Following are excerpts from an article published in Scientific American which originally contained heavy deep-time fish-to-men evolution language. When we take the actual findings and remove the secular atheistic bias we clearly see how easily this can be attributed to creationism and intelligent design. In fact, given the clear benefits outlined in this article, common sense dictates the arrival to the obvious conclusion... God did it!
Read the original article here and then compare with the following.
The use of [...] indicates where evolutionary language was removed without any damage to the integrity of the findings themselves.
Scientists think that they have the answer to why the skin on human fingers and toes shrivels up like an old prune when we soak in the bath. Laboratory tests confirmed a theory that wrinkly fingers improve our grip on wet or submerged objects, working to channel away the water like the rain treads in car tires.
People often assume that wrinkling is the result of water passing into the outer layer of the skin and making it swell up. But researchers have known since the 1930s that the effect does not occur when there is nerve damage in the fingers. This points to the change being an involuntary reaction by the body's autonomic nervous system — the system that also controls breathing, heart rate and perspiration. In fact, the distinctive wrinkling is caused by blood vessels constricting below the skin.
In 2011, Mark Changizi [...] showed that the pattern of wrinkling appeared to be optimized for providing a drainage network that improved grip. But until now, there was no proof that wrinkly fingers did in fact offer an advantage.
In the latest study, participants picked up wet or dry objects including marbles of different sizes with normal hands or with fingers wrinkled after soaking in warm water for 30 minutes. The subjects were faster at picking up wet marbles with wrinkled fingers than with dry ones, but wrinkles made no difference for moving dry objects. The results are published today in Biology Letters.
"We have shown that wrinkled fingers give a better grip in wet conditions — it could be working like treads on your car tires, which allow more of the tire to be in contact with the road and gives you a better grip," says Tom Smulders, a [...] biologist at Newcastle University, UK, and a co-author of the paper.
Changizi says that the results provide behavioral evidence "that pruney fingers are rain treads", which are consistent with his own team's [...] findings. What remains to be done, he adds, is to check that similar wrinkling occurs in [...] animals for which it would provide the same advantages. "At this point we just don't know who has them, besides us and macaques.”
Given that wrinkles confer an advantage with wet objects but apparently no disadvantage with dry ones, it's not clear why our fingers are not permanently wrinkled, says Smulders. But he has some ideas. “Our initial thoughts are that this could diminish the sensitivity in our fingertips or could increase the risk of damage through catching on objects."
Clearly this same article could have been published in a creationist journal with the expressed assumption that God is an amazing creator who made people with this God-given ability.
The war of worldviews continues.
