Agreed. There's something about the gestational phase, aka nanotechnological self-assembly, that surely requires at least a few lines of code(!) and which otherwise is never used again -- until passed on to the next generation. Probably a good bet that the "repetitive elements" are accumulated lines of code for all successive phases of fetal development, from single-celled organism to two, to four, etc until all echoes of evolution are replayed and the present species emerges. "Junk," indeed.
