Curr Biol 16:R468-71. 2006..elegans and C. briggsae, however, produce self-fertile hermaphrodites instead of females. These transitions to hermaphroditism evolved convergently through distinct modifications of germline sex determination mechanisms...

- A role for genetic accommodation in evolution?Christian Braendle
Institut Jacques Monod, CNRS, Universités Paris 6 and 7, Paris, France
Bioessays 28:868-73. 2006..We argue that genetic accommodation, including assimilation, is a plausible mechanism in evolution; however, more work is required to test how this mechanism acts and how often it is involved in evolutionary change...
