Newly obtained emails offer glimpses into how a narrative of certainty developed about the natural origins of the novel coronavirus SARS-CoV-2, while key scientific questions remained. The internal discussions and an early draft of a scientists' letter show experts discussing gaps in knowledge and unanswered questions about lab origin, even as some sought to tamp down on "fringe" theories about the possibility the virus came from a lab.

Influential scientists and many news outlets have described the evidence as "overwhelming" that the virus originated in wildlife, not from a lab. However, a year after the first reported cases of SARS-CoV-2 in the Chinese city of Wuhan, little is known how or where the virus originated. Understanding the origins of SARS-CoV-2, which causes the disease COVID-19, may be crucial to preventing the next pandemic.

The emails of coronavirus expert Professor Ralph Baric - obtained through a public records request by U.S. Right to Know - show conversations between National Academy of Sciences (NAS) representatives, and experts in biosecurity and infectious diseases from U.S. universities and the EcoHealth Alliance.

On Feb. 3, the White House Office of Science and Technology Policy (OSTP) asked the National Academies of Sciences, Engineering and Medicine (NASEM) to "convene meeting of experts… to assess what data, information and samples are needed to address the unknowns, in order to understand the evolutionary origins of 2019-nCoV, and more effectively respond to both the outbreak and any resulting misinformation."
