This statement is completely false. We can see this, for example, in the mollusk family.
Child’s play. Didn’t you read the article? Complex eyes burst onto the fossil record, fully formed and fully functional. There is not evidence that they evolved. Showing pictures of different kinds of eyes or eye spots in the mollusk family, or any other family does not change this glaring fact, nor does it explain the complexity of these eyes. Surely you can do better?
PS Even from an evolutionary point of view, how do you know the eyes in your series didn’t degenerate (loss of information) from fully functioning eyes over time? Why do you assume everything is alway getting more complex?
