Book Description
The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

Book Description
This book discusses the controversial and conflicting hypotheses on the origin of angiosperms, which was generally assumed to be restricted to the Cretaceous and later ages. Since publishing the first edition of “The Dawn of Angiosperms” in 2010, several important advances have been made in this field of science, namely 1) the discovery of new fossil angiosperms from the Jurassic; 2) European researchers discovering angiosperm-like pollen from the Triassic; and most importantly 3) the discovery of a perfect flower from the Jurassic. All of these findings are at odds with the currently widely accepted evolutionary theories, and thus call upon us to critically reassess botanical theory. Accordingly, the new edition of this book not only includes more new fossil taxa, but also documents them in greater detail and corrects many commonly held misconceptions. In so doing, it makes related studies and teaching on the early history of angiosperms more realistic, concrete, and tangible, providing concrete fossil evidence as the basis for future research, and helping to distinguish the most accurate botanical hypotheses.

Book Description
Determining the precise timing for the evolutionary origin of groups of organisms has become increasingly important as scientists from diverse disciplines attempt to examine rates of anatomical or molecular evolution and correlate intrinsic biological events to extrinsic environmental events. Molecular clock analyses indicate that many major groups

Book Description
Plant molecular biology has produced an ever-increasing flood of data about genes and genomes. Evolutionary biology and systematics provides the context for synthesizing this information. This book brings together contributions from evolutionary biologists, systematists, developmental geneticists, biochemists, and others working on diverse aspects of plant biology whose work touches to varying degrees on plant molecular evolution. The book is organized in three parts, the first of which introduces broad topics in evolutionary biology and summarizes advances in plant molecular phylogenetics, with emphasis on model plant systems. The second segment presents a series of case studies of gene family evolution, while the third gives overviews of the evolution of important plant processes such as disease resistance, nodulation, hybridization, transposable elements and genome evolution, and polyploidy.

Book Description
This book presents coverage of the principles and practice of molecular clocks, which have provided fascinating and unprecedented insights into the evolutionary timescale of life on earth. It begins by following the early development of the molecular evolutionary clock in the 1960s, and leads to the complex statistical approaches that are now used to analyse genome sequences. The chapters of this book have been contributed by leading experts in the field and address the important issues of evolutionary rates, molecular dating, and phylogenomic analysis. This is the first time that these different aspects of the molecular clock have been brought together in a single, comprehensive volume. It is an invaluable reference for students and researchers interested in evolutionary biology, genetic analysis, and genomic evolution.

Book Description
In this timely new 2-volume treatise, experts from around the world have banded together to produce a first-of-its-kind synopsis of the exciting and fast moving field of plant evolutionary genomics. In Volume I of Plant Genome Diversity, an update is provided on what we have learned from plant genome sequencing projects. This is followed by more focused chapters on the various genomic “residents” of plant genomes, including transposable elements, centromeres, small RNAs, and the evolutionary dynamics of genes and non-coding sequences. Attention is drawn to advances in our understanding of plant mitochondrial and plastid genomes, as well as the significance of duplication in genic evolution and the non-independent evolution among sequences in plant genomes. Finally, Volume I provides an introduction to the vibrant new frontier of plant epigenomics, describing the current state of our knowledge and the evolutionary implications of the epigenomic landscape.

Book Description
This book covers the hot topics of angiosperm structure and evolution in several chapters discussing vegetative and reproductive characters. It also looks at the implications of ancestral angiosperm characters for an herbaceous origin and the phylogeny of angiosperms from a structure and molecular perspective.

Book Description
Biogeography is a diverse subject, traditionally focusing on the distribution of plants and animals at different taxonomic levels, past and present. Modern biogeography also puts emphasis on the ecological character of the world vegetation types, and on the evolving relationship between humans and their environment. Panbiogeography describes a new synthesis of sciences of plant and animal distribution. The book emphasizes that the geographical patterns of animal and plant distribution contribute directly to the understanding and interpretation of evolutionary history. Geographic location is reintroduced as a critical element of both biogeography and evolutionary biology. The authors present chapters exploring the roles of geology, ecology, evolution in panbiogeographic theory, and introduce new methods, modes of classification, and ways of measuring biodiversity.
