The Science of Life

The Science of Life is a popular biology book by H. G. Wells, Julian Huxley, and G. P. Wells. It was published in 1929–1930 in three volumes and later as a single volume, and it explains the major ideas of biology as scientists understood them in the 1920s. The book has been called the first modern biology textbook and a clear, engaging introduction to the subject.

Wells wanted to reach intelligent, non-specialist readers—people who were curious and capable of following big ideas but did not need to be experts. Julian Huxley and Gip (G. P.) Wells wrote much of the text, while Wells himself edited, managed publishers, and kept a tight writing schedule. The project began while Wells was coping with his wife’s illness, and he often used the work to help him through his loss. The three authors are presented as a single, cooperative authoring team.

Originally issued as 31 parts, the book was later bound into three volumes (1929–30) and, in 1931, released as a single volume. It includes more than 300 illustrations. The book was very successful, though the Great Depression slowed sales and reduced book-club memberships.

Contents and themes
- The early volumes cover the living body, how life is organized, patterns of life, and the facts and theory of evolution. They also discuss reproduction, heredity, and the development of sex, and trace the history and adventure of life, as well as the drama of life.
- One part, Book Three, presents a clear, bold case for evolution with sections on the evidence from rocks, living organisms, and human evolution—an approach notable for its boldness just a few years after the Scopes Trial.
- Book Four focuses on evolution and its controversies, but argues that Darwin’s broad ideas remain essentially sound.
- The book also introduces ecological ideas long before they became mainstream, highlighting pollution, endangered species, and the value of alternative energy sources. It also emphasizes behavior and, to some extent, Jungian psychology.

Towards the end, the text moves from science toward moral guidance. In a chapter on conduct, it urges readers to be self-disciplined, considerate, trustworthy, and well-mannered. The closing pages question the credibility of personal immortality and encourage readers to find meaning by participating in something larger—whether that means a higher power or "Man" as a whole.

Publication history and impact
- The work appeared first in 31 parts and was bound into three volumes (1929–30). A one-volume edition followed in 1931, with further revisions and reprints, including a revised 1938 edition with a new preface by Wells.
- In the UK, Cassell published several volumes with themed sections such as The Living Body; Patterns of Life; Evolution—Fact and Theory; Reproduction and heredity; The history and adventure of life; The drama of life; How animals behave; Man’s mind and behaviour; Biology and the human race.
- In the United States, Doubleday issued editions in 1931, 1934, and 1939, including a four-volume limited edition. The book was translated into French and used in schools during World War II, including a one-volume military edition.
- The page counts and editions vary by edition, with a commonly cited edition around 1,500 pages in total.

Legacy
The Science of Life helped popularize biology, introduce ecological thinking, and bridge scientific knowledge with public understanding. It influenced how people thought about evolution, environment, and the place of humans in nature, while also shaping later discussions on science, ethics, and society.
