It MIGHT have been possible but Occam's Razor says it's more plausible it evolved naturally and just jumped species.
FAR FAR FAR more plausible.
China has had multiple SARS escape accidents.
E.g. "killer bees" are a product of human scientists trying to engineer a better bee - the release was accidental. It's not like we have the ability to genetically engineer a bee from the ground up. But as a species humans have been purposefully manipulating the traits of living things for thousands of years.
More likely than building the virus is studying it and accelerating it’s development.
Now I’m not saying that’s what happened here however without the cooperation of the CCP we’ll have no idea what the truth of the matter is

It turns out we've been doing "serial passage" research for some time, which is where we leverage natural selection to do our genetic engineering for us, rather than manually editing genes. This is how we engineer viruses to jump species - on purpose.
> They did it using serial passaging: repeatedly dosing a mixed solution of mouse cells and hamster cells with mouse-hepatitis virus, while each time decreasing the number of mouse cells and upping the concentration of hamster cells. At first, predictably, the mouse-hepatitis virus couldn’t do much with the hamster cells, which were left almost free of infection, floating in their world of fetal-calf serum. But by the end of the experiment, after dozens of passages through cell cultures, the virus had mutated: It had mastered the trick of parasitizing an unfamiliar rodent.
In fact, "we" (meaning humanity) have even been experimenting with serial passage into humans.
> A few years later, in a further round of “interspecies transfer” experimentation, Baric’s scientists introduced their mouse coronavirus into flasks that held a suspension of African-green-monkey cells, human cells, and pig-testicle cells. Then, in 2002, they announced something even more impressive: They’d found a way to create a full-length infectious clone of the entire mouse-hepatitis genome. Their “infectious construct” replicated itself just like the real thing, they wrote.
The whole article is really worth a read.
The general evidence is this is yet another reason why wet markets are terrible for humanity, not that it was made in a lab and got away. But you can build lots of things.
A random virus, no. This one, we do.
We can't build a virus from scratch. But we can combine pieces of different viruses to build a new one. The same thing also happens naturally when an animal is sick with 2 viruses at once. If both get into the same cell, you get various mixes created and sometimes a mixture will turn out to be a better virus than either parent.
This virus looks like a combination of apparently unrelated viruses. See https://theconversation.com/coronavirus-origins-genome-analy... for confirmation. That happens to be something that can happen either naturally or artificially.
Where conspiracy theorists get going is that a few years ago there were papers from the lab near Wuhan suggesting that a combination much like COVID-19's actual combination should be particularly effective in humans. So this looks like an extension of a known line of research from a lab involved in military work. Combine that with the local coverup and you can see how people go down the rabbit hole.
There's a rational reason to study this one, since SARS (1.0) was a big deal in the early 2000's, and anyway why wouldn't you study something you don't fully understand as a matter of course. It's not a stretch if it was found that it leaked from the lab by accident and a cover-up ensued.
Yes.
> your comment is worthless otherwise.
No.
I would discount the possibility that this was bioweapons research - the US was funding serial passage and gain-of-function research at this lab, of which the express purpose is to make viruses more infectious in different species, including humans.
At any rate, I don't think we can expect anything to be definitively proven. It is absolutely possible that this came out of the wild. But as the NY Magazine "Lab Leak" article illustrates, we should probably be open to the idea it came out of a lab. I also think we should reconsider whether or not serial-passage and gain-of-function research is something that can be ethically conducted. Anywhere.
See https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4797993/ for one of their previous lines of research that look similar to the actual COVID-19 virus.
Occam's Razor says the only (non-vet) BSL4 lab in China, studying bat coronaviruses, several miles from known first virus reports, that has had multiple previous virus leaks, with huge information shutdown by China for a year, is the more plausible culprit.
Earlier in March, Zhao Lijian, an outspoken Chinese diplomat, raised a suspicion on his personal Twitter account that it might have been the US army representatives to the Military World Games who brought the novel coronavirus to Wuhan in October 2019, after a top US health official admitted detecting coronavirus infections on some deceased flu patients. Zhao urged the US to disclose further information, exercise transparency on coronavirus cases and provide an explanation to the public.
But, there is more than one conspiracy theory here. And probably will be forever. As a hopefully rational third party, I would like it investigated.
But I'm currently giving good odds to "accidental release from program intended to research possible future pandemics". And if that winds up seeming at all likely, I believe that the whole world should commit to having better controls on this type of research to avoid future accidental releases. Because accidental mass murder isn't OK.
Why wouldn’t CCP stop all suspicion on this and say the virus originated in another part of China? It almost feels like a murderer trying to use reverse psychology by hiding in plain sight. Like, it can’t be from Wuhan Lab because they actually reported that it came from Wuhan (what idiot that’s trying to cover it up do that?). A calculated person would make such a calculation.
The truth might be weird here.
Given that the CDC and commercial companies were doing research in that lab, is the US just as culpable as China?
What was the reason for the CDC working with that lab? Aside from rationalizations, was it essentially just outsourcing the dirty work like any other polluting industry?
