Historians have long assumed that new industrial machines and power sources eliminated work animals from nineteenth-century America, yet a bird's-eye view of nineteenth-century society would show millions of horses supplying the energy necessary for industrial development. Horses were ubiquitous in cities and on farms, providing power for transportation, construction, manufacturing, and agriculture. On Civil War battlefields, thousands of horses labored and died for the Union and the Confederacy hauling wagons and mechanized weaponry. The innovations that brought machinery to the forefront of American society made horses the prime movers of these machines for most of the nineteenth century. Mechanization actually increased the need for horsepower by expanding the range of tasks requiring it. Indeed, the single most significant energy transition of the antebellum era may have been the dramatic expansion in the use of living, breathing horses as a power technology in the development of industrial America. Ann Greene argues for recognition of horses' critical contribution to the history of American energy and the rise of American industrial power, and a new understanding of the reasons for their replacement as prime movers. Rather than a result of \"inevitable\" technological change, it was Americans' social and political choices about power consumption that sealed this animal's fate. The rise and fall of the workhorse was defined by the kinds of choices that Americans made and would continue to make—choices that emphasized individual mobility and autonomy, and assumed, above all, abundant energy resources.

How the lives and labors of nineteenth-century circus elephants shaped the entertainment industry. Consider the career of an enduring if controversial icon of American entertainment: the genial circus elephant. In Entertaining Elephants Susan Nance examines elephant behavior—drawing on the scientific literature of animal cognition, learning, and communications—to offer a study of elephants as actors (rather than objects) in American circus entertainment between 1800 and 1940. By developing a deeper understanding of animal behavior, Nance asserts, we can more fully explain the common history of all species. Entertaining Elephants is the first account that uses research on animal welfare, health, and cognition to interpret the historical record, examining how both circus people and elephants struggled behind the scenes to meet the profit necessities of the entertainment business. The book does not claim that elephants understood, endorsed, or resisted the world of show business as a human cultural or business practice, but it does speak of elephants rejecting the conditions of their experience. They lived in a kind of parallel reality in the circus, one that was defined by their interactions with people, other elephants, horses, bull hooks, hay, and the weather. Nance's study informs and complicates contemporary debates over human interactions with animals in entertainment and beyond, questioning the idea of human control over animals and people's claims to speak for them. As sentient beings, these elephants exercised agency, but they had no way of understanding the human cultures that created their captivity, and they obviously had no claim on (human) social and political power. They often lived lives of apparent desperation.

The concept of the 3Rs (Refinement, Reduction and Replacement) has been used as a framework for improving the welfare of laboratory animals for the last half century. By establishing an animal-centric view on housing and management, this book takes Russell and Burch’s definition of Refinement as “elimination of inhumanities” and goes further. Rather than fitting animals into experimental conditions, it encourages readers to adjust conditions to better meet the behavioral, emotional, physical, and physiological needs and preferences of the animals. The team of expert authors, from the fields of laboratory animal science, ethology, biology as well as animal training, provide ideas for creating housing conditions and handling procedures that induce, to the best of current abilities and knowledge, a long-term positive state of mind in the animals under our care. This book is written for animal caretakers, animal health technicians, researchers, animal facility managers, laboratory animal veterinarians, or anyone who engages in work with living experimental animals or is interested in the continuous improvement of laboratory animal welfare. This interdisciplinary guide will act as a catalyst, resulting in multiple viewpoints and fields collaborating to optimize laboratory animal welfare.

This book presents a history of animal rights. It brings a novel, sociological perspective to an area that has been addressed largely from a philosophical perspective, or from the entrenched positions of highly committed advocates of a particular position in the debate. This book is about the people who would speak for animals in laboratories. On the one hand, people vie to speak on animals' behalf in the policy arena, to advocate for them in a forum in which they have no direct voice. Animal protectionists are immediately obvious in this role, but so are veterinarians, other animal care professionals, and many scientists. On the other hand, speaking for animals means interpreting them, translating their animal minds into human language; it's a claim of expertise and knowledge rather than commitment and advocacy. But the two are intimately intertwined, and many of the policy debates examined in this book are about these two ways of speaking for animals. This book is offered to those who are hoping for some sort of balance that promotes animal welfare and biomedical progress, not platitudes or irrelevant rules with no real impact in animals' lives.

