“The Role of the Individual in Evolution” is a prescient yet neglected 1941 work by the 20th century’s most important paleontologist, George Gaylord Simpson. In a curious intermingling of explanation and critique, Simpson engages questions that would become increasingly fundamental in modern biological theory and philosophy. Did individuality, adaptation, and evolutionary causation reside at more than one level: the cell, the organism, the genetically coherent reproductive group, the social group, or some combination thereof? What was an individual, anyway? In this (...) introduction, we highlight two points in a wider historical context. First, recognizing the political context of Simpson’s writing profoundly deepens our understanding of the development of his science as the Modern Evolutionary Synthesis infused biology. Second, this story illuminates the emergence of debates around what would eventually come to be called multilevel selection theory. The organism-centered concept of biological individuality defended by Simpson is situated in relation to the then-emerging Synthesis, in which he was a renowned player, and also in relation to the views he opposed: the “metaphysical” ideas of paleontologists such as Henry Fairfield Osborn, who claimed that some evolutionary trends derived from potentialities already implanted in the germplasm; and the organicist ideas of Ralph W. Gerard and the Chicago School of ecologists, which he derided as all too congenial to totalitarianism. We find parallels between the ways that Simpson thought then about human individuality under totalitarianism and the way he thought about individuality in evolution; not that any causal relationship linked the two, but that commonalities of hierarchical structure exist between single entities and groups in both instances. We then trace the subsequent development of Simpson’s political and philosophical takes on the role of the individual in evolution through the 1960s and lightly sketch out the later fate of the organicist ideas of the Chicago School. Simpson’s paper, originally published in the Journal of the Washington Academy of Sciences, is available as supplementary material in the online version of this article, as part of the "Classics in Biological Theory" collection.

In an ironic rejoinder to the postmodern politics of nature, I will adopt an anthropological perspective on culture, which is conspicuous by its absence in the latest wave of science studies, and reformulate the distinction between nature and culture as a reflexive distinction within culture that emerges with modernity. In order to countering the hypertextualism of the constructivists, I will next sketch out a realist theory of nature. Combining the transcendental realism of Roy Bhaskar with the transcendental phenomenology of Edmund (...) Husserl, I will then try to outline the contours of a realist phenomenology of the ontological regions of physical, animal and human nature. Resuming my anthropological considerations on culture, I will finish the article with a progressive account of how the opposition between regional ontologies and regional typologies could be overcome.

Two protracted debates about the moral status of animals in ecological restoration projects are discussed that both testify to the troubling aspects of our inclination to think in terms of dualisms and dichotomies. These cases are more or less complementary: the first one is about the (re)introduction of species that were once pushed out of their native environment; the other one concerns the elimination or eradication of “exotic” and “alien” species that have invaded and degraded ecosystems. Both cases show the (...) detrimental impact of dualistic thinking on ecological restoration projects. In the first case, communication and cooperation between stakeholders is frustrated by the opposition of zoocentrism and ecocentrism; in the second case the opposition of nativism and cosmopolitanism appears to be a major stumbling block for consensus building and conflict management. I will argue that “gradualization”—thinking in terms of degrees instead of boundaries—can offer a way out of this black-and-white thinking and can open up space for negotiation and deliberation among different and sometimes diverging perspectives.
