摘要

The origin of land vertebrates was one of the major transitions in the history of vertebrates. Yet, despite many studies that are based on either morphology or mole- cules, the phylogenetic relationships among tetrapods and the other two living groups of lobe-finned fishes, the coelacanth and the lungfishes, are still unresolved and debated. Knowl- edge of the relationships among these lineages, which origi- nated back in the Devonian, has profound implications for the reconstruction of the evolutionary scenario of the conquest of land.
