LIFE’S PULSES: From Origins to Mammals

Life's Pulses: From Origins to Mammals presents a new way of viewing the history of life. Rather than tracing evolution through a conventional linear timeline, the author applies a logarithmic framework in which major evolutionary innovations appear as a series of progressively halving intervals. Within this framework, evolutionary transitions are examined through "Major Nodes" and surrounding precursor and explicit phases, allowing evidence from paleontology, molecular biology, geology, and evolutionary theory to be compared in a unified temporal model.

This first volume follows the opening five pulses of life's history: the origin of life, the emergence of eukaryotic cells, the rise of developmentally complex multicellularity, the appearance of vertebrates, and the evolution of mammals. Each chapter combines current fossil discoveries, molecular-clock evidence, and ecological context to explore when major grade-level changes occurred and how they transformed the biosphere.

Written for readers interested in evolution, paleontology, the history of life, and interdisciplinary science, Life's Pulses offers an original synthesis of contemporary research while inviting readers to consider whether life's greatest transitions reveal an underlying temporal pattern. This volume concludes at the ecological expansion of mammals, preparing the way for a second volume devoted to the primate pulses that culminate in the emergence of humanity.
