Oogamy: inventing the sexes.
The male-female dichotomy has evolved independently in nearly all lineages of multicellular organisms. Why this should be the case is still uncertain, but recent studies of mating-type genes in green algae open a promising new way to explore molecular-genetic aspects of the evolution of dichotomous sexes.
