| Abstract: | Background One of the greatest challenges facing the early land vertebrates was the need to effectively interpret a terrestrial environment.
Interpretation was based on ocular adaptations evolved for an aquatic environment millions of years earlier. The Australian
lungfish Neoceratodus forsteri is thought to be the closest living relative to the first terrestrial vertebrate, and yet nothing is known about the visual
pigments present in lungfish or the early tetrapods. |
