The relationship of man himself to his environment is an inseparable part of ecology; for he also is an organism and other organisms are a part of his environment. Ecology, therefore, broadly conceived and rightly understood, instead of being an academic science merely, out of touch with humanistic interests, is really that part of every other biological science which brings it into immediate relation to human kind. The proper place of humans in ecological study has been a recurring issue for (...) ecology. Of course humans are part of Nature writ large, but are they part of the ecologist's nature? The question bothered biologists even before the discipline of ecology was firmly institutionalized.... (shrink)

ABSTRACT This essay presents an alternative to interpretations of laboratories as institutions for controlled investigation of nature that are either placeless or “set apart.” It historicizes the claim by showing how the meaning of “laboratory” has both changed and diversified over the last two centuries. Originally a laboratory could be a site of organic growth or material manufacture, but it can now be a specialized domain for technological development, educational training, or quality testing. The essay then introduces some contingencies of (...) geography and gender by showing how boundaries between laboratories and other spaces—especially domestic kitchens—could be permeable or nonexistent; importantly, some spaces served as experimental laboratories without ever being designated as such. A key corollary, however, is that there were limits to this permeability: not all social spaces could be turned consensually into laboratories, and laboratory users could be intolerant of certain imported technical cultures.

Anton de Bary is best known for his elucidation of the life cycle of Phytopthora infestans, the causal organism of late blight of potato and the crop losses that caused famine in nineteenth-century Europe. But while practitioner histories often claim this accomplishment as a founding moment of modern plant pathology, closer examination of de Bary’s experiments and his published work suggest that his primary motiviation for pursing this research was based in developmental biology, not agriculture. De Bary shied away from (...) making any recommendations for agricultural practice, and instead focused nearly exclusively on spontaneous generation and fungal development – both concepts promoted through prize questions posted by the Académie des Sciences in the 1850s and 1860s. De Bary’s submission to the Académie’s 1859 Alhumbert prize question illustrates his own contributions to debates about spontaneous generation and demonstrates the practical applications of seemingly philosophical questions – such as the origin of life.

Much has happened in the Darwin field since the _Correspondence_ began publishing in 1985. This overview of historiography suggests that the richness of the letters generates fresh scholarly questions and that Darwin, paradoxically, is becoming progressively deconstructed as a key figure in the history of science.

Our paper aims at bringing to the fore the crucial role that habits play in Charles Darwin’s theory of evolution by means of natural selection. We have organized the paper in two steps: first, we analyse value and functions of the concept of habit in Darwin's early works, notably in his Notebooks, and compare these views to his mature understanding of the concept in the Origin of Species and later works; second, we discuss Darwin’s ideas on habits in the light (...) of today’s theories of epigenetic inheritance, which describe the way in which the functioning and expression of genes is modified by the environment, and how these modifications are transmitted over generations. We argue that Darwin’s lasting and multifaceted interest in the notion of habit, throughout his intellectual life, is both conceptually and methodologically relevant. From a conceptual point of view, intriguing similarities can be found between Darwin’s (early) conception of habit and contemporary views on epigenetic inheritance. From a methodological point of view, we suggest that Darwin’s plastic approach to habits, from his early writings up to the mature works, can provide today’s evolutionary scientists with a viable methodological model to address the challenging task of extending and expanding evolutionary theory, with particular reference to the integration of epigenetic mechanisms into existing models of evolutionary change. Over his entire life Darwin has modified and reassessed his views on habits as many times as required by evidence: his work on this notion may represent the paradigm of a habit of good scientific research methodology.

The history of twentieth-century life sciences is not exactly a new topic. However, in view of the increasingly rapid development of the life sciences themselves over the past decades, some of the well-established narratives are worth revisiting. Taking stock of where we stand on these issues was the aim of a conference in 2015, entitled “Perspectives for the History of Life Sciences”. The papers in this topical collection are based on work presented and discussed at and around this meeting. Just (...) as the conference, the collection aims at exploring fields in the history of life sciences that appear understudied, sources that have been overlooked, and novel ways of engaging with this material. The papers convened in this collection may not be representative of the field as a whole; but we feel that they do indicate some elements that have received emphasis in recent years, and may become more central in the years to come, such as the history of previously neglected contexts and domains of the life sciences, the question of continuity and change on the level of practices, the history of complexity and diversity in twentieth-century life sciences and the reconsideration of the relationship between history and philosophy of life sciences.

The paper uses the example of historical paper research in Vienna around 1900 in order to analyze the dynamics of scientific cooperation between the natural sciences and the humanities. It focuses on the Vienna-based plant physiologist Julius Wiesner (1838–1916), who from 1884 to 1911 studied medieval paper manuscripts under the microscope in productive cooperation with paleographers, archaeologists and orientalists (Josef Karabacek, Marc Aurel Stein, Rudolf Hoernle). The paper examines why these cooperations succeeded and how they developed over time. Here we (...) distinguish between two forms of cooperation: while Wiesner initially worked only reactively, in a “closed cooperation”, he later entered into “open cooperations”, in which both parties defined research questions and methods. This form of cooperation proved particularly successful, but at the same time was especially demanding because, in addition to contributing one’s own skills, it required considerable “interlocking expertise” (Andersen 2016). This was favored because the historical auxiliary sciences were in a phase of upheaval. Wiesner contributed his knowledge of technical microscopy and developed a genuine interest in historical questions, while the humanists were prepared to open themselves to scientific processes and ultimately acknowledged Wiesner as a historian of paper in his own right.

