We Might Be All Alone,
This review is from: Rare Earth: Why Complex Life is Uncommon in the Universe (Hardcover)
These two authors have written a highly informative book to support their thesis that we might well be the only multi-celled organisms in the universe. It should be stressed that Ward and Brownlee feel strongly that there are probably simple, bacteria like creatures on other planets, but nothing more complex. This is a most interesting book even if you do not agree with their hypotheses. It provides an entertaining and accessible summary of the biological, cosmological, and geological science involved in the development of our home planet. W&B feel that the necessary conditions for complex life are so numerous that few, if any, planets elsewhere could meet the requirements.
Read this book and see: 1. Why the moon and Jupiter are essential for our existence. 2. Why a system of plate tectonics is vital for the development of life forms. 3. The effects that mass extinctions have had on evolution. 4. Why life may have originated in the deep ocean near hydrothermal vents. 5. Why earth is very lucky to be located on the far edge of our galaxy.
For the scientific oriented layman this book is a true gem.
