Symbiosis as a Source of Evolutionary Innovation

<b>These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis supplemented by the gradual accumulation of heritable mutation results in the origin of new species and morphological novelty.</b><p>A departure from mainstream biology the idea of symbiosis--as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals--has attracted the attention of a growing number of scientists.</p><p>These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis supplemented by the gradual accumulation of heritable mutation results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution microbial symbioses animal-bacterial symbioses and the importance of symbiosis in cell evolution ecology and morphogenesis. Lynn Margulis Distinguished Professor of Botany at the University of Massachusetts at Amherst is the modern originator of the symbiotic theory of cell evolution. Once considered heresy her ideas are now part of the microbiological revolution. </p><p><b>Contributors<br></b>Peter Atsatt Richard C. Back David Bermudes Paola Bonfante-Fasolo René Fester Lynda J.
