Indeed, there exist numerous living organisms today, exhibiting all the relevant intermediate stages of eye evolution. Though to be far to Kevin_Levites, he did mention that the requisite apologetics have been repeatedly destroyed.
For example, various flatworms and some jellyfish possess simple photosensitive spots, and are only able to distinguish between light and dark - a feature that is also present in several protists. Other flatwoms exhibit the next stage - photosensitive cells in a cup shaped depression, allowing detection of directional shadows.
Then we have the “pinhole camera” eye, as seen in Nautilus, which facilitate precise directional sensing and even a limited degree of shape determination.
Then we have the completely enclosed eye, with a small forward opening and a transparent fluid contained within the eye, such as that seen in Onchyophorans, which is then followed by the appearance of enclosed eyes with a lens. Finally, separation of the lens from the front of the eye, and the development of a separate cornea and iris, as seen in modern vertebrates.
Then of course, Arthropods followed a different trajectory, with the development of compound eyes.
The fun part being, of course, that all of these different eye stage developments are controlled by the same set of genes, as I covered in this thread. A thread which our latest mythology fanboy clearly doesn’t even know exists.
Indeed, it’s notable that all the mythology fanboys who gatecrash this site to rail against evolution, have manifestly never learned even the elementary aspects of the topic. Instead, they have spooned up whatever lies were peddled on the subject on creationist websites, or drank whatever Kool-Aid was fed to them by their “holy men”, none of whom possess any proper scientific education.
Its a measure of the intellectual indolence that is endemic to mythology fanboyism, that none of the usual suspects ever bother to learn any genuine facts on the topic of evolutionary biology, instead operating as if the repeatedly destroyed canards they bring here with tiresome regularity constitute some ineffable brand of wisdom, instead of being rectally extracted tripe. The idea of reading an actual science textbook on the subject never occurs to them, let alone exerting the diligence require to peruse actual peer reviewed scientific papers.
Instead, they wallow in their smug, complacent wilful ignorance, pretending that people who spent decades engaging in proper scientific research know less than their tithe-fed “pastors”. Which is one of the reasons I adopt the “shock and awe” tactic of carpet bombing their drivel with whatever discoursive ordnance happens to be to hand - and after 14 years of collecting and reading genuine peer reviewed scientific papers, that’s a lot of ordnance.
