This is from Nature news. I knew that an AIDS-like disease has been described way before the term AIDS was GRID. For sure the HIV has been around for a while.
Using a database of HIV-1 sequences and an estimate of the rate at which these sequences change over time, the researchers modelled when HIV-1 first surfaced. Their results showed that the most likely date for HIV's emergence was about 1908, when Léopoldville was emerging as a centre for trade.
