How did sex evolve?
Simple single cell organisms simply split and reproduce. Pretty simple, and all self-contained.
Sex as we know it requires 2 versions of each specie with different, but complimentary "equipment" none of which is useful to the organism until all the pieces are present. Of what use are testes or a penis without the connecting ductwork?
