What is the basal Clade of amphibian?

The basal clade of amphibians is represented by the group known as "urodeles," or salamanders, which are believed to have diverged early in amphibian evolution. This clade includes some of the most primitive forms of amphibians, showcasing key evolutionary traits such as a dual life cycle, transitioning from aquatic larvae to terrestrial adults. Urodeles provide insights into the evolution of amphibian characteristics and adaptations. Additionally, their evolutionary history highlights the transition from water to land among vertebrates.
