Anti- evolutionary thinkers sometimes argue that natural selection could not produce a complex structure like the vertebrate eye.They claim that all of the parts of the eye must have arisen at once,asking why natural selection would favor the development of part of an eye that is not yet capable of forming a focused image.Which of the following statements is consistent with a survey of eye structure in the molluscs?

Question

Quizplus · Accepted Answer

A survey of eye structure in molluscs reveals that there are many intermediate stages of eye complexity, indicating that natural selection could favor the development of parts of an eye that are not yet capable of forming a focused image. This refutes the argument presented by anti-evolutionary thinkers. Option A is incorrect because the statement suggests that the vertebrate eye is completely different from the eyes found in molluscs, which is false. Option C is also incorrect because the vertebrate eye is not the ancestral form of the eye. Option D is also incorrect for the same reason as option A, and it is not true that only full-blown image-forming eyes are present in modern organisms.
