title: Evolution of sex: mating rituals of a pre-metazoan.
abstract: Sex is pervasive throughout eukaryotes, yet many species have not been caught in the act. Now, a sexual cycle has been discovered in the choanoflagellate Salpingoeca rosetta, a pre-metazoan evolutionary model, opening a window on metazoan sexual evolution.
