s-Why would a common designer (God) who is so knowledgeable leave out the ability to synthesize vitamin C in both chimps and humans?
d-It could be due to the fallen state. That ability to synthesize vitamin C may have been lost. There is evidence that animals are degrading due to negative mutations as well. It's possible the same negative mutation occurred in Chimps as well as Humans. Guinea Pigs have also lost that ability.
When discussing science, "could be" is called a hypothesis. Evolution is a fact with a well supported theory explaining that observed fact. "Negative mutations" are eliminated from the population by natural selection.
In this case, chimps and humans had to compensate with behavioral dietary change to survive.
Does God think Chimps are in a fallen state? I don't think so.
d-God could have other reasons as well, but I don't know what those might be.
Yeah, well science has some pretty good explanations of how segments of DNA get cut. I didn't notice any Bible verses referring to vitamin C uptake.
d-Under evolutionary theory, you would thing that the ability to synthesize vitamin C would have been selected over not being able to. But that's not what we see. We see the loss of functionality.
No, sometimes things do not go towards progress. If a population can survive with compensating factors it does. Obviously, the elimination of vitamin C synthesizing gene
was compensated by dietary and behavioral changes.
Study parasites if you want to see evolution with loss of function. The parasites ability to survive was enhanced by not needing digestive systems or eyes etc.
Look at fish that have evolved in caves. Many of them are blind or don't have eyes at all. It is absurd to think God plucked their eyes out because of sin.
"Darwin clearly rejected Christianity and virtually all conventional arguments in defense of the existence of God and human immortality." In his own autobiography, Darwin admitted that his evolutionary beliefs gradually made the Bible unbelievable to him and said "Thus disbelief crept over me at a very slow rate, but was at last complete. The rate was so slow that I felt no distress, and have never since doubted even for a single second that my conclusion was correct. I can indeed hardly see how anyone ought to wish Christianity to be true."
Well, the animals clearly aren't immortal like man was. When man sinned, God cursed the earth. Thorns and thistles apparently weren't part of the original design. The animals aren't at the same level as man. God told Noah the animals were for food. Jesus, Himself, served other's fish and requested meat.
The animals aren't fallen, they were never created to be at a state where they could sin or fall from. They're food.
