A recently published document reveals "smoking gun" evidence of COVID-19's lab-based origin, according to Richard Ebright, a microbiologist at Rutgers and one of the earliest proponents of the lab leak hypothesis.
Ebright is referring to an invoice that shows an order for a particular enzyme that he believes scientists used to stitch together the genome for SARS-CoV-2, the virus that causes COVID-19. However, Alina Chan, a microbiologist affiliated with MIT and Harvard and co-author of Viral: The Search for the Origin of COVID-19, says that because the documents in questions are from early 2018, they do not constitute direct evidence, meaning there still "isn't enough to say a lab accident happened beyond reasonable doubt."
