Conspiracy theories regarding genetically engineered viruses don't do well here.

  You should understand what Serial Passage and Gain of Function is. It's using natural selection in a lab and not easily detected. It was also a type of research that was being done at that lab. The paper addresses Serial Passage in the last part.

  Much work has been done on genetically engineering viruses and that includes coronoviruses. We certainly know very well how to do it for one purpose or another. This is a fact not a theory. Currently it's impossible to say Covid-19 resulted, maybe in part, from this activity or not. Terrible not to know something for a fact but that's how it is. Call a particular view a conspiracy theory if you like but that's just rhetoric and takes us not a step further towards a definitive answer.
