Genetic Blueprints. To map the chimp genome, researchers used DNA from the blood of a male common chimpanzee (Pan troglodytes) named Clint, who lived at the Yerkes National Primate Research Center in Atlanta. Clint died last year from heart failure at the relatively young age of 24. A comparison of Clint's genetic blueprints with that of the human genome shows that our closest living relatives share 96 percent of our DNA.
Further experiments by the same team showed that 98.5 percent of DNA sequences are shared by humans and chimps. The same methods showed that two humans share 99.9 percent of their DNA. In contrast, the DNA of humans and mice is only around 60 percent similar.
