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 ...

Genetic diversity is essential to the survival of a species. It’s easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

In the animal kingdom, reproduction is a necessary part of species survival. Parthenogenesis, a form of asexual reproduction where embryos develop from unfertilized eggs, has been observed in captive ...

When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered ...

Two captive female California condors each produced a chick asexually years ago – the only such instances ever recorded for that endangered species, researchers reported Thursday. And while this has ...

A shark born at Italy's Acquario Cala Gonone could be the first case of asexual reproduction in its species. The Sardinia-based facility says its female smooth-hound shark "Ispera" was born in a tank ...
