Fishes invaded and ruled the oceans and fresh waterways during 500 million years of evolution, finally emerging onto land, albeit briefly. Major clades thrived and then died out or were supplanted by other groupings with supposedly greater advances. The transition from hagfish to finned fish is a lengthy and complicated process.The cyprinid fish (8mm) and the whale shark (12m) are some of the smallest and largest fish in the sea. At first, this might seem like an easy question to answer, but it is difficult to define what makes a fish a fish because there is so much diversity among animals that we consider to be fishes.

Flying fish can glide over the surface of the ocean because of adaptations in their body proportions. Surprisingly few genetic changes were needed for these adaptations. [email protected] bowfin (Amia calva) is a ray-finned fish that possesses a unique suite of ancestral and derived phenotypes, which are key to understanding vertebrate evolution. The phylogenetic position of ...To provide for a more robust hypothesis of osteichthyan phylogeny and more accurate times of diversification, we conducted the first comprehensive analysis of bony fish evolution.

The first species to be classified as fish were soft-bodied chordates during the Cambrian Period.

Fish - Evolution, Paleontology, Adaptation: The earliest vertebrate fossils of certain relationships are jawless fishes (superclass Agnatha, order Heterostraci) from the Upper Ordovician. The next class of fishes to appear were jawed vertebrates of the Acanthodii, which arose in the Late Silurian.Fish evolution and the development of air-breathing did not end with the appearance of the first amphibians, but has continued to the present day. Air-breathing in fish is the process of aerial gas exchange for respiration and requires an air-breathing organ.Fish - Evolution, Paleontology, Adaptation: The earliest vertebrate fossils of certain relationships are jawless fishes (superclass Agnatha, order Heterostraci) from the Upper Ordovician. The next class of fishes to appear were jawed vertebrates of the Acanthodii, which arose in the Late Silurian.This ultimately supports a fish-mammal evolution, as implied by the title of Shubin’s work. Shubin proceeds to support evolution by comparing characteristics of humans with that of phylogenetically older species. Embryology provides evidence for Shubin. All animals with skulls share something developmentally.
