So begins the story of one family in a changing world, where the apocalyptic mingles with the everyday; a father battles a biblical storm; an immigrant is mysteriously drawn to the art of beekeeping; a young girl’s diary chronicles a pandemic; and a young man finds solace in building virtual recreations of the dead…

Book excerpt: IT’S A POST-ECOCAUST WORLD. WELCOME TO IT. In the San Jose of tomorrow, all of nature is gengineered—from the warm-blooded plants to the designer people. But even in a rigidly controlled biosystem, with its pheromone-induced social order, the American dream is still the American dream. Caught between these new-old worlds, Rigo is on his way up—he’s going to be part of tomorrow, even if it means he has to leave today behind. Written off as a sellout on the streets of his old ’hood, Rigo’s got his own ap in an aplex, a 9-to-5er, and a girl. He’s got opportunity. If he works hard, his job with a heavyweight politicorp could give him a chance to move up in the clades. But when he’s chosen as part of a team to construct a new colony on a nearby comet, Rigo smells a setup. And when disaster strikes, he learns that if there’s a way to bend the rules, there’s also a way to break them…

Download or read book The Origin of Higher Clades written by Rui Diogo and published by CRC Press. This book was released on 2020-03-05 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides insight on the osteology, myology, phylogeny and evolution of Osteichthyes. It not only provides an extensive cladistic analysis of osteichthyan higher-level inter-relationships based on a phylogenetic comparison of 356 characters in 80 extant and fossil terminal taxa representing all major groups of Osteichthyes, but also analyses various terminal taxa and osteological characters. And also provides a general discussion on issues such as the comparative anatomy, homologies and evolution of osteichthyan cranial and pectoral muscles, the development of zebrafish cephalic muscles and the implications for evolutionary developmental studies, the origin homologies and evolution of one of the most peculiar and enigmatic structural complexes of osteichthyans, the Weberian apparatus, and the use of myological versus osteological characters in phylogenetic reconstructions.

Download or read book Conceptual Issues in Modern Human Origins Research written by Geoffrey A. Clark and published by Transaction Publishers. This book was released on with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: While those who study human origins now agree that the evolution of modern human form extends back much further in time than the evolution of modern human behavior, they disagree sharply as to how to interpret the substantive data. Two fundamentally incommensurate interpretations of our origins, the "Replacement" camp and the "Continuity" camp, have now emerged out of pre-existing models and theories that go back to the last quarter of the 19th century. This book contends that these positions are based on radically different biases and assumptions about what the remote human past was like. The purpose of this volume is to examine those conceptual differences, not to arrive at a consensus, but rather to explore the reasons why a consensus might never be possible.

Download or read book Contributions Celebrating Kumar Krishna written by Michael S. Engel and published by PenSoft Publishers LTD. This book was released on 2011-11-21 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present issue of ZooKeys comprises a series of papers honoring Prof. Kumar Krishna, the leading au-thority on the systematics and biology of termites (Isoptera). After becoming exposed to termite systematics under the tutelage of Mittan L. Roonwal in India, Kumar received his doctoral training from the legendary termite systematist and evolutionary biologist Alfred E. Emerson at the University of Chicago. Subsequently, Kumar moved to the City University of New York and the American Museum of Natural History from where, even today, he has produced some of the most important contributions to the study of termites, most notably his two-volume set, Biology of Termites (1969?1970, Academic Press), and the forthcoming monumental Treatise on the Isoptera of the World (AMNH). Herein colleagues and friends recognize his lifetime of accomplishments in biological systematics by presenting original papers on insect lineages as diverse as termites and grasshoppers, and flies and bees, among others. A brief biographical account and list of his publications to date are provided.

Download or read book Myxozoan Evolution, Ecology and Development written by Beth Okamura and published by Springer. This book was released on 2015-04-01 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date review of the biology of myxozoans, which represent a divergent clade of endoparasitic cnidarians. Myxozoans are of fundamental interest in understanding how early diverging metazoans have adopted parasitic lifestyles, and are also of considerable economic and ecological concern as endoparasites of fish. Synthesizing recent research, the chapters explore issues such as myxozoan origins; evolutionary trends and diversification; development and life cycles; interactions with hosts; immunology; disease ecology; the impacts of climate change on disease; risk assessment; emerging diseases; and disease mitigation. This comprehensive work will appeal to a wide readership, from invertebrate zoologists, evolutionary biologists and developmental biologists to ecologists and parasitologists. It will also be of great practical interest to fisheries and conservation biologists. The identification of key areas for future research will appeal to scientists at all levels.
