Comparisons of DNA base sequences among different viruses have provided the strongest evidence for the origin of HIV from non-human primates. Specifically, HIV-1 is closely related to a simian immunodeficiency virus (SIV) found in chimpanzees, and HIV-2 is closely related to an SIV found in sooty mangabeys. This suggests that the virus was transmitted from these animals to humans through contact with infected blood or other bodily fluids. Other forms of evidence, such as historical studies and medical histories, are not as strong or direct in supporting this theory.
