Individuals are things that everybody knows – or thinks they do. Yet even scholars who practice or analyze the biological sciences often cannot agree on what an individual is and why. One reason for this disagreement is that the many important biological individuality concepts serve very different purposes – defining, classifying, or explaining living structure, function, interaction, persistence, or evolution. Indeed, as the contributors to Biological Individuality reveal, nature is too messy for simple definitions of this concept, organisms too quirky in the diverse ways they reproduce, function, and interact, and human ideas about individuality too fraught with philosophical and historical meaning.
Bringing together biologists, historians, and philosophers, Biological Individuality provides a multifaceted exploration of biological individuality that identifies leading and less familiar perceptions of individuality both past and present, what they are good for, and in what contexts. Biological practice and theory recognize individuals at myriad levels of organization, from genes to organisms to symbiotic systems. We depend on these notions of individuality to address theoretical questions about multilevel natural selection and Darwinian fitness; to illuminate empirical questions about development, function, and ecology; to ground philosophical questions about the nature of organisms and causation; and to probe historical and cultural circumstances that resonate with parallel questions about the nature of society. Charting an interdisciplinary research agenda that broadens the frameworks in which biological individuality is discussed, Biological Individuality makes clear that in the realm of the individual, there is not and should not be a direct path from biological paradigms based on model organisms through to philosophical generalization and historical reification.

"Individuality is one of the hottest topics in the philosophy of biology today. The recent, technologically driven explosion of knowledge about the microbial world has led both biologists and philosophers to reconsider the traditional idea that organisms are genetically uniform populations of cells with a clear physical boundary – bodies. Very up-to-date, containing a number of substantial original contributions, and with a good balance of historians, philosophers, and eminent scientists, Biological Individuality is well positioned to represent the most exciting strands of the current debate."
– Paul Griffiths, University of Sydney, coauthor of Genetics and Philosophy: An Introduction
"A tour de force inquiry of individuality that proposes a fruitful perspective that potentially resolves many of its disparate definitions. Biological Individuality reflects the strengths of cross-disciplinary research on fundamental biological concepts."
