Best Answer
Ans. The eyes seen in planaria, insects, octopus and vertebrates vary greatly in their structure. These organisms can be used for studying evolution of eyes as the eyes of planaria are simple without lens, insects have compound eyes and vertebrates have highly specialized eyes. However, all of them perform the same function, that is, vision. Thus, a common evolutionary origin can be established.
