No, "junk DNA" was thought useless until recently.

Again Nineveh you are misinformed. This is the laypersons understanding. Genticists and paleobiologists realize that any DNA was usefull at one point and may become usefull in the future. When analysing the current influence of any DNA on enzyme production some effects are more apparent than others. The current effect of much DNA is still not known. Bob's one example does not change the whole of scientific understanding.
But of course your black or white thinking kicks in again. If there is one inaccuracy, it must all be wrong.
How sad.
Um... how does this make the assesment that DNA now is "junk"? OOPs no, sorry, they don't think it's "junk" anymore because it has a use now. They finally realized it wasn't just evo left overs but actually has a function. They labled it "junk" before they had a clue what it was or what it did.
To set the record straight:
Junk DNA Definition: Stretches of DNA that do not code for genes; most of the genome consists of so-called junk DNA which may have regulatory and other functions. Also called non-coding DNA.
"Junk" is somewhat a misnomer, because molecular biology remains a young science. Segments of DNA may function in additional ways that have not yet been discovered, which might suggest uses for much or all of the junk. Scientists generally keep this likelihood in mind even as they persist in using the word "junk," which for better or worse has stuck."

I would really like to read up on "may become useful in the future". Got a link?
