Sir, How the HIV came to human body from a green research monkey? &&&
How HIV was found in a green research monkey as the virus is a human virus?

Question

In 1999, a strain of SIV (called SIVcpz) was found in a chimpanzee that was almost identical to HIV in humans.

The researchers who discovered this connection concluded that it proved chimpanzees were the source of HIV-1, and that the virus had at some point crossed species from chimps to humans.3

The same scientists then conducted more research into how SIV could have developed in the chimps. They discovered that the chimps had hunted and eaten 2 smaller species of monkeys (red-capped mangabeys and greater spot-nosed monkeys) and became infected with 2 different strains of SIV.

The two different SIV strains then joined together to form a third virus (SIVcpz) that could be passed on to other chimps. This is the strain that can also infect humans.
