    This book comprehensively explores the early evolution of life and the Archean environment. Topics include the differences between prokaryotes and eukaryotes, variations in metabolisms, concepts of ecosystems and biogeochemical cycles (nitrogen, sulfur, phosphorous), Archean geology and environments, and the widely accepted early evolutionary history of life. The text addresses controversies regarding early life and its environment, particularly the unusual microfossil assemblages from the 3.4 Ga Strelley Pool Formation and the 3.0 Ga Farrel Quartzite of Western Australia. Readers will get a fuller picture of the Archean world, and an appreciation of many still unresolved questions.

    Key Features

    Kenichiro Sugitani is Professor in the Graduate School of Environmental Studies at Nagoya University, Chikusa, Nagoya. He has published over 70 scientific papers and received the 1995 Geochemical Society of Japan encouragement award for contributions to understanding of geochemistry and origin of ancient siliceous sediments including Archean cherts. He has undertaken fieldwork in the Pilbara Craton and mapped the Goldsworthy greenstone belt, and discovered microfossils from the 3.0 Ga Farrel Quartzite. He is an associate member of Australian Centre for Astrobiology at the University of New South Wales, and serves as regional editor of Astrobiology and a member of editorial advisory board of Geobiology.
