      8. Continuing: “Our study rejects the hypothesis of emergence as a result of a recent recombination event.”—> I.e. the authors also conclude that the new #coronavirus did not originate from random recent admixture between different coronaviruses. Other possibilities of course.

      9. BOTTOMLINE: 1) Seafood market not the source. 2) This RNA #coronavirus mutates really fast. 3) 🧬 has unusual middle segment never seen before in any coronavirus. 4) Not from recent mixing. 5) That mystery middle segment encodes protein responsible for entry into host cells.

      10. TO BE CLEAR: I am absolutely not saying it’s bioengineering, nor am I supporting any conspiracy theories with no evidence. I’m simply saying scientists need to do more research + get more data. And finding the origin of the virus is an important research priority. Goodnight😴pic.twitter.com/N4Yp2H8Tst

      11. Dubbing this the [GENETIC THREAD] 🧬 thread, let’s delve back into the genetic similarities of the new 🦠 with SARS and bat #coronaviruses. Study in Lancet says ~88% related to closest bat coronavirus, 79% to SARS (which is more than humans-elephants) https://marlin-prod.literatumonline.com/pb-assets/Lancet/pdfs/S0140673620302518.pdf …pic.twitter.com/2568DtbsoJ

      13. For the most part, the new #coronavirus shares 87-88% overlap with bat coronavirus. But there are parts of it like the “S” gene 🧬 region where I drops to ~70%, and even 68% in lowest point. But other gene regions share 🧬 consensus as high as 95%.pic.twitter.com/XrIQOfgSOQ

      14. What is in the “S” 🧬 region of the #coronavirus? According to the Lancet piece (link 🧵 above), it encodes the virus envelop spike protein of the 🦠 for binding receptors of host cells - “crucial for host tropism” — which basically identifies how to target 🎯 host tissue.pic.twitter.com/rtqjDrtRgw

      15. One source or many sources? The mutation rate suggests the 2019-nCoV came from just one recent source in single jump (as opposed to several mutation sources). This doesn’t mean much other than it wasn’t several strains that started outbreak. Don’t over-interpret. Just FYI.pic.twitter.com/utEN7O4krg

      30) Dear friends, after learning that the original authors have formally retracted yesterday’s “uncanny” titled pre-print article, I believe it is prudent to delete the earlier posts 16-24 pertaining to it. Public health science has never been challenged by both such a fast...

      32) This is why it is important to never rush to conclusions and judgement on pre-print articles that aren’t peer reviewed. Even peer reviewed papers are sometimes flawed too, but hence why the need for replication of work by others to further confirm/refute. Normally all this...
