The question of where Covid-19 came from has become one of the most contentious and heated topics. Even the US intelligence community is split between those who believe it most likely emerged naturally from the wild and those who believe it came from a lab, the Wuhan Institute of Virology.

This is a conversation about where the evidence points between Yuri Deigin of the DRASTIC collective that has been researching the lab, and Stuart Neil, a virology professor at Kings College in the UK.

There is a fair amount of technical detail in this conversation, which is being released unedited. To help the more casual viewer we have listed relevant timecodes to the more accessible parts of the dialogue.
