One of the most significant evolutionary events that occurred on Earth was the transition of water-dwelling fish to terrestrial tetrapods (four-limbed organisms with backbones). Fish probably originated in the oceans, and our first records of them are in marine rocks. However, by the Devonian P...
fish-tetrapod transitionsarcopterygianhumeripectoral musculatureThe humerus of Panderichthys has been considered to represent a transitional form between that of tetrapodomorph fish such as Eusthenopteron and tetrapods such as Acanthostega. The previous description was based on flattened material and was...

An important step towards understanding the evolution of terrestriality in vertebrates is to identify how the aquatic ancestors of tetrapods were able to access ground-based prey. We have discovered that the 'eel catfish' Channallabes apus, an inhabitant of the muddy swamps of tropical Africa, ...
40. The transition in scale conditions between stem-group and crown-group lineages remains unclear, particularly for features of osteichthyans commonly used to identify isolated scales. A lack of evidence from maxillate placoderms, which have been instrumental in resolving parallel problems for the ...
and proliferated from aquatic to terrestrial transition in tetrapods. Although previous studies indicated that TEs are important to genome evolution and could influence piscine adaptation to various habitats28, additional studies would be necessary to uncover the full function and evolutionary role ofCR1su...
However, to exploit these opportunities, tetrapods needed to see clearly on land. In their initial transition. their eyes built for underwater vision, would have been blurry and nearsighted. Furthermore. their corneas () needed to be moist for protection and oxygenation.The study focused on ...
