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 African clawed frog is used as a model organism for biological research because of its close evolutionary relationship to humans, and because early development occurs externally, allowing ...

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 ...

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.

More than 6,000 virus-infected African clawed frogs were euthanized over the summer in a Washington State pond, The Olympian reported. The frogs are predatory, invasive and reproduce quickly. A ...
