Parthenogenesis, a form of asexual reproduction in which an egg develops in the absence of fertilisation, has traditionally been associated with invertebrates. However, recent discoveries have ...

The study revealed unexpected and sex-specific effects of germline regulation on longevity and somatic repair in vertebrates. Contrary to classical evolutionary theories, it turns out that changing ...

Researchers have found that germ cells, which develop into eggs and sperm, drive sex-dependent differences in lifespan in vertebrates. Female and male germ cells increase and reduce lifespan, ...

Sex is a tricky business, evolutionarily speaking. One problem is that sexually reproducing organisms must suffer the considerable faff of securing a mate (for the males of some species, the struggle ...

Reproduction is central to survival, but it may come at a hidden cost. In a new study, which drew on zoo records from more than 110 animals around the world, researchers found that blocking ...
