A duplicated gene evolved into a switch that determines sex in frogs, revealing how evolution can safely reshape critical ...

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 ...

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 ...

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.

ISSAQUAH, Wash. — 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 ...

Tadpoles are to frogs as oranges are to apples. They are so very different, University of Cincinnati Professor Daniel Buchholz said. In his biology lab, he and his students are using a National ...
