The study of early eukaryote evolution has changed drastically, with firm ideas being revised or abandoned after more sophisticated analyses of molecular sequence data. Organelles, Genomes and Eukaryote Phylogeny reviews the field of "deep level" phylogenetic inference of eukaryotes, especially regarding the origin and evolution of eukaryotic cells and their organelles. By interpreting data from molecular and cell biology, genome sequencing with respect to eukaryogenesis, and endosymbiotic events leading to mitochondria and plastids, this book proves relevant to all postgraduates and professionals in molecular systematics, comparative genomics and cell biology.
