Opis

This volume is a collection of the some of the most significant lectures that well-known experts presented at our two international "summits on evolution" (2005, 2009) as updated and revised chapters. The meetings took place on one of the large islands of the Galapagos archipelago (San Cristobal) at GAIAS (Galapagos Institute for the Arts and Sciences) of the Universidad San Francisco de Quito (USFQ), Ecuador.​ The main goal of the two Galapagos Summits on Evolution has been to bring together scientists and graduate students engaged in the study of evolution, from life's origin to its current diversity. Because of their historical significance, the Galapagos are a unique venue for promoting comprehensive research on evolution and ecology and to make the research results available to students and teachers everywhere, but especially from developing countries. As shown by the enthusiastic attendance at both summits and the many suggestions to keep them continuing, the meetings have opened new opportunities for students from Ecuador and other Latin American countries to be inspired by some of the most brilliant minds in evolutionary science.

In 2001 Lynn Margulis visited the main campus of the Universidad San Francisco de Quito to give the commencement address and to travel to the Tiputini Biodiversity Station in the Ecuadorian Amazonia.  We felt privileged to be part of her entourage for this trip to the rainforest and to have the opportunity to listen her descriptions of hundreds of plants, fungi, insects, slime molds, and even symbiotic protists inhabiting the guts of primitive termites.  During this trip Lynn expressed the need to promote a more comprehensive perspective on biological evolution, one that takes in account not only the classical and modern interpretations of Darwin’s ideas but also the mechanisms of microbial evolution, especially  symbiogenesis -the process that gave rise to eucaryotes  more than two billion years ago and has continued to shape protists and  multicellular organisms ever since.  It was clear that evolutionary science was concentrated primarily on macroscopic biota while neglecting microbes almost entirely.     

Those conversations became the main motivation to bring some of the most important minds working in evolutionary science to the very place that inspired Charles Darwin, the Galapagos Islands. During  the summers of  2005 and  2009 we gathered scientists specializing on plants, animals, bacteria and, protists to discuss the peculiarities of evolutionary mechanisms within each domain of life. This book contains some of the most important lectures presented at the first two World Summits on Evolution.