ZusammenfassungDie Studie analysiert die Dynamik wissenschaftlicher Kooperation zwischen Natur- und Geisteswissenschaften an einem Beispiel aus der historischen Papierforschung in Wien um 1900. Im Mittelpunkt steht der Wiener Pflanzenphysiologe Julius Wiesner (1838–1916), der ab 1884 (und bis 1911) mittelalterliche Papiermanuskripte unter dem Mikroskop prüfte. Dies erfolgte in produktiver Zusammenarbeit mit Paläographen, Archäologen und Orientalisten (Josef Karabacek, Marc Aurel Stein, Rudolf Hoernle). Der Aufsatz untersucht, warum dies gelang und wie die Zusammenarbeit sich entwickelte. Wir unterscheiden dabei zwei Formen der Kooperation: Während Wiesner (...) anfangs nur reaktiv zuarbeitete, in einer „geschlossenen Kooperation“, trat er später in „offene Kooperationen“ ein, in der beide Parteien die Fragen definieren und geeignete Methoden entwickeln. Diese Form der Kooperation erwies sich als besonders erfolgreich – zugleich war sie besonders anspruchsvoll, denn neben fachlicher Expertise erforderte sie erhebliche „Integrationsexpertise“ (Andersen 2016). Dies wurde begünstigt durch die lokale Konstellation in einer Umbruchphase der historischen Hilfswissenschaften. Wiesner konnte seine Kenntnisse der technischen Mikroskopie einbringen und gewann ein genuines Interesse an den historischen Fragen, während die Geisteswissenschaftler bereit waren, sich naturwissenschaftlichen Verfahren gegenüber zu öffnen und Wiesner letztlich als Papierhistoriker eigenen Rechts anzuerkennen.

In the early years of Mendelism, 1900-1910, William Bateson established a productive research group consisting of women and men studying biology at Cambridge. The empirical evidence they provided through investigating the patterns of hereditary in many different species helped confirm the validity of the Mendelian laws of heredity. What has not previously been well recognized is that owing to the lack of sufficient institutional support, the group primarily relied on domestic resources to carry out their work. Members of the group (...) formed a kind of extended family unit, centered on the Batesons' home in Grantchester and the grounds of Newnham College. This case illustrates the continuing role that domestic environments played in supporting scientific research in the early 20th century. (shrink)

Inheritance and variation were a major focus of Charles Darwin’s studies. Small inherited variations were at the core of his theory of organic evolution by means of natural selection. He put forward a developmental theory of heredity (pangenesis) based on the assumption of the existence of material hereditary particles. However, unlike his proposition of natural selection as a new mechanism for evolutionary change, Darwin’s highly speculative and contradictory hypotheses on heredity were unfruitful for further research. They attempted to explain many (...) complex biological phenomena at the same time, disregarded the then modern developments in cell theory, and were, moreover, faithful to the widespread conceptions of blending and so-called Lamarckian inheritance. In contrast, Mendel’s approaches, despite the fact that features of his ideas were later not found to be tenable, proved successful as the basis for the development of modern genetics. Mendel took the study of the transmission of traits and its causes (genetics) out of natural history; by reducing complexity to simple particulate models, he transformed it into a scientific field of research. His scientific approach and concept of discrete elements (which later gave rise to the notion of discrete genes) also contributed crucially to the explanation of the existence of stable variations as the basis for natural selection.

After Darwin, experimental biology sought to unravel organisms. By the early twentieth century, organisms were broadly conceived as the product of their heredity and their environment. Much historical work has explored the scientific attack on the genotype, particularly through the new science of genetics. This article explores the tandem efforts to assert experimental control over the environment in which plants grew and developed. The case described here concerns the creation of the first phytotron at Caltech by botanist and plant physiologist (...) Frits Went. Opening in 1949, the phytotron was a plant laboratory that, across a series of rooms and chambers, kept genes constant while regulating and maintaining defined ranges of known environments. This article details the context in which the phytotron emerged, how the phytotron gained its sobriquet, and how it served to cement the “environment” as a category of biological knowledge. Describing the institutional context of Caltech, its interdisciplinary culture, and its encouragement of adopting technology into biological science, I argue that the phytotron and the commensurate category of the “environment” were the product of the familiar movement to integrate the physical and biological sciences. In addition, however, the creation of the phytotron was also a broader story of plant physiologists establishing a definition of the “environment” in both physical and technological terms. (shrink)
