| Summary |
This book explores the current state of knowledge about microbial evolution under extreme conditions addressing questions from the perspectives of different extreme environments, organisms, and evolutionary processes: What is known about the processes of evolution that produce adaptations to extreme conditions? Can this knowledge be applied to other systems? What requires future research? |
