Scientists compared the DNA of humans with the DNA of four other primate species. The table shows the results. Table
| Species | Chimpanzee | Gorilla | Orangutan | Macaque |
|---|---|---|---|---|
| Percentage of DNA the same as human DNA | 98.8 | 98.4 | 96.9 | 93.0 |
| Which conclusion is best supported by the data? |
Humans evolved from chimpanzees, which are still alive today.
Gorillas are more closely related to humans than orangutans are.
Macaques are not related to humans because their DNA is different.
Orangutans evolved more recently than gorillas or chimpanzees.
