LYNN MARGULIS


///////////////ENDOSYMBIOTIC THEORY


/////////////////MONARCHY-MONOTHEISM-MONOPHYLY


////////////////In 1995, prominent evolutionary biologist Richard Dawkins had this to say about Lynn Margulis and her work:
“ I greatly admire Lynn Margulis's sheer courage and stamina in sticking by the endosymbiosis theory, and carrying it through from being an unorthodoxy to an orthodoxy. I'm referring to the theory that the eukaryotic cell is a symbiotic union of primitive prokaryotic cells. This is one of the great achievements of twentieth-century evolutionary biology, and I greatly admire her for it.[5]




////////////////he underlying theme of endosymbiotic theory, as formulated in 1966, was interdependence and cooperative existence of multiple prokaryotic organisms; one organism engulfed another, yet both survived and eventually evolved over millions of years into eukaryotic cells. Her 1970 book, Origin of Eukaryotic Cells, discusses her early work pertaining to this organelle genesis theory in detail. Currently, her endosymbiotic theory is recognized as the key method by which some organelles have arisen (see endosymbiotic theory for a discussion) and is widely accepted by mainstream scientists. The endosymbiotic theory of organogenesis gained strong support in the 1980s, when the genetic material of mitochondria and chloroplasts was found to be different from that of the symbiont's nuclear DNA.[4]




/////////////// Professor Margulis, who participates in hands-on teaching activities at levels from middle to graduate school, is the author of many articles and books. The most recent include Symbiotic Planet: A new look at evolution (1998) and Acquiring Genomes: A theory of the origins of species (2002), co-written with Dorion Sagan. Indeed, over the past decade and a half, Professor Margulis has co-written a number of books with Sagan, among them What is Sex? (1997), What is Life? (1995), Mystery Dance: On the evolution of human sexuality (1991), Microcosmos: Four billion years of evolution from our microbial ancestors (1986), and Origins of Sex: Three billion years of genetic recombination (1986). Her work with K. V. Schwartz provides a consistent formal classification of all life on Earth and has lead to the third edition of Five Kingdoms: An illustrated guide to the phyla of life on Earth (1998). Their evolutionary classification scheme was generated from scientific results of numerous colleagues. The logical basis for it is summarized in her single-authored book Symbiosis in Cell Evolution: Microbial communities in the Archean and Proterozoic eons (second edition, 1993). The bacterial origins of both chloroplasts and mitochondria are established. At present she works on the possible origin of cilia from spirochetes.
