>most evolved

What do you mean by this? Humans are actually very unevolved. Other species like Polychaos dubium, an amoeboid, has a genome that has in its DNA, 670 billion base pairs, 200 times larger than the human genome. How and why you ask? Because it has evolved a great deal more than humans have. All that extra DNA isn't even used, but some may be used when the right environment trigger occurs. I'd say that Polychaos dubium is far more evolved than humans will ever be. Though some of those numbers may be in dispute, there are 1000s of other species that have a great many more base pairs than humans.

Prions. Viruses are well known and can also easily be killed a lot easier than your regular mammalian cell with higher temperatures or extremes in pH.

>why are you making multiple threads about the same thing?

What do you mean? I havent made a single thread on /sci/ in years and I'm just replying to posts.

>>7750309

Bad analogy. Prions are organic molecules. Automated machines are also made by other entities. Prions are a random occurence unless they were made in some lab somewhere.

>> No.7750372

prions are viruses though, just with different structure

viruses are made of proteins too, but they are just assembled differently

prions are extremely advanced viruses, unlike anything else, really

No, they aren't.
They're nothing like viruses. A virus is a load of proteins all bundled up in a shell.
A prion is just a single misfolded protein.

I have trouble drawing the line of "life" below the virus. I define life as using DNA (software) and proteins (hardware) in a metabolic pursuit. Viruses have the first two items, but don't metabolize. I pretty much agree with the other poster who simply characterized them as a parasitic structure.

yes they are.
there is no such fucking thing as proteins which infect other proteins,
that is beyond fucking retarded, holy fucking shit. you got to be kidding me. its literally the dumbest thing they could possibly come up with as an explanation for shit they cant figure out.

somewhere along the line a virus involved, or it might even be a more advanced organism. whatever it is, it's completely unknown, and the more investigative work that is done, the more it just scares the fucking shit out of science.

It does not actually reproduce itself. It uses single celled organisms which are capable of doing that to perform that function.

It is basically the biological equivalent of a chain email or pyramid scheme. It's just information structured in a way that compels the host organism to spread it.
