Originally published in 1990 with McGraw-Hill, and then later that year as a Bantam paperback, Biospheres, Dorion Sgan's first sole-authored book, was translated into French and Italian. Now back in print the book explores a "Nietzschean ecology," suggesting that individuality is not confined just to bacteria, eukaryotes, and multicellular organisms, but over evolutionary time appears at ever-greater scales, ultimately leading to the reproduction of the Earth itself. The book interweaves themes ranging from biomineralization and science fiction to nature's astounding creativity as it makes its case for a posthuman view of the evolutionary process.
