I have a request that I hope some readers can help me with. I am looking for examples from the literature (rather than any “general sense”) of people who claimed that “junk DNA” or “selfish DNA” was totally non-functional. I am particularly interested in peer-reviewed primary articles, but media reports and textbooks are of interest too. Anything from the 1970s to the present would be useful, especially pre-2000 publications. I suspect that the assumption that junk = totally functionless arose sometime in the 1990s, and hardly qualifies as a long-held view. I would also be interested to see references in which people suggest that the term “junk” was meant only to reflect our ignorance about what non-coding DNA is doing in the genome. Post your examples (with a quote and full reference info) in the comments. (Please don’t list Ohno 1972).
