"Behold, I will do a new thing, Now it shall spring forth; Shall you not know it? I will even make a road in the wilderness And rivers in the desert." (Isaiah 43:19, NKJV)

Almost every living organism has tiny stretches of DNA that repeat over and over again. Scientists call these tandem repeats, and for a long time they were mostly ignored and even called ‘junk DNA.’ But it turns out these repeats can actually affect how genomes work, how traits appear, and how different organisms are unique from one another.
