Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; ...

It is generally believed that sexual reproduction leads to fewer harmful genetic mutations than asexual reproduction. In their new study, Maldonado and his co-authors tested this theory by ...

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 ...

For nearly 130 years, traditional perceptions hold that asexual reproduction generates clone-like offspring and sexual reproduction leads to more diverse offspring. "In reality, however, the ...

In 2006, workers at two British zoos were shocked to find that their female Komodo dragons had given birth despite being isolated from males. One of them went on to mate with a male, showing how ...

An intriguing new theory of evolutionary biology says the reason sexual reproduction may be so successful is that it promotes genes that work well in combination with many other genes. This idea ...

This is not only of interest for pest control, but could also help answer a central question of evolutionary biology. ... “because asexual reproduction yields only genetically identical lines.

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 ...

At a recent meeting ('Evolutionary ecology and genetics of asexual reproduction', European Society for Evolutionary Biology, Åarhus, Denmark, August 2001), David Mark Welch called for more work ...

Jose Maldonado, a UTA doctoral student in biology, ... Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization by sperm.

Asexual reproduction would have created genetic clones of the parents. Bennett speculates this behavior is likely an evolutionary mechanism to better ensure the survival of their prodigy.
