The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys. During the late Cambrian, eel-like jawless fish called the conodonts, and small mostly armoured fish known as ostracoderms, first appeared. Most jawle… WebThe evolutionary tree shown here focuses on relationships among the ray-finned fishes (Actinopterygii, ACK-tih-NOP-tuh-RIJ-ee-eye). Click on the colored logos to read about …
