In Search of Cell History examines the evolution of cells and addresses fundamental questions about the definition of life and cellular organization. The origin of cells remains one of biology's most fundamental mysteries, and this book offers a comprehensive overview of the research and ongoing debates in the field. Written in accessible language with a glossary for reference, the book explores the relationship between cells and genes, the role of bioenergetics in the origin of life, the universal tree of life with its three stems and viral outliers, and controversies surrounding the last universal common ancestor. Harold also discusses the evolution of cellular organization, the origin of complex cells, and the incorporation of symbiotic organelles. The book demonstrates current understanding of cell evolution and the evolution of life in general, while acknowledging the significant questions that remain unanswered in the field.
