    Do Viruses Exchange Genes across Superkingdoms of Life?

    Viruses can be classified into archaeoviruses, bacterioviruses, and eukaryoviruses according to the taxonomy of the infected host. The host-constrained perception of viruses implies preference of genetic exchange between viruses and cellular organisms of their host superkingdoms and viral origins from host cells either via escape or reduction. However, viruses frequently establish non-lytic interactions with organisms and endogenize into the genomes of bacterial endosymbionts that reside in eukaryotic cells. Such interactions create opportunities for genetic exchange between viruses and organisms of non-host superkingdoms. Here, we take an atypical approach to revisit virus-cell interactions by first identifying protein fold structures in the proteomes of archaeoviruses, bacterioviruses, and eukaryoviruses and second by tracing their spread in the proteomes of superkingdoms Archaea, Bacteria, and Eukarya. The exercise quantified protein structural homologies between viruses and organisms of their host and non-host superkingdoms and revealed likely candidates for virus-to-cell and cell-to-virus gene transfers. Unexpected lifestyle-driven genetic affiliations between bacterioviruses and Eukarya and eukaryoviruses and Bacteria were also predicted in addition to a large cohort of protein folds that were universally shared by viral and cellular proteomes and virus-specific protein folds not detected in cellular proteomes. These protein folds provide unique insights into viral origins and evolution that are generally difficult to recover with traditional sequence alignment-dependent evolutionary analyses owing to the fast mutation rates of viral gene sequences.

    Do Viruses Exchange Genes across Superkingdoms of Life?

    Well, Mr. Bond, the abysmal depths of your ignorance is showing, as usual.

    So what of those who totally believe everything evolutionists say a absolute truth, because that's all they hear?

    Science ultimately can only regard what it observes now and not pretend to see what once happened. To classify the supernatural as "mythology" is akin to classifying science as "magic" and I cannot imagine you'd choose such a word to define what you respect.

    Pathogens are not mentioned in the Bible. You embarrass yourself to say so.

    And yes, tell us all again how you outsmarted all the scientists that taught the uneducated slob creationist blogger you plagiarize everything he ever knew about the material. Nope, nothing absurd about that at all...

    I don't have any problem with this fantasy. It doesn't get in the way of science or contradict science, unlike all of the garbage you usually vomit .

    Huh? You're rambling. I have no idea what you are talking about.

    >>Pathogens are not mentioned in the Bible.<<

    It's mentioned as how we can keep good health and prevent disease. It helps how to avoid germs.

    The topic was HGT. I'll ask the same question I asked the OP poster. What fascinates you about it?

    >>What do I find fascinating about HGT? That for most of history we didn't believe that this kind of genetic transfer was possible.

    How does it 'destroy Darwin'? Darwin postulated on 'the origin of the species' - that modern species all descend from earlier ancestor species. Darwin of course didn't know about genetics or genes when he came up with his theory.<

    HGT only in single cell. Not multicellular, so not that big a deal.

    Darwin claimed vertical transfer for his common ancestor theory.

    >>What has happened in the last 150 years is that our knowledge about evolution has expanded as our knowledge of biology has expanded. The science- including genetics- still show for example that modern whale species descended from earlier whale species which in turn came from earlier land species. H.G.T. doesn't change any of that- but it does show there are additional ways that genes can transfer- which is fascinating and will need to be incorporated into any genetic research of any species.<<

    We do not adequate evidence of macroevolution of whales and land animals.

    HGT doesn't have anything to do with it and you admit that. So, what's the big deal?

    Darwin was wrong about vertical transfer.

    ETA: Sometimes I miss your reply because your avatar is similar to others who do not use one. I go through my alerts and then try to go through the forum, but probably miss your reply when going through the forum.

    Oh really? Sterilization methods are mentioned? Contagions are mentioned, and how to avoid passing a cold? No....this is just more "snap to fit" religious bullshit.

    Sterilize is a more modern term. It didn't mean the same in ancient times; It meant castration. You mean sanitation and disinfection.

    "The one to be cleansed shall then wash his clothes and shave off all his hair and bathe in water and be clean Now afterward, he may enter the camp, but he shall stay outside his tent for seven days." Leviticus 14:8

    Castration is mentioned, too.
