BREAKING: Multinational team uses 3 different methods to determine where #SARSCoV2 came from: each leads to horseshoe bats found widely in Asia. The virus now causing a human #pandemic has been in bats "for decades," only now reaching people.

Evolutionary origins of the SARS-CoV-2 sarbecovirus lineage responsible for the COVID-19 pandemic

In this manuscript, the authors address evolutionary questions on the emergence of SARS-CoV-2. They find that SARS-CoV-2 is not a recombinant of any sarbecoviruses detected to date, and that the bat...

Big implications from this peer-reviewed paper.
First, #COVID19 is not caused by a "China virus" that was "made in a Chinese lab," as some in the #Trump admin have claimed.
2nd, it may have jumped directly from a bat to a person, without intermediary animals.

3rd, The 2003 SARS has also been connected to Asian horseshoe bats, and these mammals may carry many types of #coronaviruses.
4th, this shows "how difficult it will be to identify viruses with potential to cause major human outbreaks before they emerge."
Worth revisiting, in light of this, the @sciencecohen recent paper about Shi Zhengli -- China's "Bat Lady" -- who has been accused by Sec. of State Mike #Pompeo & others in #Trump admin of starting the epidemic with viruses in her Wuhan lab. https://www.sciencemag.org/news/2020/07/trump-owes-us-apology-chinese-scientist-center-covid-19-origin-theories-speaks-out

While the new @nature paper leaves unresolved the potential role of #pangolins as intermediaries, for #SARSCoV2 from bats-to-people, the researchers say the animals were not necessary to spark the current human catastrophe. The virus comes from a viral group in bats that...

(continued) ...have a genetic characteristic that, "facilitated its jump to humans and may do so again," the scientists write, meaning SARS(2003) and #SARSCoV2 may be followed in the future by other #pandemic - potential viruses carried by horseshoe bats in Asia.
