Nature is full of information and, while these viruses and cells don’t think, something in them does.

Viruses called phages, researchers say, are in a grey zone between life and non-life
Researcher: “Typically, what separates life from non-life is to have ribosomes and the ability to do translation; that is one of the major defining features that separate viruses and bacteria, non-life and life,” Sachdeva said. “Some large phages have a lot of this translational machinery, so they are blurring the line a bit.”
Something else to worry about?: Viruses stealing our genes
A new study promises to unveil “a novel mechanism that allows viruses to produce unexpected proteins.
At BBC: In case you wondered, what if all viruses disappeared?
We really do not know anything like what we should know about viruses before we just shut down our economies in a panic and so forth.
Another stab at Are Viruses Alive?
Hugh Harris: “Some properties of living things are absent from viruses, such as cellular structure, metabolism (the chemical reactions that take place in cells) and homeostasis (keeping a stable internal environment).” And yet, as he goes on to say…
Vague words in science: Vague or plague?
The worst part of witch hunts in science is that they so often involve controversies over words without precise definitions,
Is COVID-19 alive?
Villarreal and Mazur introduce a term that will be new to many— and relevant to viruses like COVID-19: quasispecies
Might COVID-19 be a recombinant of two pre-existing viruses?
Presumably, viruses don’t need to follow rules of heredity.
COVID-19 pandemic and zoonotic diseases (via animals)
The bad news, as you will learn, among other things, when you read the non-panic news, is that precisely because COVID-19 is much less lethal than SARS, it is apt to be around longer.
Michael Behe muses on design and COVID-19
Behe: … most viruses do not affect humans and may well have a positive, necessary role to play in nature of which we are currently unaware. (I would bet on it.) From time to time a storm arises in the virosphere and affects humans. But that’s no reason to think either that viruses weren’t designed or that the designer of viruses isn’t good.
Here’s a question that new ambigram viruses raise
“Not a random boo-boo on evolution’s part”? If the field of biology had not organized itself around Darwinian evolution (insert preferred terminology for the same sort of thing here) in the mid-twentieth century, would anyone think that up just now to account for all this?
What? A virus with no recognizable genes?
From what they’re saying, viruses don’t necessarily share any characteristics of common descent. Let alone universal common descent. Jury’s still out but this is big.
Large and giant virus proteins not linked to any known virus lineage
So giant viruses often boost host metabolism instead of destroying it and “the team was still unable to link 20,000 major capsid proteins of large and giant viruses to any known virus lineage”? Creation ex nihilo? Hey, don’t laugh.. Look, these days, they can’t even get mouse or human sperm to buy into Darwinism. Why would giant viruses care?
Even viruses have complex origins now
Well, this is interesting, for sure: “The findings show that this broad class of single-stranded DNA viruses, which infect all three cellular domains of life, have acquired their genetic components through complex evolutionary processes not traceable to a single ancestral event.” Maybe there wasn’t a “single ancestral event” for cells either. Also: The hope is to “resolve the question of how cell-based life came to co-exist with the planet’s staggering array of viruses (dubbed the virome).” One commonly heard hypothesis is that viruses are degraded cells. It will be interesting to hear alternative theses.
Do viruses play a hidden role in evolution?
Viruses seem to be everywhere, doing a lot of things, with apparent “ingenuity.” Maybe a discovery down the road will be that they cause many changes currently interpreted according to some Darwinian theory (kin selection, costly fitness, what have you … )
