Since the beginnings of conscious thought, human beings have looked with wonder at the world around them. Perhaps the most significant part of the development of consciousness was self-awareness, and with it came the profoundest of biological questions: “Where did I come from?”.
The Coiled Spring starts with the most fundamental of premises in modern developmental biology: All cells contain the same genetic information. He then logically progresses to ask, if this is so, why all cells in the body are not the same. The rest of the book (and indeed embryogenesis) answers this question.
Few people have had as great an impact on the modern environmental movement as has the great writer and scientist Rachel Carson. This readable and up-to-date biography traces the famous environmentalist's development as a writer from earliest childhood through the publication of her best-known work Silent Spring (1962). Although Carson is now remembered almost exclusively for Silent Spring, which exposed the dangers of pesticides, this book was preceded by three best-sellers about the ocean environment: Under the Sea-Wind (1941), The Edge of the Sea (1955), and The Sea Around Us (1951), which catapulted her to fame.
