  text: 'The evolution of assortative mating is a key part of the speciation process.
    Stronger assortment, or greater divergence in mating traits, between species pairs
    with overlapping ranges is commonly observed, but possible causes of this pattern
    of reproductive character displacement are difficult to distinguish. We use a
    multidisciplinary approach to provide a rare example where it is possible to distinguish
    among hypotheses concerning the evolution of reproductive character displacement.
    We build on an earlier comparative analysis that illustrated a strong pattern
    of greater divergence in penis form between pairs of sister species with overlapping
    ranges than between allopatric sister-species pairs, in a large clade of marine
    gastropods (Littorinidae). We investigate both assortative mating and divergence
    in male genitalia in one of the sister-species pairs, discriminating among three
    contrasting processes each of which can generate a pattern of reproductive character
    displacement: reinforcement, reproductive interference and the Templeton effect.
    We demonstrate reproductive character displacement in assortative mating, but
    not in genital form between this pair of sister species and use demographic models
    to distinguish among the different processes. Our results support a model with
    no gene flow since secondary contact and thus favor reproductive interference
    as the cause of reproductive character displacement for mate choice, rather than
    reinforcement. High gene flow within species argues against the Templeton effect.
    Secondary contact appears to have had little impact on genital divergence.'
