Leading biologist dampens his ‘smoking gun’ Covid lab leak theory. Nobel laureate David Baltimore says he overstated case, and the origins of the virus are still unknown.

This is correct. There is no “smoking gun” and no direct evidence that a lab leak led to Covid. The evidence is only circumstantial. And sure, it’s certainly possible a hugely-improbable series of events resulted in a virus with no known local animal host to somehow independently become unleashed outside of the lab studying those very viruses, and where known GoF research was being conducted.

But you know, I would not bet that way at all. Not at all.
