HIV is a virus!

Viruses are not sloppy replicators.

Well I earned my degrees in the 21st Century and just like the OP stated it was a term used long ago and far away. I've never seen or heard that term until I found the "Understand Evolution" website.

As the OP stated: A life scientist makes no such distinction, evolution is evolution, regardless of the size of the organism.

You being a retired geezer has nothing to do with it. I've never heard this term used and in fact I've never seen it used in the University or work setting. You will never find a trained scientist using that term when discussing Evolution.

Yes, I know.

HIV is.

When drugs against HIV do not work, it is often because the virus has become resistant to one of the drugs being used. This resistance is the result of mutations that occur in the viral genes.

Unfortunately, use of anti-HIV drugs can actually promote the reproduction of resistant virus particles. Untreated, HIV makes approximately 10 billion new virus particles every day in an infected person. But HIV does not copy its genetic material very accurately. Because of its sloppy replication, each one of these new virus particles may be different from the parent virus in one or more genes.

I have already pointed out that this is not a very scientific way of explaining things. Your link is intended for folks in grades 9-12.

Most in the US are not scientifically literate therefore using links intended for 9-12th graders might be appropriate even in the science forum. *shrug*

You can call it sloppy but it's commonly referred to as replication errors.

Mutations in HIV-1 Reverse Transcriptase Affect the Errors Made in a Single Cycle of Viral Replication

Quote:
Errors made during HIV replication underlie the development of drug resistance and the ability of the virus to develop mutations that allow it escape from the host's immune system. Thus, it is important to understand the contribution that RT makes to the errors made during HIV replication and to understand how mutations in RT affect the errors that arise during HIV replication.

Viruses are constantly evolving, but so are we. And more importantly our immune systems are "evolving" every day.

One might worry that viruses and bacteria evolve so much faster than animals, that they could wipe us out any day. The thing is, they haven't obliterated us throughout the entire evolution of the animal kingdom.
