Leading evolutionary theorists and philosophers come together to understand how organisms persist, even as they’re riddled with internal conflict, from cancer cells to selfish genes.

How does a vast menagerie of organs, tissues, cells, and genes coalesce to form a unified organism? For centuries, biologists and philosophers have taken this astonishing feat for granted, treating it as a matter of divine will or evolutionary inevitability. Yet unity is hardly assured. From cancer cells to selfish genes, the body is riven by internal conflicts.

The Paradox of the Organism grapples with this puzzle. As the essays in this collection show, profound questions arise when we pierce the organismal veil and consider the self-replicating elements within. Is an organism really a cohesive agent that adapts to the ecosystem it inhabits? Or is an organism itself an ecosystem, within which individual components are engaged in a continuous arms race?

The answers have immediate implications: for understanding miscarriage, treating cancer, improving psychological health, and preserving biodiversity. Challenging fundamental precepts of evolutionary theory, The Paradox of the Organism offers an incisive account of life’s extraordinary success.

Alfred V. Kidder’s excavations at Pecos Pueblo in New Mexico between 1914 and 1929 set a new standard for archaeological fieldwork and interpretation. Among his other innovations, Kidder recognized that skeletal remains were a valuable source of information, and today the Pecos sample is used in comparative studies of fossil hominins and recent populations alike.

In the 1990s, while documenting this historic collection in accordance with the Native American Graves Protection and Repatriation Act before the remains were returned to the Pueblo of Jemez and reinterred at Pecos Pueblo, Michèle E. Morgan and colleagues undertook a painstaking review of the field data to create a vastly improved database. The Peabody Museum, where the remains had been housed since the 1920s, also invited a team of experts to collaboratively study some of the materials.

In Pecos Pueblo Revisited, these scholars review some of the most significant findings from Pecos Pueblo in the context of current Southwestern archaeological and osteological perspectives and provide new interpretations of the behavior and biology of the inhabitants of the pueblo. The volume also presents improved data sets in extensive appendices that make the primary data available for future analysis. The volume answers many existing questions about the population of Pecos and other Rio Grande sites and will stimulate future analysis of this important collection.

Phylogeography is a discipline concerned with various relationships between gene genealogies—phylogenetics—and geography. The word “phylogeography” was coined in 1987, and since then the scientific literature has reflected an exploding interest in the topic. Yet, to date, no book-length treatment of this emerging field has appeared. Phylogeography: The History and Formation of Species fills that gap.

The study of phylogeography grew out of the observation that mitochondrial DNA lineages in natural populations often display distinct geographic orientations. In recent years, the field has expanded to include assessments of nuclear as well as cytoplasmic genomes and the relationships among gene trees, population demography, and organismal history, often formalized as coalescent theory. Phylogeography has connections to molecular evolutionary genetics, natural history, population biology, paleontology, historical geography, and speciation analysis.

Phylogeography captures the conceptual and empirical richness of the field, and also the sense of genuine innovation that phylogeographic perspectives have brought to evolutionary studies. This book will be essential reading for graduate students and professionals in evolutionary biology and ecology as well as for anyone interested in the emergence of this new and integrative discipline.

Representative of the international acclaim accorded Ernst Mayr’s Animal Species and Evolution, published in 1963, is Sir Julian Huxley’s description of it as “a magistral book…certainly the most important study of evolution that has appeared in many years—perhaps since the publication of On the Origin of Species.” In his extraordinary book, Mayr fully explored, synthesized, and evaluated man’s knowledge about the nature of animal species and the part they play in the process of evolution.

In this long-awaited abridged edition, Mayr’s definitive work is made available to the interested nonspecialist, the college student, and the general reader. The author has retained the dominant themes of his original study—themes now more widely accepted than they were in 1963: the species is the most important unit of evolution; individuals (and not genes) are the targets of natural selection, hence the fitness of “a” gene is a nebulous if not misleading concept; and the most important genetic phenomena in species are species-specific regulatory systems that give species internal cohesion.

