| 摘要 | Lungfishes, the closest living relatives of land vertebrates, have a long and conservative evolutionary history that began over 415 million years ago (mya) in the Early Devonian.1-3 Morphological gaps between the earliest known and most primitive lungfish, Diabolepis, and the more derived members of the group (Eudipnoi) hinder a comprehensive understanding of key evolutionary transformations near the onset of this lineage.1 A few early eudipnoans from the Pragian (similar to 410 Ma),4-7 such as Uranolophus from Wyoming, USA,8,9 have been thought to fill this gap, but their fossils are too flattened to reveal internal structures like the braincase.8-11 Here, we describe a new eudipnoan from the Pragian of China, whose skull is exceptionally well preserved, allowing us to study the inside of the head in detail for the first time in such an early lungfish. The new species has a palate similar to Uranolophus but also retains several features seen in Diabolepis. Phylogenetic and tip-dating Bayesian analyses place it at the base of the eudipnoan lineage, suggesting that lungfishes evolved rapidly during their early history. The discovery also points to connections between South China and North America during the Early Devonian. Altogether, this find helps clarify how early lungfishes developed key features that later shaped the group known today as the "living fossils.''12-14 |
