They're still several decades of evolution away, given how fast viruses mutate in the wild. > We confirm that a direct proximal ancestor to SARS-CoV-2 is yet to be sampled, since the closest relative shared a common ancestor with SARS-CoV-2 approximately 40 years ago https://www.biorxiv.org/content/10.1101/2021.01.22.427830v3 https://www.biorxiv.org/content/10.1101/2021.01.22.427830v3 And do you have any idea how many animals there are in China? There's 1.4 billion people to start with. There's 100 to 100,000 more vertebrates than people in the world. Take even 50,000 samples and you're still barely scraping the surface.
