Quizplus · Accepted Answer

HIV-1 is believed to have been transmitted to humans from chimpanzees, specifically the subspecies Pan troglodytes troglodytes. This transmission likely occurred through the hunting and consumption of infected bushmeat by humans. Gorillas and sooty mangabeys can also carry simian immunodeficiency virus (SIV), but they are not believed to be the source of HIV-1. African green monkeys and baboons can carry different strains of SIV, but they are not known to have transmitted HIV-1 to humans.
