Creationism predicts genetic entropy in nature, which means the DNA for humans was much better with the ancients than it is today while evolution predicts gains in function with the purpose of enhancing fitness. There was a study recently with Vitamin C which is interesting, because humans have lost the ability to manufacture it, so it must be obtained through a diet. And we are not the only ones, certain bats, and certain birds, some fish, guinea pigs and anthropoid have also lost the ability to manufacture Vitamin C.
The study was focused on why this has happened, in PLoS they say, “The ability to synthesize Vc has been reported in many ancestral vertebrate lineages, suggesting the ability for de novo synthesis is ancient.” Nowhere in the paper do the authors explain for the most part on how Vc emerged in the first place such as gains in function within various transitional forms. Rather, the paper mentions quite a bit on loss of function.
“Interestingly, ancestral sequence reconstruction exhibits a stepwise mutation pattern (figure 4) that starts around the time when the tested bat species first evolved from a common ancestor around 58 mya.”
“The ancestor of all bats maintains most of the original Laurasiatheria gene form (with only two mutations) after divergence with non-bat Laurasiatheria species; the ancestor of Hipposideridae, Rhinolophidae, and Megadermatidae (origin around 52 mya) has 3 mutations; the ancestor of Hipposideridae and Rhinolophidae (origin around 39 mya) has 4 mutations; the ancestor of Pteropodidae (origin around 23 mya) has 7 mutations; and the ancestor of the recently emerged Pteropus bats (around 3 mya) have 13 mutations, hence showing a stepwise accumulation of mutations during bat GULO evolution.”
They assume the evolutionary dating, but all this is showing is how many mutations a species had rather than gains that transforms the animal into a bat, what they are showing is the number of mutations with loss in function. Is this really evolution? Wouldn’t it be better for the body to already have the supplement instead of having to obtain it through diet? If any thing, the prediction of evolution would be the other way around. All this study consists of mutations taking away function. Their answer, well the humans and animals can eat, so it wasn’t necessary to manufacture the supplement. It is interesting to note, the paper mentions, “the ancestor of all bats” but there is no common ancestor of bats! They just assume it because where is it? The oldest bat fossil is one hundred percent bat!
In another study from last year, Peter A. Lind, Otto G. Berg, and Dan I. Andersson from Uppsala University conducted an experiment on Salmonella bacterium which was published in the journal of science in November 2010. Their focus here was to come up with new insights on how evolution increases fitness. What surprised evolutionists about this experiment, the mutations caused a loss in fitness rather than an increase in fitness which also confirms the creationist prediction of genetic entropy in nature!
In another paper in Nature, “Experimental evolution reveals resistance to change” where it says…
“Experimental evolution systems allow the genomic study of adaptation, and so far this has been done primarily in asexual systems with small genomes, such as bacteria and yeast. Here we present whole-genome resequencing data from Drosophila melanogaster populations that have experienced over 600 generations of laboratory selection for accelerated development.” We conclude that, at least for life history characters such as development time, unconditionally advantageous alleles rarely arise, are associated with small net fitness gains or cannot fix because selection coefficients change over time.”
Science continues to confirm genetic entropy in nature and scientists are now taking a look at on how they they could restore the body being able to make Vitamin C again. “The gene encoding GULO in guinea pigs and humans has become a pseudogene.” Wouldn’t that be great? No more having to ingest Vitamin C anymore!
