Dr. Fauci testified that, after examining the scientific data, most scientists have concluded that SARS-CoV-2 most likely emerged in humans as a zoonosis. The evidence supports the scenario that two distinct ancestral lineages of SARS-CoV-2 jumped from animals into humans, and that the Huanan Seafood Market in Hubei Provence, China, where wild animals were routinely present and slaughtered, was the epicenter of the pandemic. Importantly, Dr. Fauci acknowledged that he remains open to evidence supporting a lab leak if it were to become available. Indeed, all scientists must be open to this possibility. Factoring in new data that are sound and validated, even if a prevailing hypothesis were contradicted, is an essential aspect of scientific training. A critical guiding principle of science is that knowledge is continually revised and updated based on quality new evidence.
