DOWNLOAD EBOOKLife on Earth has been evolving and interacting with the surface and atmosphere for almost four billion years. Fossils provide a powerful tool in the study of the Earth and its history. They also provide important data for evolutionary studies and contribute to our understanding of the extinction of organisms and the origins of modern biodiversity. Introduces the study of fossils in a simple and straightforward manner. Short chapters introduce the main topics in the current study of fossils. The most important fossil groups are discussed, from microfossils through invertebrates to vertebrates and plants, followed by a brief narrative of life on earth. Diagrams are central to the book and allow the reader to see most of the important data 'at a glance'. Each topic covers two pages and provides a self-contained suite of information or a starting point for future study.

DOWNLOAD EBOOKThe literature of paleobiology is brimming with qualifiers and cautions about using species in the fossil record, or equating such species with those recognized among living organisms. Species and Speciation in the Fossil Record digs through this literature and surveys the recent research on species in paleobiology. In these pages, experts in the field examine what they think species are - in their particular taxon of specialty or more generally in the fossil record. They also reflect on what the answers mean for thinking about species in macroevolution. The first step in this approach is an overview of the Modern Synthesis, and paleobiology’s development of quantitative ways of documenting and analyzing variation with fossil assemblages. Following that, this volume’s central chapters explore the challenges of recognizing and defining species from fossil specimens, and show how with careful interpretation and a clear species concept, fossil species may be sufficiently robust for meaningful paleobiological analyses. Tempo and mode of speciation over time are also explored, exhibiting how the concept of species, if more refined, can reveal enormous amounts about the interplay between species origins and extinction and local and global climate change.
