moth, Biston betularia, have become the best known demonstration of natural selection in action. I argue that textbook accounts routinely portray this research as an example of controlled experimentation, even though this is historically misleading. I examine how idealized accounts of Kettlewell's research have been used by professional biologists and biology teachers. I also respond to some criticisms of David Rudge to my earlier discussions of this case study, (...)
