Did coronavirus leak from a lab?

Controversy, intrigue and RNA sequences

Could SARS-CoV-2, the virus behind COVID-19, have leaked from a lab? It’s a complicated story of science, ethics, not-quite-smoking guns and bat caves—so I printed out some coronavirus genetic sequences, and made a video to take a look at the evidence.

Many thanks to Tran Nguyen for her help with this video!
