Children of the Sun
A spirited survey of humanity's historical and modern efforts to harness sun-based energy reveals how the human race's successes have hinged directly on effective uses of sun energy, cites rates in pollution and global warming as warning signs of fossil fuel limits, and makes optimistic predictions about future innovations. 13,000 first printing.
A History of Energy Flows
This book presents a global and historical perspective of energy flows during the last millennium. The search for sustainable energy is a key issue dominating today’s energy regime. This book details the historical evolution of energy, following the overlapping and slow flowing transitions from one regime to another. In doing so it seeks to provide insight into future energy transitions and the means of utilizing sustainable energy sources to reduce humanity’s fossil fuel footprint. The book begins with an examination of the earliest and most basic forms of energy use, namely, that of humans metabolizing food in order to work, with the first transition following the domestication and breeding of horses and other animals. The book also examines energy sources key to development during the industrialization and mechanization, such as wood and coal, as well as more recent sources, such as crude oil and nuclear energy. The book then assesses energy flows that are at the forefront of sustainability, by examining green sources, such as solar, wind power and hydropower. While it is easy to see energy flows in terms of “revolutions,” transitions have taken centuries to evolve, and transitions are never fully global, as, for example, wood remains the primary fuel source for cooking in much of the developing world. This book not only demonstrates the longevity of energy transitions but also discusses the possibility for reducing transition times when technological developments provide inexpensive and safe energy sources that can reduce the dependency on fossil fuels. This book will be of great interest to students and scholars of energy transitions, sustainable energy and environmental and energy history.

The Wrong Ape for Early Human Origins examines ways in which the chimpanzee referential model has exerted a primary influence on evolutionary theory, dominating portraits of proto- and early human social life, and in the broader sense, of human nature itself. Evidence on which this model is based is revisited, along with new cross-disciplinary findings that point to alternative scenarios for hominin phylogeny, ecology and subsistence, primeval kinship, cognition and language, and the respective roles played by aggression and cooperation as evolutionary drivers. Recent advances in phylogenetics, evolutionary biology, and new additions to the fossil record are rendering linear, monotypic models obsolete. Contemporary theories on species divergence and change over time are shifting attention from ancient genotypes to factors that influence gene expression, and from innate prescriptive behaviors to epigenesis and the capacity for behavioral plasticity. This broader platform has the potential to fundamentally revise current notions about the basic nature, phenotypic traits, and lifeways of ancestral humans. It informs a different profile of our progenitors—one that reflects greater ecological bandwidth, reliance on creative niche construction, and hominin agency in the structuring of ancient reproductive and social groups.
