Additional genome duplication, specifically in ray-finned fish, may have occurred before the divergence of the teleosts.
This mounted skeleton of the common perch shows several characteristics of ray-finned fish.
While everyone knows that fish live in water and breathe through gills, the simile ‘like a fish out of water’ does not always apply to ray-finned fish.
Gliding is actually common among vertebrates; several reptiles, mammals, and even ray-finned fish have evolved gliding.
This finding is in accordance with the hypothesis of an ancient whole-genome duplication in the ray-finned fish lineage.
