Two supposedly asexual species of stick insects may engage in occasional bouts of sex, helping to widen their gene pool and avoid harmful mutations. A handful of animals reproduce asexually, primarily ...

Stick insects that reproduce asexually cannot adapt as quickly in the course of evolution as sexually reproducing species, leading to a decrease in biological diversity, according to new research. An ...

The evolution of sex remains one of biology's greatest puzzles. While sexual reproduction dominates across the animal kingdom, scientists still debate why it persists despite its high costs. Even more ...

Do Rare Males Retain Reproductive Function? While most animals reproduce sexually, some species rely solely on females for parthenogenetic reproduction. Even in these species, rare males occasionally ...

How does evolution move from conventional sexual reproduction to asexuality without males? A new study by researchers from the Universities of Lausanne, Lund and Rostock reveals that this remarkable ...

An international research team has shown that parthenogenesis, a form of asexual reproduction, negatively affects the genome evolution of the animals that practice it. In this type of reproduction, ...
