Well done Kristian [to BBC] and Andrew [above}! Andrew's list is great - I don't see anything that points to active[cloning] or passive [cell or animal passage] lab manipulation however for balance we could put in some of Kristian's points above.

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

Jotting down some of the new stuff: Bill's potential source of the furin site - perhaps could dig into that more. Looks like SARS-CoV-2 can infect and readily transmit in mink (in the Netherlands). https://www.eurosurveillance.org/content/10.2807/1560-7917.ES.2020.25.23.2001005#html_fulltext - some severe disease too. Infects cats. So broad host range. Look into that press-release about infecting fruit bats (and cats). Recombination of RBD variable loop out of RaTG13 rather than in to SARS-CoV-2 from pangolins. Large variety of pangolin viruses (these are illegally imported from SE Asia - so where are they getting them from). Seems to readily loose furin site in cell culture. Really odd mutation patterns with lots of C->T and A->T, much higher NSyn/Syn ratio than you would expect? RmYN02 being closer in ORF1ab but recombines out in the rest - tell us something but not sure what just yet. Deletions in the accessory genes - suggests ORF7 & 8 maybe don't have much function in humans - somebatty thing?

We just resubmitted our revised MS on the 'distal' origin. I added a new figure to supplementary on the variable loop recombination: [shared file(s): image.png]

Shows better how the pangolin distance is exactly the same in the variable as the rest of the CTD whereas RaTG13jumps out.
