“…However, ␣ 1 and ␣ 2 copies in gadids are clearly not related to their phylogenetic counterparts in members of clade X (zoarcoids and notothenioids). A specific perciform duplication of ␣ 1 and ␣ 2 copies is suggested between the emergence of gadiforms from the acanthomorph bush some 120 mya (52) and the emergence of the perciform clade X some 60 mya. Such duplication is independent from those leading to gadiform copies (see Fig.…”

The Arctic and Antarctic marine faunas differ by age and isolation. Fishes of the two polar regions have undergone different regional histories that have driven the physiological diversities. Antarctic fish are highly stenothermal, in keeping with stable water temperatures, whereas Arctic fish, being exposed to seasonal temperature variations, exhibit higher physiological plasticity. This study reports the characterization of the oxygen transport system of three Arctic species of the family Gadidae, namely the Arctic cod Arctogadus glacialis, the polar cod Boreogadus saida, and the Atlantic cod Gadus morhua. Unlike Antarctic notothenioids, the blood displays high multiplicity, i.e. it has three hemoglobins, similar to many other acanthomorph teleosts. In the most abundant hemoglobin, oxygen binding is modulated by heterotropic effectors, with marked Bohr and Root effects. Remarkably, in two species (A. glacialis and B. saida), the Hill coefficient is very close to one in the whole pH range, indicating the apparent absence of cooperativity. The amino acid sequences have been used to gain insight into the evolution history of globins of polar fish. The results indicate that Arctic and Antarctic globins have different phylogenies and lead us to suggest that the selective pressure of environment stability allows the phylogenetic signal to be maintained in the Antarctic sequences, whereas environmental variability would tend to disrupt this signal in the Gadidae sequences.The main differences between the Arctic and the Antarctic are the older age and longer isolation of the latter (1). The Antarctic has been isolated and cold longer than the Arctic, with ice-sheet development preceding that in the Arctic by at least 10 million years. In a recent review, Eastman (2) wrote the following. "The Antarctic experienced a slow and discontinuous transition from a warm-water system in the early Tertiary (15°C) to the cold-water system of today (Ϫ1.87°C). The first glaciation, including shelf-ice formation, had occurred 36 million years ago (mya) 2 in the early Oligocene. About 25 mya, the formation of the Polar Front, which followed the opening of the Drake passage, further isolated the Antarctic marine fauna from the world ocean. Although Europe began to separate from Greenland in the late Cretaceous, the exchange of Atlantic and Arctic waters through the passage between Greenland and the Svalbard islands was not possible until 27 mya. The Arctic region was in a high latitude position by the early Tertiary, but the climate remained temperate with water temperatures of 10 -15°C. Arctic land masses reached their present positions, and temperatures dropped below freezing during the Miocene about 10 -15 mya."The Antarctic and Arctic fish faunas differ in age, endemism (denoting species native to a given geographical area), and taxonomic diversity. In the southern ocean, the fauna includes 322 species grouped in 50 families (3), whereas the Arctic fauna has 416 species of 96 families. In the Antarctic, endemism reaches 88% and ris...
