Genetically we are 99.9% chimp.![]()
Close, but not quite that high ![]()
“It is widely held that ‘The common chimpanzee (Pan troglodytes) is our closest relative. Its genome sequence is about 98.8% identical to our own, and we shared a common ancestor some six million years ago.’1 In a recent article,7 David A. DeWitt cited a study which found that the two species are only 95% identical when insertions and deletions are considered,8 showing that the estimate of divergence depends mainly on what type of DNA is being compared.”
