Acquiring Genomes: A Theory Of The Origins Of Species by Lynn Margulis
English | June 19, 2002 | ISBN: 0465043917 | 256 Pages | DJVU | 3 MB
In this groundbreaking book, Lynn Margulis and Dorion Sagan present an answer to one of the enduring mysteries of evolution–the source of inherited variation that gives rise to new species. Random genetic mutation, long believed to be the main source of variation, is only a marginal factor. As the authors demonstrate in this book, the more important source of speciation, by far, is the acquisition of new genomes by symbiotic merger.
