For millions of years, some of Earth’s earliest animals barely changed. They lived, grew, and spread across the seafloor, but ...

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 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 ...

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

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 ...

Katherine Gallagher is a writer and sustainability expert. She holds a B.A. in English Literature from Chapman University and a Sustainable Tourism certificate from the GSTC. Parthenogenesis, a form ...

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 ...
