HIV in 1920s Kinshasa, but AIDS was observed in the 1980s…

…[a team of international scientists used] archived samples of HIV’s genetic code to trace its source, with evidence pointing to 1920s Kinshasa [what is now the Democratic Republic of Congo].

Give the rapid mutation of ‘HIV’, how can you be sure that Kinshasa was the source rather than a point of mutation? (Assuming HIV is a virus)

…Their report says a roaring sex trade, rapid population growth and unsterilised needles used in health clinics probably [emphasis added] spread the virus.

So, why did not Kinshasa experience a population wipe-out long before AIDS was defined and connected to ‘HIV’?

…HIV is a mutated version of a chimpanzee virus, known as simian immunodeficiency virus, which probably [emphasis added] made the species-jump through contact with infected blood while handling bush meat. 

2 probablys in this article emphasises that this study leans more on conjecture than fact.

…Dr Andrew Freedman, a reader in infectious diseases at Cardiff University, said: “It does seem an interesting study demonstrating very elegantly how HIV spread in the Congo region long before the Aids epidemic was recognised in the early 80s.

If we observed AIDS only in the 80s with no historical record of AIDS in Kinshasa (though, given the broad definition of AIDS there must have been qualifying illnesses) there is an obvious disconnect between HIV and AIDS.
