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.
This family includes orangutans, chimpanzees, gorillas, and bonobos. Of the great apes, humans share 98.8 percent of their DNA with bonobos and chimpanzees. Humans and gorillas share 98.4 percent of their DNA. Once the apes are not native to Africa however, the differences in DNA increase.
