Researchers have uncovered unexpected diversity in the genetic processes that determine the sex of the African clawed frog, a significant discovery in what was already one of the most widely studied ...

For more than half a century, studies on the African clawed frog (Xenopus laevis) have helped scientists better understand the biological underpinnings of life. Disclaimer: AAAS and EurekAlert! are ...

ISSAQUAH, Wash. (AP) — An invasive species is consuming and competing with native species in western Washington, including salmon. Scientists have spotted African clawed frogs in Issaquah, Lacey and ...

The development of hair was of central importance for the evolution of mammals and thus also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown.

African clawed frogs are masters of putting themselves back together, handily regenerating lost tails and hind limbs, when they are tadpoles. But these powers dim with maturity. Wait for an adult frog ...

While basically all frogs are semi-aquatic to some degree, some species spend nearly all of their lives underwater! Though they are quite rare, there are several notable varieties of nearly fully ...
