| Since the start of the pandemic, authorities have primarily promoted a [[SARS-CoV-2:origins]] theory of zoonotic transfer from an animal host to humans. A group of researchers going by the name [[:D.R.A.S.T.I.C.]] has sought to counter what they consider a propaganda campaign by government, military, and industry to make it appear that the origins of SARS-CoV-2 are zoonotic. | Since the start of the pandemic, authorities have primarily promoted a [[SARS-CoV-2:origins]] theory of [[:zoonosis|zoonotic]] transfer from an animal host to humans.

| SARS-CoV-2 is most highly similar to coronaviruses that have been found in bats. | With the notable except of the spike protein, the genetric sequence that makes up SARS-CoV-2 is most highly similar to those of coronaviruses that have been found in bats. |

| | In 2015, scientists including [[:Ralph Baric]] and [[:Shi Zhengli]] published a paper noting the existence of SARS-like coronaviruses showing "potential for human emergence".((November 9, 2015 | Vineet Menachery et al | Nature Medicine | A SARS-like cluster of circulating bat coronaviruses |

| The [[:RaTG13]] [[:betacoronavirus]] is the most highly similar coronavirus to SARS-CoV-2, sharing 98.7% identical mitochondrial [[:rRNA]], but was supposedly generated from a bat fecal swab, which strikes some scientists as unlikely since metagenomic analysis shows a small 10.3% bacterial rRNA in the dataset.((November 22, 2021 | Steven E Massey | preprint | [[https://arxiv.org/abs/2111.09469|arXiv:2111.09469]])) | The [[:RaTG13]] [[:betacoronavirus]] is the most highly similar coronavirus to SARS-CoV-2, sharing 98.7% identical mitochondrial [[:rRNA]], but was supposedly generated from a bat fecal swab, which strikes some scientists as unlikely since metagenomic analysis shows a small 10.3% bacterial rRNA in the dataset.((November 22, 2021 | Steven E Massey | preprint | [[https://arxiv.org/abs/2111.09469|arXiv:2111.09469]])) |
