Biology's First Law

The Tendency for Diversity and Complexity to Increase in Evolutionary Systems

McShea Daniel W., Brandon Robert N.

Life on earth is characterized by three striking phenomena that demand explanation: adaptation – the marvelous fit between organism and environment; diversity – the great variety of organisms; and complexity – the enormous intricacy of their internal structure. Natural selection explains adaptation. But what explains diversity and complexity? Daniel W. McShea and Robert N. Brandon argue that there exists in evolution a spontaneous tendency toward increased diversity and complexity, one that acts whether natural selection is present or not. They call this tendency a biological law – the Zero-Force Evolutionary Law, or ZFEL. This law unifies the principles and data of biology under a single framework and invites a reconceptualization of the field of the same sort that Newton's First Law brought to physics.

"Biology's First Law" shows how the ZFEL can be applied to the study of diversity and complexity and examines its wider implications for biology. Intended for evolutionary biologists, paleontologists, and other scientists studying complex systems, and written in a concise and engaging format that speaks to students and interdisciplinary practitioners alike, this book will also find an appreciative audience in the philosophy of science.

Reviews

"The ZFEL will be obvious to some, heretical to others, so the book will be controversial. But at the same time, the argument is rich enough to convince a skeptic, provided that skeptic is open-minded. A novel contribution of far-reaching importance in evolutionary biology" – Michael Foote, University of Chicago

"'Biology's First Law' is an original and unusual book. A hybrid of theoretical biology and philosophy of science, it addresses both conceptual and empirical problems... a thought-provoking study" – Nature
