[math-fun] junk dna

http://www.nytimes.com/2015/03/08/magazine/is-most-of-our-dna-garbage.html?_... the NY Times article is enjoyable but fails to mention that closely related species can differ in DNA by large factors. Which is very convincing evidence a lot of the larger one's DNA, must be junk. I'm not saying everything currently thought to be junk necessarily is -- the NYT article mentions the highly interesting "hotair" counterexample -- but there can be no doubt that well over 50% of some organisms' DNA is junk. One researcher quoted in the NYT piece says the old estimate 99% of the human genome is junk, is in his view now really 92%.
