Our planet earth is a system - scarcely understood - of geological, biological und cosmic processes of great variety, which make it an interesting object of research. The papers listed here deal with topics of a series of lectures open to the public, presented at the Academy of Sciences and at the Georg August University of Göttingen, which were organised by the publishers of this book. It is the publishers' aim to bring before the public a few important and interesting geoscientific aspects. Needless to say, there is no claim to cover all aspects of this subject area. However, the publishers would like to initiate readers to concentrate more deeply on scientific topics. The selected material should help them to find their way through the diversity of this branch of research.

Many of the characteristics that distinguish plants from other living organisms can be traced to their bacterial origin early in the history of life. These features-such as a multicellular haploid life stage, prevalent hermaphroditism, self-fertilization, and general dependence on biotic and abiotic vectors for reproduction-stem directly from the plant's ability to obtain energy from the sun. This novel mode of energy capture had far-ranging implications for plant evolution. It not only fueled the tremendous diversification of life on Earth that followed, but also had far-ranging implications for the evolution of photosynthetic microorganisms and eventually for land plants. Understanding the evolutionary processes for the proliferation and diversification of plants requires an appreciation of their unique biological features. While the processes of mutation, selection, genetic drift, and gene flow remain the same for both plants and animals, there are specific characteristics of plants that modify the way their evolution is implemented. Unique traits of plants affect everything from the fate of mutations, through exposure to selection in a haploid life phase, to the distribution of genetic variation within populations, and ultimately the rates and patterns of diversification. This book examines the origins of the unique evolutionary features of plants, as well as their implications for evolutionary processes. Author Mitchell B. Cruzan provides contemporary discussion of subjects including population genetics, phylogeography, phylogenetics, ecological genetics, and genomics. The book fills a need for modern coverage of these topics, all of which are essential to a wide range of advanced courses in plant biology..

"Does the field of evolution differ from other sciences? The data show that there are two types of evolution, microevolution and macroevolution, with a clear boundary between them. The surprising results show that there is a universal disconnect between the data and the conclusions that claim to show the larger changes of macroevolution. The author has revealed patterns of deviations from standard scientific methods in these studies. For the first time, evolutionary data have been summarized to describe both what evolution can and cannot accomplish. The author shows the reader how to recognize the different ways in which the evidence for microevolution within and between some species differs from the unsupported macroevolution of most species"--
