In an early post John, who wants to be called doctor, urged readers to take a look at a little paper by Dan Nilsson and Suzanne Pilger. He says it is a good conceptual example of how natural selection acting on variation can gradually create a new feature.
Gee, that must be quite a paper. He says it can’t be beat! So what does their paper actually show? The paper is called , “A Pessimistic Estimate of the Time Required for an Eye to Evolve.” Well, that does sound interesting!
A light sensitive patch will gradually turn into a focus lensed eye in 100,000 years. But of course they are using a pessimistic estimate, probably would happen even faster! Wow.
In fact the paper is written in such a way as to make many people falsely believe that Nilsson and Pilger had come up with a computer model to show the steps of eye evolution, from “random” mutations. Now that is something.
But because they didn’t ACTUALLY make any computer model (who has time) the task was made much easier for Nilsson and Pilger. Just take an eye, unfold all the pieces, and put them back together, one step at a time. POOF! (Yes Patrick, that is a poof!). But let’s make it even easier, because well, time, and let’s start with light sensitive cells. Then just poof in a depression where the light sensitive cells are. Next poof in another, deeper impression. That sure does help focus the light doesn’t it? Let’s keep that mutation!
From there we can just keep poofing away. Fill the cavity with fluid. Poof in a lens. Make the lens better. Poof in some rods and cones. All at random mind you. Make them better…Keep those mutations (don’t let them mutate themselves, because they won’t help building an eye at all!) Rudyard Kipling would be so proud.
This fable has already been passed down to generations. Take a look, these brilliant scientist doctors say, an eye is not so hard after all. If only Darwin had known Nilsson and Pilger he never would have had reason to doubt himself. Its as easy as POOF!
Of course John is apparently intimidated to engage with people who actually challenge him . So what do you think?
