    The theory behind this is decades old. Evidence in support of it is fairly new. One of the early explanations for why we have so much "junk" DNA is that its part of the material needed for faster, better evolution. However its also fair to say that as we learn more and more of the genome, less and less of it is "junk". Much was simply stuff we did not understand back then.

    I would not take this as proven yet, but definitely interesting.

    PS The thing about these stretches of DNA is they are often genes from other species, including viruses, as well as duplicated genetic mistakes. So they largely could code for various molecules, and only need a few genetic tweaks to become functional. However since they were "offline" so to speak, they could mutate without killing their carriers. If the mutation was lethal and they came online, that person would likely die long before birth.
