Okay, keep it simple, give me something that can be taken out and not be missed or a change you think it would be okay to make. remember, biological changes also have a chemical effect.
Ok. Wisdom Teeth. It would be better for humans if we didn't grow them. If I were a designer contracted to design humans, I could not justify the added expense of wisdom teeth when they rarely come in to serve any function, and if they do, they must often be surgically removed.
The recurrent laryngeal nerve. I would have a hard time justifying the extra material necessary to loop it around the aorta. That goes hextuple for giraffe design.
Pseudogenes. I would have left the vitamin C gene out, unless I felt my inventions would need vitamin C. Then I would have let it work.
Curvy backbone. When experimenting with the new "bipedal" gait, I might have kept the quadruped body plan while I worked out the ankles and knees. I would have re-engineered the vertebral column to accomodate bipedalism before I took my new bipedal models to market though.
Of course, I can't do any of this. I am not an all-powerful designer. Perhaps the all-powerful designer does look at design much differently than mere humans do. But if that is the case, arguments from design still fail. If the discipline of engineering and design is so radically different on the Omnipotent scale, then pretending to detect "design" in living beings without even knowing what "design" looks like is silly. If we
do detect design, then we are detecting design that is often sub-optimal. Whatever was available that could be rigged to make it work. Between bats and birds, one of them has a better designed wing. Between dolphins and swordfish, one has a better fin.
A common designer hypothesis does not predict these design "flaws."
With special pleading, a common designer can be stretched to
accomodate these flaws ("they are only flaws from our limited unknowing perspective")
Evolution predicts them and explains them elegantly and simply, with no special pleading. I hope you have read this whole thread. I hope you have read the thread started by choccy "evolution with no fossil record."