What was the life of a cow in early modern England like? What would it be like to milk that same cow, day-in, day-out, for over a decade? How did people feel about and toward the animals that they worked with, tended, and often killed? With these questions, Erica Fudge begins her investigation into a lost aspect of early modern life: the importance of the day-to-day relationships between humans and the animals with whom they worked. Such animals are and always have been, Fudge reminds us, more than simply stock; they are sentient beings with whom one must negotiate. It is the nature, meaning, and value of these negotiations that this study attempts to recover. By focusing on interactions between people and their livestock,Quick Cattle and Dying Wishesrestores animals to the central place they once had in the domestic worlds of early modern England. In addition, the book uses human relationships with animals-as revealed through agricultural manuals, literary sources, and a unique dataset of over four thousand wills-to rethink what quick cattle meant to a predominantly rural population and how relationships with them changed as more and more people moved to the city. Offering a fuller understanding of both human and animal life in this period, Fudge innovatively expands the scope of early modern studies and how we think about the role that animals played in past cultures more broadly.

Animals and Medicine: The Contribution of Animal Experiments to the Control of Disease offers a detailed, scholarly historical review of the critical role animal experiments have played in advancing medical knowledge. Laboratory animals have been essential to this progress, and the knowledge gained has saved countless lives—both human and animal. Unfortunately, those opposed to using animals in research have often employed doctored evidence to suggest that the practice has impeded medical progress. This volume presents the articles Jack Botting wrote for the Research Defence Society News from 1991 to 1996, papers which provided scientists with the information needed to rebut such claims. Collected, they can now reach a wider readership interested in understanding the part of animal experiments in the history of medicine—from the discovery of key vaccines to the advancement of research on a range of diseases, among them hypertension, kidney failure and cancer. This book is essential reading for anyone curious about the role of animal experimentation in the history of science from the nineteenth century to the present.

Wood artefacts rarely survive from the Early Stone Age since they require exceptional conditions for preservation; consequently, we have limited information about when and how hominins used this basic raw material 1 . We report here on the earliest evidence for structural use of wood in the archaeological record. Waterlogged deposits at the archaeological site of Kalambo Falls, Zambia, dated by luminescence to at least 476 ± 23 kyr ago (ka), preserved two interlocking logs joined transversely by an intentionally cut notch. This construction has no known parallels in the African or Eurasian Palaeolithic. The earliest known wood artefact is a fragment of polished plank from the Acheulean site of Gesher Benot Ya’aqov, Israel, more than 780 ka (refs. 2 , 3 ). Wooden tools for foraging and hunting appear 400 ka in Europe 4 – 8 , China 9 and possibly Africa 10 . At Kalambo we also recovered four wood tools from 390 ka to 324 ka, including a wedge, digging stick, cut log and notched branch. The finds show an unexpected early diversity of forms and the capacity to shape tree trunks into large combined structures. These new data not only extend the age range of woodworking in Africa but expand our understanding of the technical cognition of early hominins 11 , forcing re-examination of the use of trees in the history of technology 12 , 13 . Wooden artefacts from waterlogged deposits in Zambia dating back 477 ka indicate hitherto unknown sophistication in woodworking at an early date.

Extrinsic mortality risks calibrating fast life history (LH) represent a species-general principle that applies to almost all animals including humans. However, empirical research also finds exceptions to the LH principle. The present study proposes a maternal socialization hypothesis, whereby we argue that the more human-relevant attachment system adds to the LH principle by up- and down-regulating environmental harshness and unpredictability and their calibration of LH strategies. Based on a longitudinal sample of 259 rural Chinese adolescents and their primary caregivers, the results support the statistical moderating effect of caregiver–child attachment on the relation between childhood environmental adversities (harshness and unpredictability) and LH strategies. Our theorizing and findings point to an additional mechanism likely involved in the organization and possibly the slowdown of human LH.

Despite dozens of empirical studies and a growing body of meta-analytic work, there is little consensus regarding the efficacy of cognitive training. In this review, we examine why this substantial corpus has failed to answer the often-asked question, “Does cognitive training work?” We first define cognitive training and discuss the general principles underlying training interventions. Next, we review historical interventions and discuss how findings from this early work remain highly relevant for current cognitive-training research. We highlight a variety of issues preventing real progress in understanding the underlying mechanisms of training, including the lack of a coherent theoretical framework to guide training research and methodological issues across studies and meta-analyses. Finally, suggestions for correcting these issues are offered in the hope that we might make greater progress in the next 100 y of cognitive-training research.

Biodiversity data derive from myriad sources stored in various formats on many distinct hardware and software platforms. An essential step towards understanding global patterns of biodiversity is to provide a standardized view of these heterogeneous data sources to improve interoperability. Fundamental to this advance are definitions of common terms. This paper describes the evolution and development of Darwin Core, a data standard for publishing and integrating biodiversity information. We focus on the categories of terms that define the standard, differences between simple and relational Darwin Core, how the standard has been implemented, and the community processes that are essential for maintenance and growth of the standard. We present case-study extensions of the Darwin Core into new research communities, including metagenomics and genetic resources. We close by showing how Darwin Core records are integrated to create new knowledge products documenting species distributions and changes due to environmental perturbations.
