The evolution of fish began about 530 million years ago during the Cambrian explosion.

The Devonian period 419–359 Ma (Age of Fishes) saw the development of early sharks, armoured placoderms and various lobe-finned fishes including the tetrapod transitional species. The evolution of fish began about 530 million years ago during the Cambrian explosion.

Ostracoderms ( lit. 'shell-skins') are the armored jawless fish of the Paleozoic Era. The term does not often appear in classifications today because it is paraphyletic (excluding jawed fishes) (may also be polyphyletic if anaspids are closer to cyclostomes) and thus does not correspond to one evolutionary lineage. [1]

Through evolution, one branch of fish preserved the lung functions that are more adapted to air breathing and ultimately led to the evolution of tetrapods. The other branch of fishes modified the ...The discovery of a 410-million-year-old fish fossil with a bony skull suggests the lighter skeletons of sharks may have evolved from bony ancestors, rather than the other way around.

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.
