Life is a diverse and ubiquitous phenomenon on Earth, characterized by fundamental features distinguishing living bodies from nonliving material. Yet it is also so complex that it has long defied precise definition. This book from a seasoned biologist offers new insights into the nature of life by illuminating a fascinating architecture of dualities inherent in its existence and propagation. Life is connected with individual living beings, yet it is also a collective and inherently global phenomenon of the material world. It embodies a dual existence of cycles of phenotypic life, and their unseen driver - an uninterrupted march of genetic information whose collective immortality is guaranteed by individual mortality. Although evolution propagates and tunes species of organisms, the beings produced can be regarded merely as tools for the survival and cloning of genomes written in an unchanging code. What are the physical versus informational bases and driving forces of life, and how do they unite as an integrated system? What does time mean for individuals, life on the global scale, and the underlying information? This accessible examination of principles and evidence shows that a network of dualities lies at the heart of biological puzzles that have engaged the human mind for millennia.

What are life and death? Is it possible to understand their essence and give clear definitions? Countless books and articles have been devoted to trying to answer these intriguing questions. However, there are still no definite and generally accepted answers. The intrigue remains. And meanwhile, human attempts to vanquish death and achieve immortality continue apace. This book is an attempt to answer the eternal questions about life and death by analyzing, synthesizing, and rethinking the known facts that characterize life. The material here should be of particular interest, as it contains many hypotheses, philosophical generalizations, and well informed speculations. What is most important for life - matter, energy, or information? How are individual lives and the phenomenon of life in general related? What serves what – does the genome serve the cell or does the cell serve the genome? What is the value of life and death? Can we become immortal? The inquisitive reader will find original answers to these and other exciting questions in the pages of this stimulating book.
