There is currently zero evidence to support a zoonotic origin.
It took 9 months to find the source of MERS (camels). It took 14 months to find the origin of SARS1 (bats).
What evidence do you have that this was transmitted from an animal carrier? What mammal in China (it's not like there are that many mammal species living in the Wuhan metropolitan area) has been identified that easily catches COVID? The answer is zero.
The most likely explanation for this, which fits with all the other circumstantial data, is that the zoonotic origin was a genetically engineered mouse with human ACE2 receptors lining it's lungs. Note that I'm saying the mouse was genetically engineered, not the virus itself. The virus could easily evolve to infect humans by repeatedly exposing the humanized mice to the original, completely natural origin bat viruses.
Calling out "mental gymnastics" when you are acting as if it's a pure coincidence that a bat virus pandemic originated in a city containing the world's leading bat-borne virus research facility is the height of hypocrisy and cognitive dissonance. And before you say that the lab is in Wuhan because that's where the viruses are, no, it's not. The viruses historically have emerged in Yunnan province, in remote caves 1000 KM away from Wuhan.

- danenania 5y agoIf ebola had emerged right next to a lab doing high-risk research on ebola-like viruses, people would have (justifiably) been highly suspicious.

- tootie 5y agoYour "most likely" theory seems extremely fringe with absolutely zero evidence. I can see how it's possible but it seems vastly more complicated than just a lab leak.
- JPKab 5y agoZero evidence? Might want to look at the details of the NIH grant funding the research in the Wuhan Institute of Virology. You aren't very informed on the subject, which is why you dismiss it as fringe. https://reporter.nih.gov/search/xQW6UJmWfUuOV01ntGvLwQ/project-details/9491676 https://reporter.nih.gov/search/xQW6UJmWfUuOV01ntGvLwQ/proje... It's right at the bottom of the summary. "3. Test predictions of CoV inter-species transmission. Predictive models of host range (i.e. emergence potential) will be tested experimentally using reverse genetics, pseudovirus and receptor binding assays, and virus infection experiments across a range of cell cultures from different species and humanized mice." But sure, it's fringe and unlikely that the virus leaked out of a lab where it was specifically stated by the scientists applying for the grant that the funding would be used for testing interspecies transmission of bat coronaviruses with humanized mice. The lab doing this being in Wuhan, where the pandemic originated is also totally fringe and unlikely, is totally unrelated, right?
- tootie 5y agoRead this part of the thread again: https://twitter.com/MoNscience/status/1396243452099170305 https://twitter.com/MoNscience/status/1396243452099170305 Gain of function proponents are ignoring research that indicates it's not possible to generate a virus dangerous to humans without leaving specific telltales. While this study isn't necessarily conclusive or a door slam in the face of lab leak, it's pretty huge data point that makes it far less likely.
- JPKab 5y agoThis is a horrible Twitter thread. He leads off with an immediate ad hominem against Nicholas Wade, complete with an accusation of racism. He then states, falsely, that it isn't possible to engineer a virus without telltale markers, ignoring more modern techniques which don't leave telltales. He also conflates engineering a virus with the argument of it leaking. The thread reeks of cognitive dissonance and cherry picked straw men, but the disgusting racism smear on Wade was just wrong. And I'm not even going to dig into the out of the gate comparison he used with climate deniers. Deeply insulting, and in bad faith. I also forgot to mention that he deliberately ignored the humanized mice being the location of the serial passage work, and straw manned a "petri dish". Completely misrepresenting the fact that was most crucial. In the future, using a Twitter account with locked comments is inadvisable. He blocked comments for a reason.
