title: Oogenesis: making the mos of meiosis.
abstract: Meiosis is an ancient type of cell division whose advent allowed the evolution of sexual reproduction. The evolutionary history of the specialization that allowed gamete production to emerge from a simple reduction division has been unclear. New data now suggest that the molecular mechanisms involved in animal oocyte specialization may have origins that predate the emergence of bilaterian animals.
