He also said "the viruses studied under the NIH grant are evolutionarily, or phylogenetically (a big word), so distant from SARS-CoV-2 that there's no chance in the world that someone could make that virus turn into SARS-CoV-2."

" Her research also shot down a popular theory early in the pandemic that the virus was unleashed on the world via the Huanan Seafood Market in Wuhan — where exotic game was being sold for human consumption. This theory, Chan says, “is not supported by strong evidence,” noting it’s likely the outbreak at the market likely occurred after the virus was already passing between humans."
She might have missed these, cuz they weren't guest essays in the fake, or is it the failing, NY Times.

Surveillance of SARS-CoV-2 at the Huanan Seafood Market
Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019, emerged in December 2019. Its origins remain uncertain. It has been reported that a number of the early human cases of coronavirus disease 2019 had a history of contact with the Huanan Seafood Market. Here we present the results of surveillance for SARS-CoV-2 within the market. From 1 January 2020, after closure of the market, 923 samples were collected from the environment. From 18 January, 457 samples were collected from 18 species of animal, comprising unsold contents of refrigerators and freezers, swabs from stray animals and the contents of a fish tank. Using quantitative real-time polymerase chain reaction (RT-qPCR) and high-throughput sequencing (Bowtie2 analysis), SARS-CoV-2 was detected in 74 (70 RT-qPCR and 4 Bowtie2) environmental samples, but none of the animal samples. Three live viruses were successfully isolated. The viruses from the market shared a nucleotide identity of 99.99% to 100% with the human isolate HCoV-19/Wuhan/IVDC-HB-01/2019. SARS-CoV-2 lineage A (8782T and 28144C) was found in an environmental sample. RNA-sequencing analysis of SARS-CoV-2-positive and SARS-CoV-2-negative environmental samples showed an abundance of different vertebrate genera at the market. In summary, this study provides information about the distribution and prevalence of SARS-CoV-2 in the Huanan Seafood Market during the early stages of the outbreak of coronavirus disease 2019.

Pandemic start point is Wuhan seafood market, according to new studies : Goats and Soda : NPR
Updated July 27, 20221:33 PM ETOriginally published March 3, 20224:34 PM ET
This week, an international team of scientists published two extensive, peer-reviewed papers in Science, offering the strongest evidence to date that the COVID-19 pandemic originated in animals at a market in Wuhan, China. Specifically, they conclude that the coronavirus most likely jumped from a caged wild animal into people at the Huanan Seafood Wholesale Market, where a huge COVID-19 outbreak began in December 2019.....
Scientists who weren't involved in the research papers have called the new data " very convincing" and a " blow" to the lab-leak theory — that the virus somehow escaped from the Wuhan Institute of Virology, which does research on coronaviruses. In reaction to the papers, they say the data tips the scales toward wildlife sold at the market.
"The studies don't exclude other hypotheses entirely," says virologist Jeremy Kamil, who's at Louisiana State University Health Shreveport and was not involved in this research. "But they absolutely are pushing it toward an animal origin."
Neither of the papers provides the smoking gun — that is, an animal infected with the SARS-CoV-2 coronavirus at a market.
But they come close. They provide photographic evidence of wild animals, which can be infected with and shed SARS-CoV-2, sitting in the market in late 2019 — such as raccoon dogs and a red fox. What's more, the caged animals are shown in or near a stall where scientists found SARS-CoV-2 virus on a number of surfaces, including on cages, carts and machines that process animals after they are slaughtered at the market.
The new data paints an incredibly detailed picture of the early days of the pandemic. Photographic and genetic data pinpoint a specific stall at the market where the coronavirus likely was transmitted from an animal into people. And a new genetic analysis estimates the time, within weeks, when not just one but two spillovers occurred. It predicts the coronavirus jumped into people once in late November or early December and then again few weeks later. |
