The Antagonistic Co-evolution of Duck Genitalia
Explores the complex reproductive anatomy and mating behaviors of ducks, highlighting how they differ from other birds often described as “lovebirds.” Unlike most birds, which engage in a “cloacal kiss” for reproduction, male ducks have penises that can be relatively large and corkscrew-shaped, with size varying seasonally.
It also explains the phenomenon of antagonistic co-evolution, where males’ aggressive mating strategies have driven females to develop equally intricate, twisty vaginas with dead ends to prevent forced insemination. This evolutionary “arms race” demonstrates how sexual selection can produce extreme physical traits and behaviors, contrasting sharply with the gentler courtship practices of species like swans or penguins.
