Evolutionary biologist Dan Graur has published new calculations proving that a maximum of 25 percent of the human genome is functional. This counters the previous findings of ENCODE scientists.
University of Houston evolutionary biologist Dan Graur has published new calculations showing that a maximum of one-quarter of the human genome is functional. These findings contrast with the notion promulgated by Encyclopedia of DNA Elements (ENCODE) scientists that 80 percent or more of the sequence is functional. Graur’s work estimates that the human genome’s functional portion is more likely between 10 and 15 percent, with 25 percent representing the upper limit. The remainder of the genome is essentially “junk DNA”, harmless but also useless and not encoding for anything.
