DNA does not, as we thought, carry a linear, one-dimensional, one-way, sequential code—like the lines of letters and words on this page. And the 97% in humans that does not carry protein-coding genes is not, as many people thought, fossilized ‘junk’ left over from our evolutionary ancestors. DNA information is overlapping-multi-layered and multi-dimensional; it reads both backwards and forwards; and the ‘junk’ is far more functional than the protein code, so there is no fossilized history of evolution.
