Description

The study of life in our universe has been given the name 'astrobiology'. It is a relatively new subject, but not a new discipline since it brings together several mature fields of science including astronomy, geology, biology, and climatology. An understanding of the singular conditions that allowed the only example of life that we know exists to emerge and survive on our turbulent planet is essential if we are to seek answers to two fundamental questions facing humanity: will life (and especially human life) continue on Earth, and does life exist elsewhere in the universe?

Astrobiology of Earth adopts a unique approach that differs from most texts in the field which focus on the possibility of extraterrestrial life. In contrast, the central theme of this book is the fortuitous combination of numerous cosmic factors that together produced the special environment which enabled the emergence, persistence and evolution of life on our own planet, culminating in humanity. This environment has been subject to constant and chaotic change during life's 3.6 billion year history. The geologically very recent appearance of humans and their effect on the biosphere is discussed in relation to its deterioration as well as climate change. The search for extraterrestrial life is considered with a view to the suggestion that humans may escape a depleted Earth by colonizing the universe.

This book contributes to our understanding of astrobiology from the perspective of life on Earth and especially human welfare and survival. Astronomical and geological phenomena are related in turn to their biological relevance and impact. This introductory text assumes little or no prior knowledge of more specialized scientific fields and is designed for undergraduate and graduate level students taking related courses in departments of biology, earth science/geology, and environmental science. It will also serve as a useful biology primer for astronomy majors.

Features

• Based on a proven course structure
• Adopts an anthropocentric approach
• Astronomical and geological principles discussed in relation to biological relevance and impact
• Requirement of little or no background in geology, astronomy and meteorology

Reviews

"Astrobiology of Earth is a fascinating journey to the world of astrobiology, with life on Earth as its central theme. Gale manages to convey his enthusiasm and curiosity which makes the reading a very enjoyable experience."--Professor Yigal Erel, Chair, Institute of Earth Sciences, Hebrew University of Jerusalem, Israel

"The book is an excellent, everybody's primer to astrobiology in its most expansive form, which convincingly demonstrates how knowledge in this field can help us to understand life on our tumultuous planet and rationally address the great ecological challenges of our times."--Professor Andrew Pohorille, Senior Scientist, Space Science and Astrobiology Division, NASA Ames Research Center

"In Astrobiology of Earth , readers are treated to a fresh perspective on the science of astrobiology, written by a capable researcher who innately understands the value of a multi- and interdisciplinary approach to the scientific study of life: its origins, evolution, and distribution. The book is an excellent resource for someone wishing to know what astrobiology is all about."--Dr. John D. Rummel, East Carolina University, Formerly NASA Senior Scientist for Astrobiology, and NASA Planetary Protection Officer

"The approach is modern, broadly interdisciplinary, and with a lively personal writing style suitable for students from many backgrounds."--Professor Park S. Nobel, Distinguished Professor of Biology, Emeritus, University of California, Los Angeles
