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, ...

A study has found that the reason why the evolution of the first animals to appear on Earth was delayed for over 10 million ...

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 ...

The way that Earth's first animals reproduced held back life's diversity for millions of years, until stress and competition ...

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 ...

A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those ...

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 ...
