Why would you think I know any less about evolutionary biology or biochemistry than astronomy?
I think it should only be apparent that I have some knowledge of the hard sciences in general, and perhaps you shouldn't make assumptions just because I haven't claimed to be a virologist specifically.
It might be a good idea to restrain your claims to those areas where you are less likely to be wrong.teo123 wrote: ↑Sat Mar 21, 2020 10:33 amMy area of expertise is onomastics, a part of linguistics, and compiler theory, a part of computer science, since I've written research papers about those things. And I am rather unlikely to get things very wrong about those things, or things closely related to that.
You were making the same mistake about viruses as you made about bombs. You misunderstood thermodynamics and believed bombs couldn't detonate. You misunderstood r-strategy evolutionary mechanics and assumed viruses couldn't replicate.
There's no reason to believe that, they may or may not all have a common ancestor. It's entirely possible that all life shares a common ancestor. There are plenty of cases of convergent evolution too.
There is probably some truth to the concept of "irreducible complexity" when it comes to viruses affecting modern cells. To exist today they would have needed to piggyback along with complex life on the evolutionary path, so their lineages probably trace back to the most primordial life -- life which no longer exists as far as we know. You almost certainly wouldn't have a capable virus spontaneously arrive from some broken RNA or DNA of a normal cell, such a change would require too many very convenient simultaneous mutations.
If you somehow eradicated all viruses today, they probably could not evolve again unless through bacterium (which is plausible, though unlikely as a origin).
Wikipedia briefly covers the theories here, and the problems with the cellular "escape" origin theory you're advancing:

No, no it doesn't suggest that. It only suggests that perhaps THAT segment of RNA came from us.teo123 wrote: ↑Sat Mar 21, 2020 10:33 am The fact that we have the genetic code similar to that of some RNA viruses inside our DNA strongly suggests the viruses (at least ones based on messenger RNA) came from us, or some specie that also has that code. I distinctly remember we were taught in school that there is no known mechanism by which code from RNA would be copied onto DNA.
You would have to compare the plausibility of such a case of transcription to the plausibility of a virus capable of infecting modern cells arising spontaneously, the latter being so absurd that I feel like you've reverted to your Flat-Earth claims here.
This suggests that there IS a mechanism, or it's just a coincidence which would still be more plausible. But as it stands there are in fact obvious mechanisms.
There are plenty of ways that code from human DNA could end up in viral RNA -- of EXTANT viruses. RNA polymerases produce RNA segments corresponding to single strands of DNA during certain processes, and there's no reason that viral RNA (again, of an EXTANT virus) could not accidentally incorporate segments like this in the process of its own infection and replication. That's how viruses exchange genetic information after all, by infecting the same host where the RNA can mix and match in a big soup. The host RNA just happens to be part of that soup too.
There are just too many simultaneous traits a virus would have to develop to arise de novo from random DNA or RNA with no viral ancestor. It's on the order of misunderstanding evolution as the crocoduck.
As I mentioned before it's plausible that bacterium could evolve into viruses by developing some kind of aggressive cellular infection based replication tactic, since they already have mechanisms to exchange DNA, and then losing all vestigial characteristics. It's not plausible that this would occur with a human cell.
No, it's not at all like that. That's also a system designed to be READ ONLY. Unknown does not equate to something that is known to be impossible.
I already explained an obvious mechanism by which that RNA could get into viruses without having *created* the virus. You're making all kinds of assumptions here.
Teo, READ IT. It explains the second law of thermodynamics which you misunderstood leading you to believe bombs are impossible.
Either read it or stop making claims that derive from that point of ignorance.
You mean the libertarian pundit who works for Fox news?
Libertarians and Republicans lie in a lot of the same beds, particularly when it comes to fiscal conservatism and rejection of progressive reform and welfare.
I was informing you about the source you referenced.
I think @Jebus covered this one.
Well that's an extraordinary claim for them to make, they're probably just parroting what they're told to report. You said it's the national media. Look at other Croatian sources, like independent journalists.
Aside from the fact that it falls below on rankings like the press freedom index, and has a high level of corruption?
Maybe do a Google search and read a few of the top result, if they aren't censored in your country:

Croatia is not a country known for freedom of speech. Yes, the constitution guarantees it, but that doesn't mean anything: so does China's.
You live in a country with a high corruption index and with an oppressive government.
The U.S. and Germany have their issues too, but it's easy to access news on broadcast very critical of the government and police and it's not illegal to do things like insult the police on twitter.
Your impression is biased by nationalistic delusion. Croatia objectively does not have more free speech.
That is one cherry picked example that sets it apart from Germany, but there are far more ways in which it is worse. Also, that's more an indication that Croatians are ignorant than that they have free speech.
That's a ridiculous lie. The U.S. is rife with Nazis denying the holocaust in the alt-right. No, it's not illegal there.
Your incompetence and unwillingness to do even the most basic fact checking is outright offensive. How can you be so profoundly stupid and arrogantly assertive of these claims at the same time?
That's such an idiotic claim I don't even know how to reply to it. Political correctness is not a challenge to free speech, there are no LAWS on political correctness, it's really only a question of whether your advertisers will drop you for being too rude. Meanwhile Croatia will fine and lock up journalists. Go back to believing Flat-Earth Teo, that was more sensible.teo123 wrote: ↑Sat Mar 21, 2020 10:33 amThe media in Croatia rarely mention political correctness, and, when they do that, they do that to mock the political movements in other countries. Political correctness is the biggest obstacle to free speech in the western world, and Croatia appears to be mostly free of that.
You're not going to waste my time with bullshit like this. Just shut up. Shut up about virology, shut up about your ridiculous nationalistic delusion on how free you think your fatherland is, shut up about whatever brainwashed alt-right neocon garbage you're getting into now. I get that you want to be edgy and have opinions other people don't get, but yet again you're wrong about damn near everything you say. It's like an art to be able to be wrong so frequently, you do worse than chance and that's amazing.
