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, ...

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 ...

Thousands of species produce genetically identical (clonal) offspring through asexual reproduction 1. However, asexual reproduction is much less common than sexual reproduction is, partly because it ...

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 ...

The reason why, in terms of evolution, organisms have sex may seem rather obvious – they do it to reproduce. Clearly, natural selection must favour individuals who can reproduce over those who can’t.

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 ...
