This seems like flawed argument to me (the argument put forward in that article). Just because different species contain the exact same sequences doesnt mean it is important, it could just as easily mean it is completely unimportant, and as such not affected by the laws of natural selection. If the genetic sequence in junk sections of dna is never selected for (because it does nothing) then it will never change.
I was under the impression that was why these 'junk' segments are the same in most species. But, i was never very interested in genetics, so i never looked much into it. Therfore, i may be completely wrong.
What i do remeber is these segments are left out when coding for proteins, and since that is all dna does...if these segments dont code for proteins they do nothing?
