Understanding Evolution

A Fisheye View of the Tree of Life

Phylogeny of the ray-finned fishes

This evolutionary tree shows relationships among all major clades of the Actinopterygii (ACK-tih-NOP-tuh-RIJ-ee-eye), or ray-finned fishes, as well as the diversity of those groups. The phylogeny shown here was based on the best evidence available in 2010. However, if new evidence is discovered, scientists may revise their views of evolutionary relationships. See an interactive fish phylogeny based on the evidence available in 2013.
