If the idea of living robots made out of frog cells isn't quite weird enough for you, how about living robots made out of frog cells with the ability to reproduce? These first-of-a-kind "Xenobots" are ...

A large-scale analysis of 117 mammal species found that preventing reproduction is associated with longer lifespans, suggesting a strong link between reproductive activity and life expectancy. Why do ...

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 ...

Why organisms began having sex, rather than simply reproducing asexually as life did for billions of years—and still does, in the case of single-celled organisms and some plants and fungi—is a bit of ...

For years scientists have known that some species of sharks, fish and lizards are capable of "virgin births," asexual reproduction known as parthenogenesis that occurs when unfertilized eggs develop.

In the animal kingdom, reproduction is a necessary part of species survival. Parthenogenesis, a form of asexual reproduction where embryos develop from unfertilized eggs, has been observed in captive ...
