In the earliest part of my reporting on the subject, I was alarmed to see that scientists, including Dr. Ralph Baric of the University of North Carolina and Dr. Shi Zhengli of the Wuhan Institute of Virology, were conducting experiments on coronaviruses, including SARS viral strains, that would make the resulting modified viruses more deadly. It was found that these lab-created SARS mutants were most effective on “human airway epithelial cells”. These cells line the inside of the upper airway of humans.
To the point of almost bragging, many scientists who conducted this type of research seemed rather impressed with themselves for being able to accomplish such a feat. It was also interesting that, oftentimes, these laboratory mutated viruses had little effect on other human cellular material.
Now, it appears that a team of Australian scientists has confirmed the same about the SARS-CoV-2 virus, the virus responsible for the COVID-19 outbreak.
From the Daily Telegraph:
A team of Australian researchers have published a scientific paper proving that the SARS-CoV-2 coronavirus appears to be best adapted to attack human cells, raising even more questions about the pandemic’s origins.
The scientists from Flinders University and La Trobe used powerful computers to model the protein receptors in a number of animal species to see how the coronavirus’s spike protein attached itself to them.
During that analysis, the scientists determined that the virus did not make the jump from bat to human, absent a yet-to-be-determined intermediate species or a man-forced mutation in a laboratory. This data should put to end the “bat soup” theory pushed by Wuhan Lab defenders, as such a jump from bats to humans is highly unlikely. Considering that another intermediate species has not been identified, it again opens the door to the possibility that this originated that the lab.
“Hence, if the virus has a natural source, it could only have come to humans via an intermediary species which has yet to be found,” [Professor Nikolai Petrovsky] said.
While the researchers also found that the coronavirus could attach relatively easily to pangolins, as well as domestic animals like cats and dogs,
