Animal Body Size
Linking Pattern and Process across Space, Time, and Taxonomic Group
Edited by Felisa A. Smith and S. Kathleen Lyons
University of Chicago Press, 2013
Galileo wrote that “nature cannot produce a horse as large as twenty ordinary horses or a giant ten times taller than an ordinary man unless by miracle or by greatly altering the proportions of his limbs and especially of his bones”—a statement that wonderfully captures a long-standing scientific fascination with body size. Why are organisms the size that they are? And what determines their optimum size?          
           
This volume explores animal body size from a macroecological perspective, examining species, populations, and other large groups of animals in order to uncover the patterns and causal mechanisms of body size throughout time and across the globe. The chapters represent diverse scientific perspectives and are divided into two sections. The first includes chapters on insects, snails, birds, bats, and terrestrial mammals and discusses the body size patterns of these various organisms. The second examines some of the factors behind, and consequences of, body size patterns and includes chapters on community assembly, body mass distribution, life history, and the influence of flight on body size.

Biological Individuality
Integrating Scientific, Philosophical, and Historical Perspectives
Edited by Scott Lidgard and Lynn K. Nyhart
University of Chicago Press, 2017
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, this book 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, this book 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.

Ghost Stories for Darwin
The Science of Variation and the Politics of Diversity
Banu Subramaniam
University of Illinois Press, 2014
In a stimulating interchange between feminist studies and biology, Banu Subramaniam explores how her dissertation on flower color variation in morning glories launched her on an intellectual odyssey that engaged the feminist studies of sciences in the experimental practices of science by tracing the central and critical idea of variation in biology.

Subramaniam reveals the histories of eugenics and genetics and their impact on the metaphorical understandings of difference and diversity that permeate common understandings of differences among people exist in contexts that seem distant from the so-called objective hard sciences. Journeying into interdisciplinary areas that range from the social history of plants to speculative fiction, Subramaniam uncovers key relationships between the life sciences, women's studies, evolutionary and invasive biology, and the history of ecology, and how ideas of diversity and difference emerged and persist in each field.

The Struggle of Parts
Wilhelm Roux
Harvard University Press, 2024

A landmark work of nineteenth-century developmental and evolutionary biology that takes the Darwinian struggle for existence into the organism itself.

Though he is remembered primarily as a pioneer of experimental embryology, Wilhelm Roux was also a groundbreaking evolutionary theorist. Years before his research on chicken and frog embryos cemented his legacy as an experimentalist, Roux endorsed the radical idea that a “struggle for existence” within organisms—between organs, tissues, cells, and even subcellular components—drives individual development.

Convinced that external competition between individuals is inadequate to explain the exquisite functionality of bodily parts, Roux aimed to uncover the mechanistic principles underlying self-organization. The Struggle of Parts was his attempt to provide such a theory. Combining elements of Darwinian selection and Lamarckian inheritance of acquired characteristics, the work advanced a materialist explanation of how “purposiveness” within the organism arises as the body’s components compete for space and nourishment. The result, according to Charles Darwin, was “the most important book on evolution which has appeared for some time.”

Translated into English for the first time by evolutionary biologist David Haig and Richard Bondi, The Struggle of Parts represents an important forgotten chapter in the history of developmental and evolutionary theory.

Variation, Senescence, and Neoplasia in Cultured Somatic Cells
John W. Littlefield
Harvard University Press, 1976

Aging and cancer may be manifestations of genetic, or epigenetic, changes in somatic cells. Through research, laboratory analysis of these related processes has become possible. Cells can be removed from the body, kept warm in laboratory glassware, nourished by artificial solutions, and studied for years, or even decades. Two types of cultures have emerged: Primary cultures, grown from cells obtained directly from living animals, may grow well for generations, but ultimately cease to divide. Established cultures, on the other hand, may grow and divide indefinitely. It is a striking fact that most, if not all, established cultures consist of cells that are heteroploid, having an abnormal chromosome complement that may include structural rearrangements as well as abnormalities of chromosome number.

Most established cultures are also neoplastic on behavior and morphology—in this, they resemble cancers—and established cultures are, in fact, often grown from cancer cells. Interest in the role of chromosomes in neoplasia has recently been overshadowed by an emphasis on tumor viruses. This book should reawaken the former interest. It will also arouse new interest in the role of epigenetic mechanisms of animal cells, in contrast to the classic genetic processes. As Dr. John Littlefield writes: “The relationship between the overcoming of senescence, the appearance of heteroploidy, and the acquisition of neoplastic qualities is not yet clear, but it is of such great theoretical and practical importance as to demand attention and new ideas.”
