Question

A simple survey of natural organisms today shows a range of complexities of functioning eyes, from extremely simple/reduced eyespots and reflecting pigment cups, to the much more complex single-lens chambered eyes and compound eyes. What is problematical about considering the vertebrate single-lens chambered eye the "pinnacle of evolution"?

a. In terms of functionality, every form of the eye, from simple to complex, serves its required function.

b. From an engineering perspective, there are objective a number of objectively better or more complex eye designs than the vertebrate one.

c. Simple eyes could have arisen by chance alone but not more complex ones.

d. All of the above.

e. (a) and (b)

Answer 1

a. In terms of functionality, every form of the eye, from simple to complex, serves its required function.
b. From an engineering perspective, there are objective a number of objectively better or more complex eye designs than the vertebrate one.

Option a and b are correct. The eyes differs in their action. The complex eyes deals with the light arrangement direction etc to have a wider view. For nocturnal animals the complex eyes help to go with thier job. So the evolution of eye was based on their function. It was not about chance.
