xplores the various methods of animal reproduction, highlighting the dependency of young animals on their parents, particularly in mammals, birds, and amphibians. It explains both asexual reproduction ...

In the framework of an international research project, a team of scientists have demonstrated for the first time that asexual reproduction can be successful in the long term. The animal they studied ...

The Amazon molly is an all-female fish that ditched sexual reproduction entirely, thriving for over 100,000 years through ...

In the course of evolution, animals have repeatedly shifted from sexual to asexual reproduction. The first evidence of the consequences of parthenogenesis – a type of asexual reproduction – on genome ...

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 common fruit fly normally needs a mate to reproduce. But scientists tinkering with its genes found the ones that can induce parthenogenesis, or virgin birth. For the first time, scientists ...

While scientists have previously observed “virgin births” in vertebrates such as sharks, rays and reptiles – a reproductive strategy thought to aid survival during periods of isolation – this is the ...

Why do animals engage in sexual reproduction? Biologists sought answers with mud snails that breed both sexually and asexually. They found that asexual snails grow faster and reach reproductive age ...

Sexual reproduction implies high costs, but it is difficult to give evidence for evolutionary advantages that would explain the predominance of meiotic sex in eukaryotes. A combinational theory ...
