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 ...

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 ...

Reproduction in the animal kingdom has historically been sexual. Cloning the sheep Dolly in 1997 moved us closer to the possibility of duplicating other animals or humans asexually, but the practice ...

For most living things, sexual reproduction has proven the best overall strategy to perpetuate a species in the rough-and-tumble, unpredictable fray of natural selection. With two partners combining ...

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, ...

Why are most organisms sexual? The question of why most species reproduce sexually and others reproduce asexually has stymied biologists for years (particularly since asexual reproduction has many ...

A scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture. Farmers throughout the world spend ...
