One of the most common arguments you will hear that Darwinian evolution must be true is the “Junk DNA” argument. It goes like this:
There are significant stretches of the human genome that appear not to code for any biological function. This is what you would expect if millions of years of random genetic mutations occurred in the genome. This junk DNA is simply left over from evolutionary history and is serving no purpose any more.
The argument makes sense, but there is only one small problem. Every year that goes by scientists are discovering more and more functions for this junk DNA. It turns out that it’s not junk after all. If the junk DNA is coding for biological function, then this particular evidence for Darwinian evolution falls by the wayside. Not only that, but this becomes positive evidence for the Intelligent Design community, as they have been predicting this very finding.
Take a look at this video where ID scientists discuss Francis Collins’ use of the “Junk DNA” argument in his book The Language of God.
