Origin of Eukaryotic Cells: Evidence and Research Implications for a Theory of the Origin and Evolution of Microbial, Plant, and Animal Cells on the Precambrian Earth

The Origin of Eukaryotic Cells is a book published in 1970 by biologist Lynn Margulis, where she presented her groundbreaking theory that eukaryotic cells, the complex cells found in plants and animals, originated through a process called endosymbiosis, where smaller prokaryotic cells were engulfed by other cells and evolved into organelles like mitochondria and chloroplasts within the larger cell.
