Morphological diversity in the orbital bones of two teleosts with experimental and natural variation in eye size

摘要

Background: Understanding differences in tissue morphology has not been well researched, yet provides crucial insight into evolution. We investigate the effect of eye reduction on the shape of surrounding bones by examining two morphs of the Mexican tetra (Tinaja cavefish and sighted fish), F1 intermediates, zebrafish, a sighted tetra after lens removal and a zebrafish mutant, bum(-/-), which has a degenerating lens.
