One often cited argument from creationist is organ as complex as eye can’t be evolved by mere evolution, so eye must be designed from scratch. I would leave open the question how a designed eye compatible with other evolved organs. Unbeknown to most creationist is there are two ‘designs’ of eye, one which that the blood vessel is in front of the retina, another is which the blood vessel is behind the retina; it would leave to immense creativity of creationist to construe the argument why human being is endow with the later, thereby the inferior design? Why would the Almighty Christian God prefer jellyfish over human in the matter of eyesight?
My interest about eye design is not related to the enduring creationist-evolution debate, my interest is about the possibility of engineering a better eye for human being. Since we can transfer the gene from one species to another, why couldn’t we transfer the gene for manufacturing better designed eye from jellyfish to human gene pool? I don’t think anyone could find an argument against improve the eyesight of human as a species. What short term and long term disadvantage would a better eyesight confer to human being?
DNA-engineering offer human being an unique evolutionary advantage over other species: While other species have to use trial and error to find the gene most adapted to the existing environment which cost million animals their lives, human being can test-trial their idea of improvement pool in laboratory and inside computer. So what take other species a million years to develop, we as human only need to take a billion trial inside the computer(that is less than a hour in fast computer.)
So why not try this idea on human?
