How did macroevolution occur? This important question, which has remained unanswered since Darwin, continues to be a mystery even now that many genomes have been decoded. Big transitions, like genome-level duplication, often result in little change in appearance of the organism. Instead, even small-scale but significant qualitative changes have brought about major evolutionary transitions. It is well-known that the genes involved in the birth of the eye are thought to have led to the dramatic diversification of multicellular organisms, for instance. In this symposium, we would like to propose active discussion on this kind of qualitative change, or "genome epochs."
