Symbiosis in cell evolution : microbial communities in the Archean and Proteroterozoic eons

Author: Lynn Margulis; L Margulis
Publisher: New York : W.H. Freeman and Company, 1993.
Edition/Format:   Print book : English : Second editionView all editions and formats
The monograph examines the evolution of microorganisms and the importance of symbiosis as a mechanism of evolution. Initial chapters discuss serial endosymbiosis theory, diversity, and cell evolution in perspective. The period from prebiotic times through the development of symbiosis is examined in chapters about the Earth before cells, evolution before oxygen, atmospheric oxygen from photosynthesis, and  Read more...

Contents: Part 1 Serial endosymbiosis theory: overview; autopoiesis and many genomes; origins; toward phototrophy; toward phototrophy; associations and eukaryotes. Part 2 Diversity: classification and evolution; prokaryotes and eukaryotes; five kingdoms. Part 3 Cell evolution in perspective: direct filiation; disreputable theories. Part 4 Before cells: the geological context; organic compounds; meteorites; making life in the laboratory. Part 5 Evolution before oxygen: criteria for relatedness; anaerobic innovations; the archean record. Part 6 Atmospheric oxygen from photosynthesis: aerobiosis in microbes; organic geochemistry; the proterozoic record and the earliest eukaryotes. Part 7 Symbiogenesis: symbiosis as parasexuality; from symbionts to organelles; mixotricha motility symbiosis; photosynthetic ciliates; predatory prokaryotes; genetic analysis of symbiodsis; names - binomial nomenclature and phylogenies for symbionts. Part 8 Nuclei, mitosis and undulipodia: nuclear origins; protoctist cell division; centriole-kinetosomes and microtubules; towards mitosis; centriole-kinetosome DNA. Part 9 Undulipodia from spirochetes: symbiosis and microtuble systems; spirochetes; preadaptive spirochete behaviour; motility symbioses; cytoplasmic tubules in prokaryotes; origins of undulipodia. Part 10 Mitrochondria: mitochondria from proteobacteria; mitochondrial legacy and cytoplasmic heredity; pathogen to organelle - a mitochondrial analogy; refining and interfacing - the mix-match princple. Part 11 Plastids: genetic continuity of plastids; plastid and host genomes; from symbiont to organelle - rare or frequent? Part 12 Phanerozoic consequences: calcium and skeletons; symbiogenesis, speciation and morphogenesis in the phanerozoic eon; plants, animals and chromosomes; gaia and the extant biosphere. Appendix Phyla and classes of the five kingdoms.
Responsibility: Lynn Margulis.


This second edition introduces evidence that symbiogenesis is a major source of evolutionary innovation leading to the origins of new species. The author offers insights into the genetic and  Read more...
