This book explores the unity of life by asserting that the concept of information is the inner essence of what we today call life. It delves into the profound impact of information on our species, highlighting how humans are highly dependent on it for constant exchange with others. The book also examines less apparent roles of information in determining individual development from a fertilized egg to adulthood through genetic and epigenetic information.

Furthermore, the text extends its exploration to ecosystems and even prebiotic systems, where it suggests that information plays a critical role in their processes. It posits that nature continuously processes information, sending messages to itself and decoding them, effectively “talking” to itself. The systematic organization of these messages is likened to “languages” of nature.

Written by Cédric Gaucherel, the first edition of this book was published on December 31, 2018, under Wiley-ISTE with the ISBN-13: 978-1119579359. It offers a compelling argument that goes beyond conventional understandings of life and its processes.
