Abstract: The evolution of eyes in different phyla from the structure and gene level was studied. The structure, function and further evolution of the primitive eye shared by different phyla were also discussed. Based on the idea of natural selection, it cascaded the eye structure of arthropoda, mollusca and chordate, which have the most prominent eye structure, to reveal the evolution process of the eye from the primitive structure to the complex structure and possible promoting factors. Focusing on the functions as well as the advantages and disadvantages of different eyes, the diversity and the convergence of eye structure in different phyla were analyzed. The possible causes of diversity and convergence were explained. This study revealed the basic logic of biological evolution and provided a new research idea for evolutionary research.

Key words: eyes, evolution, structure, diversity, consistency
