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, ...

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, ...

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 ...

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 ...

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 ...
