"This work explores how living organisms have been classified at the highest level. The earliest ideas of nature emphasised transformation. Aristotle recognised that certain objects in the sea share properties of plants and animals; these became known as zoophytes. The narrative follows zoophytes and other transgressive beings through subsequent philosophical and religious traditions, myths, travellers' tales, the occult literature, alchemy, scholasticism, the consolidation of vernacular languages, and the rise of scientific botany and zoology. Leeuwenhoek's discovery of microscopic beings, and Trembley studies on Hydra, complicated the plant-animal dichotomy. Transformation returned as Needham, Buffon and others observed plant material to generate motile animalcules; Linnaeus proposed a Regnum Chaoticum. New challenges arose as the Great Chain of Being was abandoned, algae were observed to liberate free-swimming zoospores, and cell theory was refined. Biology developed differently in France, Germany and Britain, and we follow the rise and fall of supernumerary kingdoms in each environment. Haeckel positioned Protista as one of two, three or four kingdoms. In the Twentieth century the living world was divided between prokaryotes and eukaryotes, while mitochondria and plastids were recognised as descendants of endosymbiotic bacteria. Molecular evidence revealed three domains (Archaea, Bacteria, Eukaryota), although many genomes are linked in a dynamic network of genetic relationships. Environmental genomes now threaten to undermine Eukaryota as an independent domain of life"--

Kingdoms, Empires, and Domains explores the history of the idea that there is more to the living world than plants and animals. Progressing chronologically through philosophical, religious, literary, and other pre-scientific traditions, leading molecular systematist Mark A. Ragan traces how transgressive creatures such as sponges, corals, algae, fungi, and diverse microscopic beings have been described, categorized, and understood throughout history. The book also explores how the concept of a "third kingdom of life" evolved within the fields of scientific botany and zoology, and continues to evolve up to the present day.

An all-inclusive catalogue of the world's living diversity, Five Kingdoms defines and describes the major divisions, or phyla, of nature's five great kingdoms - bacteria, protoctists, animals, fungi, and plants - using a modern classification scheme that is consistent with both the fossil record and molecular data. Generously illustrated and remarkably easy to follow, it not only allows readers to sample the full range of life forms inhabiting our planet but to familiarize themselves with the taxonomic theories by which all organisms' origins and distinctive characteristics are traced and classified.

Now published by Academic Press and revised from the author's previous Five Kingdoms Third edition, this extraordinary, all inclusive catalogue of the world’s living organisms describes the diversity of the major groups, or phyla, of nature’s most inclusive taxa. Developed after consultation with specialists, this modern classification scheme is consistent both with the fossil record and with recent molecular, morphological and metabolic data. Generously illustrated, now in full color, Kingdoms and Domains is remarkably easy to read. It accesses the full range of life forms that still inhabit our planet and logically and explicitly classifies them according to their evolutionary relationships. Definitive characteristics of each phylum are professionally described in ways that, unlike most scientific literature, profoundly respect the needs of educators, students and nature lovers. This work is meant to be of interest to all evolutionists as well as to conservationists, ecologists, genomicists, geographers, microbiologists, museum curators, oceanographers, paleontologists and especially nature lovers whether artists, gardeners or environmental activists. Kingdoms and Domains is a unique and indispensable reference for anyone intrigued by a planetary phenomenon: the spectacular diversity of life, both microscopic and macroscopic, as we know it only on Earth today. New Foreword by Edward O. Wilson The latest concepts of molecular systematics, symbiogenesis, and the evolutionary importance of microbes Newly expanded chapter openings that define each kingdom and place its members in context in geological time and ecological space Definitions of terms in the glossary and throughout the book Ecostrips, illustrations that place organisms in their most likely environments such as deep sea vents, tropical forests, deserts or hot sulfur springs A new table that compares features of the most inclusive taxa Application of a logical, authoritative, inclusive and coherent overall classification scheme based on evolutionary principles

"In this extraordinary volume, Krishan Kumar provides us with a brilliant tour of some of history's most important empires, demonstrating the critical importance of imperial ideas and ideologies for understanding their modalities of rule and the conflicts that beset them. In doing so, he interrogates the contested terrain between nationalism and empire and the legacies that empires leave behind."--Mark R. Beissinger, Princeton University "This is an excellent book with original insights into the history of empires and the discourses and rhetoric of their rulers and defenders. Kumar's writing is lively and free of jargon, and his research is prodigious. He manages to bring clarity and perspective to a complex subject."--Ronald Grigor Suny, author of "They Can Live in the Desert but Nowhere Else": A History of the Armenian Genocide "A masterly piece of work."--Anthony Pagden, author of The Burdens of Empire: 1539 to the Present
