The Vrolik ethnographical collection consisted of roughly 300 skulls, mummified heads, skeletons, pelvises, wet-preserved preparations, and plaster models, collected by Gerard Vrolik (1775–1859) and his son Willem (1801–1863). Most prominent in this collection were the skulls, of which 177 remain in the collection of present-day Museum Vrolik. These skulls—a troubling heritage of colonialism and scientific racism—are the central subjects of this paper, which considers the changing meanings and values of these skulls for racial science over approximately 160 years, between ± (...) 1800 and 1960. These shifting meanings are analysed using the skulls themselves as primary sources, including the labels, numbers and handwriting present on them or their stands. Central topics addressed will be matters of classification, hierarchy, scientific bias, and disciplinary development of racial anthropology from the study and collection of idealized national types to a quantitative craniometry of populations. This paper demonstrates that during 160 years of study of this same set of crania, the skulls of white European origin gradually lost racial relevance and were increasingly normalized, whereas the skulls of dark-skinned people of African descent continued to be categorized in a typological racial scheme and as such were increasingly othered.

Theodosius Dobzhansky was one of the principal ‘founding fathers' of the modern ‘synthetic theory of evolution' and the ‘biological species' concept, first set forth in his classic book, Genetics and the Origin of Species (1937). Much of the discussion of Dobzhansky’s work by historians has focused on English-accessible sources, and has emphasized the roles of the Morgan School, and figures such as Sewall Wright, and Leslie C. Dunn. This article uses Dobzhansky’s Russian articles that are unknown to English-speaking readers, and (...) his late 1920s to early 1930s correspondence with colleagues and friends in the Soviet Union, to clarify some of the Russian influences on Dobzhansky’s evolving evolutionary views, particularly the development of his views on species and speciation. For Dobzhansky, as for Darwin, the problem of species and speciation was crucial for his theoretical explanation of evolution. (shrink)

Focusing on the relationship between two important scientists in the development of ecological thought during the first half of the twentieth century, this paper argues that Yale limnologist G. E. Hutchinson's adoption of the biogeochemical approach in the late 1930s builds on the 1920s work of the Russian scientist V. I. Vernadsky. An analysis of Hutchinson’s scientific publications shows that he first referred to Vernadsky in 1940, on two different occasions. This article analyzes the dynamics of Hutchinson’s formulation of the (...) biogeochemical approach, providing historical context and linking its early application to the existing limnological tradition.

When the sociobiology debate erupted in 1975, there were almost too many contributions to the heated exchanges between sociobiologists and their critics to count. In the fall of 1976, a Canadian educational film entitled _Sociobiology: Doing What Comes Naturally_ sparked further controversy due to its graphic visuals and outrageous narration. While critics claimed the film was a promotional tool to further the sociobiological agenda in educational settings, sociobiologists quickly distanced themselves from the film and, in turn, accused the critics of (...) consciously misrepresenting sociobiology by organizing showings of the film. Using audio, video, archival, and published sources, this paper explores the complicated history of _Sociobiology: Doing What Comes Naturally_ and demonstrates how the public debate about the film reflects the positions, polemics, and polarization of the sociobiology debate as a whole.

This paper examines the contributions of Daniel S. Lehrman (1919–1972) to animal behavior studies. Though widely cited as a critic of the early ethological program presented by Konrad Lorenz and Niko Tinbergen, other significant aspects of Lehrman’s career and research have not received historical attention. In this paper, I offer a fuller account of Lehrman’s work by situating his debate with ethologists within the larger context of Lehrman’s early scholarly development under G. K. Noble and T. C. Schneirla, by examining (...) his scientific research on the ring-dove as well as his epistemological views about the best way to understand animal behaviour, and by presenting his leadership in institution and network-building of interdisciplinary approaches to animal behavior. This essay highlights Lehrman’s impact on the evolution of ethology, endocrinology, and developmental biology. (shrink)

I argue that the French sociologist Émile Durkheim (1858–1917) decided to constitute sociology, a novel field, as ‘scientific’ early in his career. He adopted evolutionized biology as then practiced as his principal model of science, but at first wavered between alternative repertoires of concepts, models, metaphors and analogies, in particular Spencerian Lamarckism and French neo-Lamarckism. I show how Durkheim came to fashion a particular deployment of the French neo-Lamarckian repertoire. The paper describes and analyzes this repertoire and explicates how it (...) might have been available to a non-biologist. I analyze Durkheim’s very early writings between 1882 and 1892 in this context to substantiate my argument. (shrink)

