Genital coevolution between the sexes is expected to be common because of the direct
interaction between male and female genitalia during copulation. Here we review the …

Sperm competition is a powerful selective force that has shaped sexual traits throughout
animal evolution. Yet, how fertilization mode (ie external versus internal fertilization) …

The evolution of the placenta from a non-placental ancestor causes a shift of maternal
investment from pre-to post-fertilization, creating a venue for parent–offspring conflicts …

Female genitalia have been largely neglected in studies of genital evolution, perhaps due to
the long‐standing belief that they are relatively invariable and therefore taxonomically and …

The fish subfamily Poeciliinae (sensu Parenti, 1981) is widely distributed across the Western
Hemisphere and a dominant component of the fish communities of Central America …

Many fields of biology—including vertebrate Evo‐Devo research—are facing an explosion of
genomic and transcriptomic sequence information and a multitude of fish species are now …

The mechanisms underlying sex determination are astonishingly plastic. Particularly the
triggers for the molecular machinery, which recalls either the male or female developmental …

The brain is one of the most energetically expensive organs in the vertebrate body.
Consequently, the energetic requirements of encephalization are suggested to impose …

Background Sexually dimorphic phenotypes are generally associated with differential gene
expression between the sexes. The study of molecular evolution and genomic location of …

Kuhn [1] recognized that scientific advances are made through periods of 'normal
science'and 'revolutionary science'. During periods of normal science researchers explore …
