How do we know that HIV evolved from Simian Immunodeficiency Viruses (SIV) that
"jumped" from chimpanzee and monkey species to humans?
All of the above.
Because butchered meat of chimpanzees and monkeys may have been a vector
to our species.
Because HIV clades are nested within clades of SIV.
By reconstructing phylogenetic trees for strains of HIV and SIV.
