From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The...

Life As we Know It "LAKI"] covers several aspects of Life, ranging from the prebiotic level, origin of life, evolution of prokaryotes to eukaryotes and finally to various affairs of human beings. Although it is hard to define Life, one can, however, characterize it and describe its features. Topics treated are categories of bacteria, algae and fungi, conscience, philosophy, theology, aesthetics, appearance of sport and life destiny, life after clinical death, and thoughts of the world to come ("Olam Haba").

The various chapters have been written so that they are accessible to all...

This book provides information about microbial mats, from early fossils to modern mats located in marine and terrestrial environments. Microbial mats - layered biofilms containing different types of cells - are most complex systems in which representatives of various groups of organisms are found together. Among them are cyanobacteria and eukaryotic phototrophs, aerobic heterotrophic and chemoautotrophic bacteria, protozoa, anoxygenic photosynthetic bacteria, and other types of microorganisms.

These mats are perfect models for biogeochemical processes, such as the cycles of chemical...

The debate between divine action, or faith, and natural selection, or science, is garnering tremendous interest. This book ventures well beyond the usual, contrasting American Protestant and atheistic points of view, and also includes the perspectives of Jews, Muslims, and Roman Catholics. It contains arguments from the various proponents of intelligent design, creationism, and Darwinism, and also covers the sensitive issue of how to incorporate evolution into the secondary school biology curriculum. Comprising contributions from prominent, award-winning authors, the book also contains...

In this Journey to Microbial Worlds we present the diversity of microorganisms, from the state of fossil microbes in Archaean age rocks to the possibilities of extraterrestrial life. This volume discusses the extremophiles living in harsh environments (from our anthropocentric point) and describes them in considerable detail. Some chapters also review topics such as symbiosis, bacterial luminescence, methanogens, and petroleum-grown cells. The final chapters of this book shed new light on astrobiology and speculate on extremophiles as candidates for extraterrestrial life. All...

Genesis - In The Beginning deals with the origin and diversity of Life and early biological evolution and discusses the question of where (hot or cold sources) and when the beginning of Life took place. Among the sections are chapters dealing with prebiotic chemical processes and considering self-replication of polymers in mineral habitats. One chapter is dedicated to the photobiological regime on early Earth and the emergence of Life. This volume covers the role of symmetry, information and order (homochrial biomolecules) in the beginning of Life. The models of protocells and the...

When one picks up a multiauthored book in a series like this, one wonders what will be distinctive about its contents. one wonders about the "Concept of Symbiosis. " does it have the same meaning for all authors and all potential readers? one is further tempted to question the concept of stress. What is the meaning of the c- cept of stress? Some change in the biotic or abiotic aspects of the environment or habitat of the symbiotic partners? many might support the more general def- tion of symbiosis credited to de bary (1879), that symbiosis is the living together of separately named...

Algae and Cyanobacteria in Extreme Environments is a unique collection of essays, contributed by leading scientists from around the world, devoted to algae and some related microbes observed in unexpected harsh habitats, which it seems are an oasis or Garden of Eden for these organisms. This timely book on Extremophilic algae, including its especially impressive micrographs, may provide clues about the edges of life on Earth and possibly elsewhere in the universe.

Defining locations from the anthropomorphic point of view, the environments explored ranges from severe and distant to...

Symbiosis is the fourth volume in the series Cellular Origin and Life in Extreme Habitats (COLE). Fifty experts, from over a dozen countries, review their current studies on different approaches to these phenomena. The chapters present various aspects of symbiosis from gene transfer, morphological features, and biodiversity to individual organisms sharing mutual cellular habitats. The origin of the eukaryotic phase is discussed with emphasis on cyanelles, H syntrophy, N₂ fixation, and S-based symbiosis (as well as the origin of mitochondrion,...

Many Microorganisms and some macro-organisms can live under extreme conditions. For example, high and low temperature, acidic and alkaline conditions, high salt areas, high pressure, toxic compounds, high level of ionizing radiation, anoxia and absence of light, etc. Many organisms inhabit environments characterized by more than one form of stress (Polyextremophiles). Among them are those who live in hypersaline and alkaline, hot and acidic, cold/hot and high hydrostatic pressure, etc. Polyextremophiles found in desert regions have to copy with intense UV irradiation and desiccation, high as...
