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.

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 ...

African clawed frogs are known for their flat bodies, vocal organs and claws on the first three toes of the hind feet. Hamilton, ON, Dec. 16, 2024 – Researchers at McMaster University have uncovered ...
