In a seminal paper, Hammerstein and Parker (1987) described how sex roles in mate searching can be frequency dependent: the need for one sex to perform mate searching is diminished when the opposite sex takes on the greater searching effort.

The conventional view of promiscuous, undiscriminating males and coy, choosy females has als...
