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 ...

Researchers at McMaster University 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 ...

Early in development, many animals pick a team—male or female—based on their genetics, and, with time, acquire the ...

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 ...

Very occasionally, African clawed frog tadpoles never stop being tadpoles and turn into frogs. They increase in size, and they reach a form of sexual maturity, but they look eternally young. And then ...

A group of scientists used drug treatments to regrow legs on African clawed frogs in 18 months. While tadpoles and froglets can regenerate their body parts, adult African clawed frogs can't. Humans ...
