Hey... Stuu, Sorry you are banned. I was enjoying our chat. Not sure if you can still read replies, but here goes anyways...
BTW... the 13th atom is specifically excluded in the article which says "scientists wondered why 7-cis-, 9-cis- or 13-cis- isomers could not achieve this goal,” Sekharan told PhysOrg.com."
What I had said was "Codes, where information is sent and received, ALWAYS have a code maker. (traffic signs, braille, language, etc) According to Bill Gates our DNA is the most sophisticated software in existence. "Stuu said:So, what evidence, and what logic demands that all codes need artificial coding?
If you want to get specific, it is vitamin A aldehyde. Retinal is a form of vitamin A.Stuu said:Not 'vitamin A'. It's specifically retinal.6days said:Light enters our eye 'hitting' rhodopsin, which consists of 2 molecules, the protein opsin which is integrated with vitamin A
The article says "yet for some reason photoreceptor cells only function with 11-cis-retinal'(the 11th atom)Stuu said:11-cis-retinal is not the only molecule that can respond with a shape-change to a single photon.6days said:the only possible way rhodopsin could become a light switch / chromophore was for the vitamin A molecule to change shape at a precise position, the 11th atom.
Bacteria do not have eyes that detect a single photon of light as we do making our light sensing capability, the absolute optimum...period.Stuu said:archaic bacteria use cis-trans isomerism of 13-cis-retinal as a proton pump system. So it's not only the conversion of the 11-double bond that is a useful shape-change chromophore system.
BTW... the 13th atom is specifically excluded in the article which says "scientists wondered why 7-cis-, 9-cis- or 13-cis- isomers could not achieve this goal,” Sekharan told PhysOrg.com."
Sure...The article says "Sekharan said. “This indeed is very surprising given the fact that, outside the protein environment, 11-cis-retinal is one of the least stable isomers." https://phys.org/news/2011-11-scientists-mystery-eye.html#jCpStuu said:Do you have a citation that demonstrates the surprise expressed by the original researchers, as you appear to be claim? Something that says 'we were surprised' that this least-stable system would be the one used?
Attributing perfection to natural selection is essentially the fallacy of begging the question. Since vitamin A aldehyde does not naturally exist in 11-cis-retinal how can natural selection, select it?? The OPTIMAL design is clear evidence of our omniscient Creator. "In the beginning..."Stuu said:But this is clearly an example of natural selection,...6days said:Perhaps part of the reason science keeps surprising evolutionists is we see amazing design, and evidence of our designer
