Description
This evolutionary diagram shows how these 4 fish can be distinguished through certain characteristics. Using these characteristics, we can follow the diagram to see which fish are related to each other by the number of traits they shared. A large amount of shared traits imply that these two fish share a common ancestor and have evolved from each other.
