Junk DNA: How useful it is

Did you know that most of the DNA (98.5%) in your body is useless junk? Well, not really, but evolutionists used to believe this theory was a scientific fact, and they’re just now beginning to realize they were wrong.

The term ‘junk DNA’ was first used by geneticist Susumu Ohno in 1972. Back then, only 2% of DNA had any known function, so it was believed that the remainder had no biological function and was, therefore, useless garbage left over from our evolutionary past. Others described this genetic material as a “grab-bag of broken genes and virus-like sequences called mobile elements that hijack the cell’s DNA copying-machinery from time to time and insert new copies of themselves back into the genome.” Evolutionists have referred to junk DNA as “astonishingly selfish,” and have predicted that “people will use genetic engineering to strip junk DNA from their genomes.”

Over at Discover Magazine, however, there’s an article informing its readers that junk DNA may not be as useless as they once thought- and might actually play an important role! This is fascinating because we’ve known about the importance of this non-coding region of the DNA for some time now- at least since the Human Genome Project’s ENCODE began in 2003. I was writing articles about the usefulness of junk DNA in 2012. So why has it taken evolutionists so long to catch on?

I think part of the reason is because it was a failed evolutionary prediction, and predictions play an important role in science. A successful prediction is evidence validating a given theory, while a failed prediction is evidence falsifying that theory. And what evolutionist would concede that evolution is wrong? Not many.

Yet, since the ENCODE project began, we’ve learned that about 80 percent of the genome is functional, and, according to Lead Analysis Coordinator Ewan Birney, he predicts that it’s likely to increase to 100 percent. Some important functions include gene regulation during development, enhancers for transcription, silencers for suppression, and regulating the translation of proteins. The DNA is there to control how cells behave, and they can be used to diagnose and treat diseases such as cancer.

It never did make much sense to think there would be useless junk in our DNA. Why? Because organisms don’t spend biological energy needlessly. In fact, this is one reason why evolution is demonstrably wrong. For example, blind cave fish have no eyes because it would be wasteful to support a function the organism has no need for; it would be better to spend the energy elsewhere. Therefore, if part of the genome is useless, it is discarded at the genetic level. But the fact that ‘junk DNA’ exists is evidence that it’s not useless. Yet it seems that evolution requires useless, evolutionary leftovers to justify it as a theory. On the other hand, Intelligent Design advocates predicted this material would have function.

One part of the article I really loved is when the author explains, “If protein-coding sequences are the notes of a symphony, then some of the non-coding sequences act like the conductor, influencing the pace and repetitions of the masterpiece.” This is an absolutely amazing admission from an evolutionist! As a creationist, I love that evolutionists can see complex design and compare this process to a symphonic masterpiece complete with a conductor- and I would suggest that the conductor and creator of this masterpiece is God.
