How did we (living things in general) evolve 2 genders?

Considering that single celled organisms reproduce asexually and life as it currently exists ultimately began as single celled organisms, at what point during that evolution did life decide that having two "genders" would be more advantageous?

Note: OP didn't ask *why* having genders is advantageous. OP asked *how* life made the switch from asexual to sexual reproduction. Which I, too, would like to know. Can somebody answer the actual question?
