More than 90% of Human DNA Is Useless 'Junk,' Study Finds

This cuts against everything I&#x27;ve heard about genetics and epigenetic developments since the the complete of the HGP. It was my understanding that we were finding that the so-called &quot;junk&quot; DNA actually serves a variety of functions in regulating and controlling protein production and usage.<p>Wikipedia seems to agree: &quot;The Encyclopedia of DNA Elements (ENCODE) project[3] suggested in September 2012 that over 80% of DNA in the human genome &quot;serves some purpose, biochemically speaking&quot;.[4] This conclusion however is strongly criticized by other scientists,[5][6] with a recent article claiming that &quot;8.2% of the human genome is likely to be functional, while only 2.2% has maintained constraint in both human and mouse since these species diverged&quot;.[7]&quot;<p><a href="https://en.wikipedia.org/wiki/Noncoding_DNA" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Noncoding_DNA</a>

Over 90% of the human genome is able to mutate and still be viable. Much better than the reasoning I was expecting (We don&#x27;t know what it does therefore it is junk), but still seems like a bit of a stretch.
