If SIVagm was once a monkey killer, the change in its virulence may reveal the near future timing and span of the evolution of HIV. The new research also challenges the theory that one ancient SIV was transmitted vertically, down through time, and progressed into many SIVs as its initial web host diverged into many different species. Wertheim and Worobey suggest numerous SIVs arose because SIVs had been transmitted horizontally, between primate species, and progressed into a brand-new host-specific form just after transmitting. HIV arose from chimpanzee SIV that was transmitted to humans, most likely when people had contact with chimpanzee bloodstream from butchering and hunting the animals, Worobey stated.
