Reply to comment by seminote in TIL DNA transfer does not only occur "vertically", that is, from parent to progeny. There is also a form of DNA transfer known as horizontal or intracellular DNA transfer, which consists in a piece of DNA being transferred from the genome of one cell to that of another—including between species. by DioriteLover

Is it actually “junk” or possibly something we can’t detect it’s use due to lack of technology?

It’s junk. Nonsense codons. They don’t code for anything and are just artifacts of specific types of viruses that integrate into our genome. They actually are a great history book that scientists use to mark time points in human evolution.
