Using an interdisciplinary approach, the authors provide an adaptionist interpretation of the basic features of recombination, its evolutionary significance as a key process in reproduction and its importance in genetic mapping. The book synthesizes much recent information in the fields of evloutionary genetics of recombination, the analysis of genetic markers and breeding applications. The authors analyse recombination through a consideration of computer models, large Drosophila populations and an empirical approach to current theories. Practically-orientated readers will be interested in the discussion of a wide spectrum of mapping methods and the new algorithms proposed for genetic mapping of quantitative loci.
This book is about the contribution to evolutionary theory and agricultural technology of one of humankind's most dramatic imitations of the evolu tionary process, namely crop domestication, as exemplified by the progenitor of wheat, Triticum dicoccoides. This species is a major model organism and it has been studied at the Institute of Evolution, University of Haifa, since 1979. The domestication by humans of wild plants to cultivated ones during the last ten millennia is one of the best demonstrations of evolution. It is a process that has been condensed in time and advanced by artificial rather than natural selection. Plant and animal domestication revolutionized human cultural evolution and is the major factor underlying human civilization. A post-Pleistocene global rise in temperature following the ice age, i.e., climatic-environmental factors, may have induced the expansion of econom ically important thermophilous plants and in turn promoted complex forag ing and plant cultivation. The shift from foraging to steady production led to an incipient agriculture varying in time in various part of the world. In the Levant, agriculture developed out of an intensive specialized exploitation of plants and animals. Natufian sedentism, followed by rapid population growth and resource stress, induced by the expanding desert, coupled with available grinding technology, may have triggered plant domestication.

World-class science and technology developed in the Soviet Union during Stalin's dictatorial rule under conditions of political violence, lack of international contacts, and severe restrictions on the freedom of information. Stalin's Great Science: The Times and Adventures of Soviet Physicists is an invaluable book that investigates this paradoxical success by following the lives and work of Soviet scientists ? including Nobel Prize-winning physicists Kapitza, Landau, and others ? throughout the turmoil of wars, revolutions, and repression that characterized the first half of Russia's twentieth century.The book examines how scientists operated within the Soviet political order, communicated with Stalinist politicians, built a new system of research institutions, and conducted groundbreaking research under extraordinary circumstances. Some of their novel scientific ideas and theories reflected the influence of Soviet ideology and worldview and have since become accepted universally as fundamental concepts of contemporary science. In the process of making sense of the achievements of Soviet science, the book dismantles standard assumptions about the interaction between science, politics, and ideology, as well as many dominant stereotypes ? mostly inherited from the Cold War ? about Soviet history in general. Science and technology were not only granted unprecedented importance in Soviet society, but they also exerted a crucial formative influence on the Soviet political system itself. Unlike most previous studies, Stalin's Great Science recognizes the status of science as an essential element of the Soviet polity and explores the nature of a special relationship between experts (scientists and engineers) and communist politicians that enabled the initial rise of the Soviet state and its mature accomplishments, until the pact eroded in later years, undermining the communist regime from within.