Each of the twenty chapters of the original edition has been revised; six have been extensively reworked. Discussions of peripheral subjects and massive citations of the literature have been eliminated, but the glossary has been greatly expanded. The focal point of the volume is, naturally, the species—a reproductively isolated aggregate of interbreeding populations. Presenting an overview of evolutionary biology in Chapter 1, Mayr then considers the nature of species, their population structure, their biological interactions, the multiplication of species, and their role in evolution.

Because of the impossibility of experimenting with man and because an understanding of man’s biology is indispensable for safeguarding his future, emphasis throughout the book is placed on those findings from higher animals which are directly applicable to man. The last chapter, “Man as a Biological Species,” is of particular interest to the general reader. Mayr concludes that while modern man appears to be as well adapted for survival purposes as were his ancestors, there is much evidence to suggest that he is threatened by the loss of his most typically human characteristics.

In more ways than we may sometimes care to acknowledge, the human being is just another primate--it is certainly only very rarely that researchers into cognition, emotion, personality, and behavior in our species and in other primates come together to compare notes and share insights. This book, one of the few comprehensive attempts at integrating behavioral research into human and nonhuman primates, does precisely that--and in doing so, offers a clear, in-depth look at the mutually enlightening work being done in psychology and primatology.

Relying on theories of behavior derived from psychology rather than ecology or biological anthropology, the authors, internationally known experts in primatology and psychology, focus primarily on social processes in areas including aggression, conflict resolution, sexuality, attachment, parenting, social development and affiliation, cognitive development, social cognition, personality, emotions, vocal and nonvocal communication, cognitive neuroscience, and psychopathology. They show nonhuman primates to be far more complex, cognitively and emotionally, than was once supposed, with provocative implications for our understanding of supposedly unique human characteristics. Arguing that both human and nonhuman primates are distinctive for their wide range of context-sensitive behaviors, their work makes a powerful case for the future integration of human and primate behavioral research.

• Anthropogenic Connection Boxes. Humans are changing the planet. We are clearing forests, polluting the oceans, irrigating deserts, poisoning the soils, and driving a dramatic increase in global temperatures. All of these changes alter both the habitats where animals live and the species themselves as they evolve in response to our impact on their surroundings. Students will dig deep into how anthropogenic evolution affects animal behavior.
• Social Network Connection Boxes. Researchers have discovered that social networks play a critical role in almost every aspect of animal life: what they eat, how they protect themselves, who they mate with, the dynamics of parent-offspring relations, aggression, navigation, communication, play, cooperation, culture, and more. Students will discover how social network studies enrich our understanding of the wondrous complexity of animal behavior.

Examining the links between today’s ideas of radical life extension and age-old notions of immortality
 

From Plato’s notion of generation to Derrida’s concept of survival to such modern phenomena as anti-aging treatments, cryogenics, cloning, and whole-brain uploads, Adam Rosenthal’s Prosthetic Immortalities shows how the dream of indefinite life has always been a technological one: a matter of prosthesis. He argues that every biological instance of perpetual life, from one-celled organisms to rejuvenating jellyfish to Henrietta Lacks’s “immortal” cancer cells, always results in the transformation of the original being. There can, therefore, be no certainty of immortality. Yet, because finite mortal life is already marked by difference, division, and change, as Rosenthal concludes: “the problem of immortality will not cease to haunt us.”

Prosthetic Immortalities examines the persistence of humans’ aspirations of deathlessness, showing that the link between immortalization and prostheticization is not unique to a single period but is, rather, a ubiquitous element of the discourse of immortality, encompassing both modern technoscientific efforts and religious discourses of an afterlife. Rosenthal asks to what extent the emergence of a virtual, posited, immortal presence follows from the tenets of empirical science—and not simply from the discourse of biology but also, and more radically still, from biological organization itself.

Rosenthal ultimately argues that the discovery of biological immortals—lifeforms that naturally have indefinitely long lifespans, such as cancer cells and bacteria—present novel conceptual difficulties for traditional philosophical approaches to mortality and selfhood, asking whether it is life itself that first births immortalizing prostheses.
