The Evolution of Vision System in Metazoan

Observing metazoan evolution of vision system is possible to find phisiologic inhibithors that avoid regeneration of tissue in adult form of some superior vertebrates. The adaptation of vertebrates to the various environment produces evolution strategy modifying the vision apparatus. It is interesting to verify that in some superior vertebrates not regenerate retina in adult form. This phenotipic expression is influenced by evolutive environment pressure.
