This review is from: The Reason Why: The Miracle of Life on Earth (Hardcover)
This is an absorbing read through a wide range of evidence about the possibilities of intelligent life elsewhere in the Universe. Each arguement, concerning the chances of life evolving, is supported by informed evidence which,however,can sometimes be lengthy.The use of a diagram would often help with both length and clarity; an example is the use of a frontal and an edge view of our Galaxy.There are some ambiguities, which suggest more editing was needed. An example here is the doubtful expression:- "quartz crystallises out of the molten magma leaving it richer in silica"(quartz is silica).A reader will finish feeling that he,or she, has had a refreshing experience of the dependence of human existance on a narrow band of conditions in each of the Galaxy, Sun, Solar System and the Earth.This precious Earth has provided a home for evolution over a vast period of time.
