The Myth of Junk DNA

DNA has been referred to as the “molecule of life.” It’s an extremely complex molecule, behaving like a chemical code, instructing cells how to grow, develop, function and self-repair. But once upon a time evolutionary scientists found non-protein coding regions of the DNA and concluded that 99% of our DNA is useless junk- leftovers from our evolutionary past and without function. But that was a huge mistake.

The Discovery Institute has created some clever short videos supporting intelligent design, and this one delves into the myth of junk DNA and how it inhibited scientific progress.

According to evolutionary scientists, evolution predicts that our DNA should be full of junk, and they argued it was “folly” to search for function. They argued that over half our genome was parasitic, using large amounts of space, and more than 95 percent shouldn’t be there at all!

Many evolutionists like to claim that science proves evolution, but from this example we learn that science does no such thing. Science doesn’t say anything about evolution. It’s people who make these claims in the name of science, hoping to sway opinion and sound authoritative.

Fortunately for science, advocates of intelligent design (ID), like William Demski, resisted the consensus, predicting that scientists would find function in these regions and warned that the term “junk DNA” discourages scientific inquiry.

Today we know there is purpose and great functionality in this non-coding region, and much of it has to do with regulation and gene expression. Just as blueprints are necessary to build a house, so this DNA is necessary for building cells and body parts by determining when to stop and start building. Ingenious!

But how did ID scientists get it right, and why did evolutionary scientists get it wrong? It has to do with our presuppositions and worldview. The ID worldview presupposes that our DNA was created by God with purpose, meaning and function. God didn’t insert junk into our DNA, but created a complex, useful computer code to build our bodies starting at the time of conception.

Evolution, on the other hand, denies God’s existence, so there is no goal in mind; therefore, evolution must experiment through trial and error until it gets something right and can pass that information along to the organism’s offspring. So evolutionists start with a wrong premise, and that’s why junk DNA is a prime example of a failed evolutionary prediction and is strong evidence against evolution.
