A myth repeated so often in museums, textbooks, and nature documentaries that most people accept it as dogma is that humans and chimpanzees share 98% to 99% of our DNA. The Smithsonian Museum of Natural History in Washington, D.C., for example, cites this statistic in its Human Origins exhibit as confirmation that “modern humans and chimpanzees diverged from a common ancestor between 8 and 6 million years ago.”
The only problem is the statistic is wrong, likely by an order of magnitude. Even more, the science community has known that it is wrong for a while now, and new methods of comparing the genomes of humans and great apes show just how genetically different the two are. In fact, the cited 1% to 2% difference hasn’t really been defensible in years.
As far back as 2007, authors in the journal Science called on fellow researchers to retire “the myth of 1%.” Geologist Casey Luskin explained, in a 2023 ID the Future podcast, that the estimate was derived decades ago from a single protein-to-protein comparison before the chimp genome was even fully sequenced. Since then, genetic science has become far more precise, and almost no modern comparisons between human and chimp genomes yield the famous 98% to 99% statistic.
