HIV's complex family history unravelled
19:00 12 June 03
NewScientist.com news service
The parent of the HIV virus was the product of a union between two monkey viruses, genetic detective work has revealed.
This genetic mixing occurred in a chimpanzee at least one million years ago, although it is thought that HIV did not cross into humans until the 1930s. But the discovery has prompted researchers to speculate that chimps may still harbour other HIV-like viruses that could jump to humans.
The complex genetic history of HIV viruses came to light when researchers tried to construct family trees connecting the different genomic elements in the viruses. If the viruses shared the same genetic history, you would expect these trees to match up, but they did not.

I don't buy it. Didn't they say at first, that it came from humans having sex with monkeys?

Byrd,
as a man who critiques the scientific standards of others on this board, surely you understand that this article is too short and vague..
In one or two sentences, the authors talk about gene splicing through ingestion (!?)... now, doesn't that seem rushed to a man of science like yourself???
Yes, Newscientist is a cool sciencemag, but this article is far from explaining the origing of HIV. If I've misread the under-tones of this article, please correct me

My uneducated guess is that being more liberal and having multiple partners, before extensive safe sex publicity, created a more observablr rapid spread. But I don't think it would be sensible to apply a wrath of God hypothesis to that.
If you travelled through Africa today, where in some countries 30%+ of the population is HIV+, you would dispense with your notion that it is in some way a gay disease.
