Wait- that's all stuff from Pekar 2022, the paper with enormous math errors that you just said was irrelevant. When those errors are fixed, its 2-spill probability becomes low, which undercuts its whole story. Tho P(other zoo stories) is unaffected by market-story errors.

By that token anything by anyone who cites anything by any of the 29 authors of Pekar et al. 2022 would have to be presumed false. Let's stick to the specific points. Here the only relevant one is whether leaving RE sites in eases making a series of partial new clones.

Dinosaurs were thriving until asteroid struck, research suggests Dating of rock formation in New Mexico casts doubt on theory that species was already in decline Dinosaurs would not have become extinct had it not been for a catastrophic asteroid strike, researchers have said, challenging the idea the animals were already in decline. About 66m years ago, during the late Cretaceous period, a huge space rock crashed into Earth, triggering a mass extinction that wiped out all dinosaurs except birds. However, some experts have argued the dinosaurs were already in decline. Continue reading...

It's icky although the implications are hardly any worse than those for AI (mass unemployment, potential extinction).

The Covid β€˜lab leak’ theory isn’t just a rightwing conspiracy – pretending that’s the case is bad for science | Jane Qiu While figures like Steve Bannon have exploited the issue, scientists have done themselves no favours by shutting down legitimate inquiry, says award-winning science writer Jane Qiu

Jane Qui wrote recently about how a lack of transparency and overconfident conclusions in relation to the origin of COVID-19 has undermined trust in science.

The corrections to the Pekar 2022 Science paper claiming multiple SARS-CoV-2 introductions are factorizable and simple, using data contained in the paper and minimal assumptions. Their data and model imply that a single introduction was more likely.

"Here I show that after correcting a fundamental error in Bayesian reasoning [by Pekar et al] the results in that paper give larger likelihood for a single introduction than for two."

I'm at #datajconf in Athens this week and one very cool thing we've done is take a tour of the library of Journalists' Union of Athens Daily Newspapers, where they've kept a history of Greek news outlets. This is one of the oldest prints they have of, I believe, a paper called Neos Aristophanes.

What you just wrote is untrue, in many dimensions. Anyone who thinks the origins debate is settled in favor of zoonosis on the basis of current evidence is not attending to the evidence.

Inspection of the calculat...

The author who identified a coding error in Pekar et al (2022) has found a major statistical inference error too. Pekar et al appear to have applied stricter conditions for single spillover than for double spillover. Once corrected the Bayes factor favors single spillover.

Indeed. One argument for Huanan Seafood Market origin is a phylogenetic analysis suggesting dual lineages (A/B) spilled there. However, Jesse Bloom shows the tree can't be rooted reliably due to biased and incomplete data.
