I) Development of eye is not a point utilised in classification rather it is an important feature in the evolution. *Evolution of eye was not successfully explained by Darwin. It is the assumption made by the scientists that first eye-like structure could have been a light sensitive spot on the skin. This could have gone through many changes and complexities to form human eye. *There was a simplest light-sensitive spot on the skin in ancestral organisms. *Random changes created a depression in the light sensitive patch making the vision sharper.in animls like planarians *In insects, the light-sensitive spot gradually evolved into special layer with structures like ommatidia. *Later, over a period of time, lens was formed in front of the eye.*Vertebrates and octopuses developed the eye resembling a pin-hole camera. Nerve fibres pass infront of the retina. Cephalopods have an eyes in which nerves are attached to the retina. They do not have a blind spot. Blind spot is present in the retina of the vertebrate eye whereas blind spot is absent in the octopus eye. *Human eye is a complex structure made up of different structures which individually are incapable of vision. Altogether, the lens, the pupil, the iris and the retina make the vision possible.
