Final answer:
The rhesus monkey and gibbon are primates, but not as closely related to humans as chimpanzees and bonobos.
Step-by-step explanation:
Both the rhesus monkey and the gibbon are primates, which means they belong to the same order as humans. However, they are not as closely related to humans as chimpanzees and bonobos. Genetic evidence shows that chimpanzees and bonobos share a more recent common ancestor with humans.
