Genomic sequencing of non-bilaterian animal phyla and their closest non-metazoan relatives has provided invaluable insight into the molecular innovations that have fueled the outbreak of diversity and complexity in the early evolution of animals.

Biol. 24, R951R952 (2014). A number of studies on Mnemiopsis have led to a better understanding of many key biological processes, including regeneration and axial patterning, and these studies have contributed to the emergence of Mnemiopsis as an important model for evolutionary and developmental studies. The authors declare no competing interests. The most likely cause of its introduction is accidentally by merchant ships' ballast water. They have gonads that contain the ovary and spermatophore bunches in their gastrodermis. Present address: Department of Human Genetics, University of Utah, Salt Lake City, UT, USA.
