Cell Press Researchers reporting in the Cell Press journal Current Biology on April 17 have discovered little-known cave insects with rather novel sex lives. The Brazilian insects, which represent four distinct but related species in the genus Neotrogla, are the first example of an animal with sex-reversed genitalia. "Although sex-role reversal has been identified in several different animals, Neotrogla is the only example in which the intromittent organ is also reversed," says Kazunori...

Believed critical for determining which individuals can -- or cannot -- successfully reproduce with each other, genitalia not only figure prominently in the origin of new species, but are also typically the first type of trait to change as new species form. Today, new international research led by Indiana University shows that as populations and species diversify, the exact shape and fit of genitalia steals the show over size. In data gathered from populations isolated for less than 50...

UC researcher finds that when it comes to hooking up with the opposite sex, genital complexities do matter. Charles Darwin spent eight years studying barnacles and their genitalia. In much less time than that, University of Cincinnati evolutionary biologist Michal Polak (and co-author Arash Rashed, now at the University of California, Berkeley) have confirmed one of Darwin's theories: that genitalia complexities in some male species have developed because they assist the male in "holding her...

Female ducks have evolved an intriguing way to avoid becoming impregnated by undesirable but aggressive males endowed with large corkscrew-shaped penises: vaginas with clockwise spirals that thwart oppositely spiraled males. More details of this evolutionary battle of the sexes fought at the level of genitalia are described by Yale researchers in the December 23 issue of the journal Proceedings of the Royal Society B. "In species where forced copulation is common, males have evolved longer...
