Some dragonfish (Stomiidae) family members have rod opsins tuned to short-wave (blue) wavelengths, which is a very common adaptation found in deep-sea fish. However, other dragonfish species both emit and detect long-wave (red) emissions. Use maximum parsimony analysis along with the phylogenetic tree in Figurein order to deduce when red color vision was lost and/or gained. Figure
