I Accept the Theory of Evolution

Humans and chimpanzees both carry inactive genes acquired from viruses.
This occurs because some viruses insert a copy of their genome into the DNA of whichever species they infect. These are called retro-viruses... HIV is one such.

Where such viruses infect the cells that produce sperm and eggs, they can be passed on across generations.

The human genome contains thousands of these remnants of long-past infections... now rendered harmless... and so does the chimpanzee genome.

Most of them are in exactly the same place on both genomes.
That’s astonishing, so I’ll repeat it: most of them are on [i]exactly[/i] the same place on both genomes.

Let’s choose an explanation from a few (non-exhaustive) options:

1. astonishing coincidence

2. when the gods created humans they decided to sprinkle around several thousand retro-viruses, and they put the preponderance of retroviruses at matching sites on both species because... umm... because... well... because... stop questioning the gods!

3. The majority of retroviruses match because both species inherited them from a common ancestor, who had itself accumulated them from the line of its own descent.

The small number which do not match are the remnants of infections that each species has warded off independently since divergence from the common ancestor... as predicted by the Theory of Evolution.

Interesting. Do you believe aides came from monkeys?

@Mk8155 The HIV-1 strain (the virulent, easily transmitted strain that we see worldwide) has been traced to chimpanzees, where it's known as the simian immunodeficiency virus (SIV).

The much rarer, and less transmittable, HIV-2 strain seems to be associated with Old World monkeys in West Africa.

So, as far as we humans are concerned, the source is chimpanzees rather the monkeys i.e. it's primate to primate.
@newjaninev2 I thought one theory is that the virus crossed from chimps to humans around 100 years ago when a hunter ate an infected chimp. It was brought from Africa to the West by a French airline steward.
