Not exactly. You think that I'm a dummy, which is just one more of your foolish delusions. Put forward enough counter-factual opinions and people get to realise that your opinions are worthless. You won't, but your quality control criterion is whether an opinion agrees with yours, as opposed to objectively established facts.

not do any more damage to the cell than would otherwise happen and the two viruses have little impact on one another other than competing for the same machinery. So it is very easy for two virus types to share NA

The cell's replication machinery is making at least two independent virus components - the protein shell and the genetic material. In some viruses the genetic material is split into two or more separate components.



If we are talking about different strains of a flu virus, the protein shell will be more or less the same, but it's unlikely to exactly suit the genetic material from the other strain.

Correct. Which is why James Arthur's "hyper-accelerated artificially-directed human-targeted viral evolution" is such a load of alarmist rubbish.



BTW, given that each time a person is infected it is like inoculating a petri dish, the natural process can result in some very fast mutations. There are a lot of petri dishes out there. In the lab not so many.



In the lab the viruses that get to survive, replicate and mutate can be selected - to some extent. In wild the capacity to replicate and get dispersed is the only criterion.

In the wild a lethal flu virus is at a mild disadvantage - its hosts die and stop getting around to infect other people before their immune systems have stopped cells getting infected and churning out copies. It's a mild disadvantage because most of the propagation is done in the early stages of the infection.

Interestingly about 8% of the human genome is provirus, which is A LOT. That is virus DNA integrated into nuclear DNA and frozen there, no further replication. And this stuff is heritable, passed down to subsequent generations.

Ummm, no. There is a cell destruction known as apoptosis. I suppose it could be called a suicide because the cell thoroughly deconstructs itself to the point of shredding it own nuclear DNA.

Bloggs, what is your point? I was showing that your statement,

"Multiple viruses hitting the cell all at once are all going to be

trying to take over the cells replicating machinery at the same time.

The likeliest outcome is a very dead cell and no new viruses. " is not

valid. Do you have a response to that?

My response is I never made that statement. Multiple virus infection of a single cell is called superinfection and has been observed for nearly 70 years now. The outcome depends on the viruses and the host cell.

You actually don't know anything about this and are making all this up,

Wrong.

Look up r-selection for species and learn about reproduction
techniques. The effect you are talking about is not very significant.

Everybody knows about reproductive strategies. It would be a very unusual virus which could opt for any strategy except maximising the number of of it's off-spring. Viruses aren't really equipped to modify the environment their off-spring are exposed to.
This process only has to produce one new virus that ultimately infects
another cell and begins multiplying.

It's got to produce a lot more than one to have any significant chance of producing an off-spring that can get to cell it can infect.

> We aren't talking about the mainstream method of propagation for the new virus, just how one can be created.

But the chance of the new virus getting a chance to propagate also gets into the calculation.
Producing one that was as viable as the flu virus would be an even longer stretch.

And that is what evolution is all about. It can take millions and even billions of rolls of the dice to get a combination that is an improvement, but the viruses have lots of time and replicate very, very quickly in huge numbers.

The human population had also been selected by the process. Apparently there's a human gene variant that provides protection against AIDS which is more common in people whose ancestors survived close encounters with the bubonic plague (as in relatives dying of it).

The first outbreak of the plague killed off about 30% of the population.All three of the Limburg Brothers - famous medieval artists who came from Nijmegen (which is how I got to hear about them) all died in the same outbreak. That family clearly got selected out.

It wasn't his statement, but mine. And my response is that since your counter-argument consists of a statement that one the less likely outcomes - some mixed up viruses - is still likely enough to be significant, you can scarcely use that as a basis for claiming that the part of my statement that you have quoted isn't valid.

I did go on to observe that a mixed virus was one of the less likely potential outcomes, so what we are in fact arguing about is the numerical weight you should attach to "likely" and "less likely".

And my response is that since your counter-argument consists of a statement that one the less likely outcomes - some mixed up viruses - is still likely enough to be significant, you can scarcely use that as a basis for claiming that the part of my statement that you have quoted isn't valid.

I did go on to observe that a mixed virus was one of the less likely potential outcomes, so what we are in fact arguing about is the numerical weight you should attach to "likely" and "less likely".

Who are you, George Bush Sr? "no new viruses" BUSTED!

Since I failed to say "no new viruses" and in fact explicitly observed that they did get produced - if not very often - it's your stance that is busted, rather than mine.

Are you intentionally channeling James Arthur's pathetic strawman style of argument, in which case you earn satirist points, or are you just demonstrating that you can't process a statement that stretches over more than one sentence?

This process only has to produce one new virus that ultimately infects

another cell and begins multiplying. We aren't talking about the

mainstream method of propagation for the new virus, just how one can be

created.

No such merging of /unrelated/ viruses has been observed.

"Many viruses (for example, influenza A virus) can "shuffle" their genes with other viruses when two similar strains infect the same cell. This phenomenon is called genetic shift, and is often the cause of new and more virulent strains appearing. Other viruses change more slowly as mutations in their genes gradually accumulate over time, a process known as genetic drift."

Since there is and always has been unlimited opportunity for something like this to occur, it cannot happen between unrelated strains.
