Why, or more importantly, how, did sexual reproduction of life forms evolve?

It seems that this reproductive mechanism would be rather cubersome: two essentially different organisms of the same species come together to exchange genetic material and hope to see offsring into the next generation... single cell organisms seem to be a whole lot more efficient at reproduction by just cloning ... so how and why did nature "decide" to also include sexual reproduction mechanisms in the "fight for survival?" Dawkins ascribes this whole reproductive thing as DNAs way of maikng more DNA. ... So to be ultra-reductionist we are mere DNA making machines??...


Closing Statement from Lincoln Solomon

Closed out. And no conclusion. Some evolutionists postulate random selection of mutant genes and transfer of such between single celled organisms as the architypes of sexual reproduction as we observe it today. Creationists / ID folks believe in the design of a Creator. I have not been convinced, from this conversation, about the evolutionary mechanisms which gave rise to sexes and sexual reproduction methods.
Thanks for the input every-one. I Think I'll ask Google ...

    So you are saying sexual reproductive mechanisms predated multicellular organisms? SO unicellulars were doing it before the multies came along? Or did the multies derive from sexual reproduction?

      Feb 15 2013: not precisely. "horizontal" gene transfer predates. sexual reproduction is a variant of that.

      gene transfer -> multicellular reproduction with gene transfer -> separate sexes
