The origin of tetrapods and their invasion of the land during the Devonian period was one of the most significant events in vertebrate evolutionary history. Understanding the environmental circumstances and the morphological and functional changes underlying the fish‐tetrapod transition have been goals of comparative biologists for many decades. Although the fossil record of this transition remains far from complete, new discoveries in the past two decades have increased the resolution of the… 

Adaptations of amphibious fish for surviving life out of water

There are a small number of fish species, both marine and freshwater, that exhibit a truly amphibious habit that includes periods of aerial exposure and the more amphibious fish are more adapted to moving on land and seeing in air.

This review summarizes major advances made and reevaluates alternative interpretations of important parts of the evidence of the fish‐tetrapod transition, and discusses each of these steps with respect to inferred functional utility of acquired character sets.

Proposed habitats of early tetrapods: gills, kidneys, and the water–land transition

It is suggested that the apparent loss of the gills in tetrapods more derived than Acanthostega signals their descent from a more terrestrial phase in Tetrapod evolution, following the primary assumption by the kidney of the excretion of nitrogenous wastes.

Invasions of the land : the transitions of organisms from aquatic to terrestrial life

This text provides a general overview of how plants and animals made the transition from water to land, and incorporates the latest information relevant to water-land transitions, deriving from recent applications of micropalaeontological and molecular methods to classical issues.

Breathing Air in Air: In What Ways Might Extant Amphibious Fish Biology Relate to Prevailing Concepts about Early Tetrapods, the Evolution of Vertebrate Air Breathing, and the Vertebrate Land Transition?*

It is argued that selection pressures imposed by life in the intertidal zone are insufficient to have resulted in the requisite aerial respiratory capacity or the degree of separation from water required for the vertebrate land transition.

The Concept of Monophyly: A Speculative Essay

The concept of monophyly is central to much of modern biology. Despite many efforts over many years, important questions remain unanswered that relate both to the concept itself and to its various

The Origin and Evolution of the Surfactant System in Fish: Insights into the Evolution of Lungs and Swim Bladders*

This study presents new data on the surfactant system in swim bladders of three teleost fish and demonstrates the first demonstration of the presence of SP‐D in the air‐breathing organs of nonmammalian species and SP‐B in actinopterygian fishes.

Beach‐Spawning Fishes, Terrestrial Eggs, and Air Breathing*

This work considers beach spawning a form of parental care in fishes, where the adults place eggs so they will be emerged into air during part or all of incubation, providing increased temperatures, oxygen availability, and protection.

Did lungs and the intracardiac shunt evolve to oxygenate the heart in vertebrates?

This paper presents a new hypothesis for lung evolution that is more consistent with the fossil record and physiology of extant animals than the traditional scenario; it is proposed that lungs evolved to supply the heart with oxygen.

Five Tropical Air‐Breathing Fishes, Six Different Strategies to Defend against Ammonia Toxicity on Land*

Modern tropical air‐breathing fishes exhibit a variety of strategies to survive on land, and they represent a spectrum of specimens through which various biochemical adaptations that would have facilitated the invasion of the terrestrial habitat by fishes during evolution are examined.

Patterns and Processes of Vertebrate Evolution

This chapter discusses the evolution of non-Mammalian Vertebrates in the Late Cenozoic and the influence of systems of classification on concepts of Evolutionary Patterns.
