Read the whole thing, Wright was wrong!! And he knew it or he is uneducated and uninformed and ignorant!!
"HIV, which is thought to have first emerged in humans in the 1930s, is
another kind of virus, known as a retrovirus. These simple viruses are
akin to elements found in normal cells that have the ability to copy
and insert themselves throughout the genome. There are a number of
viruses that have a similar way of copying themselves—a process that
reverses the normal flow of information in cells, which is where the
term "retro" comes from—and their central machinery for replication may
be a bridge from the
original life-forms on this planet
to what we know as life today. In fact, we carry among our genes many
"fossilized" retroviruses—left over from the infection of distant
ancestors—which can help us trace our evolution as a species."
