For many years it has been suggested that sexual isolation caused by differences in mating behaviours is a precursor for reproductive isolation (lack of gene flow), and consequently speciation, in nature. Mate choice behaviours are thought to be important forces that can result in speciation events because the strength of selection for attractive traits is often very strong.
