A major new Australian study of COVID-19 has found that it seems specially adapted to infect human cells https://www.newsmax.com/scitech/covid-19-study-australia-human-cells/2020/05/16/id/967713/

4-29-20 Professor Nikolai Petrovsky of Flinders University: you can force the bat virus to adapt to infect human cells via mutations in its spike protein, which would have the effect of increasing the strength of its binding to human ACE2, and inevitably reducing the strength of its binding to bat ACE2.
Viruses in prolonged culture will also develop other random mutations that do not affect its function. The result of these experiments is a virus that is highly virulent in humans but is sufficiently different that it no longer resembles the original bat virus. Because the mutations are acquired randomly by selection there is no signature of a human gene jockey, but this is clearly a virus still created by human intervention.
My group in collaboration with other Australian researchers have been using a modelling approach to study the possible evolutionary origins of COVID-19 by modelling interactions between its spike protein and a broad variety of ACE2 receptors from many animals and humans.
This work which we will publish on a prepress server next week shows that the strength of binding of COVID-19 to human ACE2 far exceeds the predicted strength of its binding to the ACE2 of any of the other species. This points to the virus having been selected for its high binding to human ACE2. In the absence of evidence of historic human infections with this virus, which could result in such selection, this either is a remarkable coincidence or a sign of human intervention.
This, plus the fact that no corresponding virus has been found to exist in nature, leads to the possibility that COVID-19 is a human-created virus. It is therefore entirely plausible that the virus was created in the biosecurity facility in Wuhan by selection on cells expressing human ACE2, a laboratory that was known to be cultivating exotic bat coronaviruses at the time. http://anthraxvaccine.blogspot.com/2020/04/theory-of-how-sars-coc-2-was-created-in.html
