Question

Quizplus · Accepted Answer

The theory currently widely accepted is that the initial transmission of HIV to humans occurred through the hunting or handling of infected primate meat, leading to a spillover of the virus into the human population. This is known as the "bushmeat" hypothesis. The virus likely came from chimpanzees in West/Central Africa, but it cannot be said that all HIV variants in humans were derived from them.