Beginning in the nineteenth century, scientists speculated that the Pleistocene megafauna—species such as the giant ground sloth, wooly mammoth, and saber-tooth cat—perished because of rapid climate change accompanying the end of the most recent Ice Age. In the 1950s, a small network of ecologists challenged this view in collaboration with archeologists who used the new tool of radiocarbon dating. The Pleistocene overkill hypothesis imagined human hunting, not climate change, to be the primary cause of megafaunal extinction. This article situates the (...) Pleistocene overkill hypothesis in a broader history of the emergence of historical ecology as a distinct sub-discipline of paleoecology. Tracing the work of the Yale Geochronometric Laboratory and an interdisciplinary research network that included Paul Sears, Richard Foster Flint, Edward Deevey, Kathryn Clisby, and Paul S. Martin, it reveals how both the methods and the meaning of studying fossil pollen shifted between the 1910s and 1960s. First used as a tool for fossil fuel extraction, fossil pollen became a means of envisioning climatic history, and ultimately, a means of reimagining global ecological history. First through pollen stratigraphy and then through radiocarbon dating, ecologists reconstructed past biotic communities and rethought the role of humans in these communities. By the 1980s, the discipline of historical ecology would reshape physical environments through the practice of ecological restoration. (shrink)

Alexander von Humboldt’s depictions of mountain vegetation are among the most iconic nineteenth century illustrations in the biological sciences. Here we analyse the contemporary context and empirical data for all these depictions, namely the _Tableau physique des Andes_ (1803, 1807), the _Geographiae plantarum lineamenta_ (1815), the _Tableau physique des Îles Canaries_ (1817), and the _Esquisse de la Géographie des plantes dans les Andes de Quito_ (1824/1825). We show that the Tableau physique des Andes does not reflect Humboldt and Bonpland’s field (...) data and presents a flawed depiction of plant occurrences and vertical succession of vegetation belts, arising from Humboldt’s misreading of La Condamine’s description (1751). Humboldt's 1815 depiction, by contrast, shows a distribution of high-vegetation belts that is consistent with La Condamine’s description, while the 1824 depiction drops innovations made in 1815 and returns to simply showing numerous species’ names, thus not applying Humboldt’s own earlier zonation framework. Our analysis of contemporary reactions to Humboldt’s TPA includes Francis Hall’s posthumously published 1834 illustration of Andean plant zonation near Quito and Humboldt’s reaction to Hall’s critique. Throughout his work on plant geography, Humboldt disregarded some of his own observations, or confused them. At stake was his reputation as an innovator in the field of plant geography and a discoverer of the sequence of high-elevation vegetation belts on the world’s mountains. (shrink)

Jean-Baptiste Lamarck is well known as a pre-Darwinian proponent of evolution. But much of what has been written on Lamarck, on his ‘Lamarckian’ belief in the inheritance of acquired characters, and on his conception of the role of the will in biological development mischaracterizes his views. Indeed, surprisingly little in-depth analysis has been published regarding his views on human physiology and development. Further, although since Robert M. Young’s signal 1969 essay on Malthus and the evolutionists, Darwin scholars have sought to (...) place Darwin’s work in its social and political context, this has yet to be done adequately for Lamarck. Here I address this gap. I argue that the will was of particular importance to Lamarck’s social commentary and his hopes for the transformation of the French people and nation. Further, I argue that if we are to really grasp Lamarck’s ideas and intentions we need to contextualize his works in relation to prevailing debates in France about the physiology of mind and morals and the future of the nation.

The idea that the brain is a representational organ has roots in the nineteenth century, when neurologists began drawing conclusions about what the brain represents from clinical and experimental studies. One of the earliest controversies surrounding representation in the brain was the “muscles versus movements” debate, which concerned whether the motor cortex represents complex movements or rather fractional components of movement. Prominent thinkers weighed in on each side: neurologists John Hughlings Jackson and F.M.R. Walshe in favor of complex movements, neurophysiologist (...) Charles Sherrington and neurosurgeon Wilder Penfield in favor of movement components. This essay examines these and other brain scientists’ evolving notions of representation during the first eighty years of the muscles versus movements debate (c. 1873–1954). Although participants agreed about many of the superficial features of representation, their inferences reveal deep-seated disagreements about its inferential role. Divergent epistemological commitments stoked conflicting conceptions of what representational attributions imply and what evidence supports them. (shrink)

The essay offers a close reading of the inaugural address _Termite Craze_ by the entomologist Karl Escherich, the first German university president to be appointed by the Nazis. Faced with a divided audience and under pressure to politically align the university, Escherich, a former member of the NSDAP, discusses how and to what extent the new regime can recreate the egalitarian perfection and sacrificial predisposition of a termite colony. The paper pays particular attention to the ways in which Escherich tries (...) to appease the various factions in his audience (faculty, students and the Nazi party); in doing so, it also discusses how Escherich depicts his address in the altered versions of his later memoirs.
