From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the ...

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, ...

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 ...

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 ...

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 ...

(Santa Barbara, Calif.) 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 ...

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 ...
