Hello, I've been seeing following image circulated online. I was wondering what you make of this since I'm not an expert.
The claim is that the protein envelope (for example: https://www.ncbi.nlm.nih.gov/protein/1791269092 ; only 75bp) is 100% the exact same sequence as the envelope of Bat-SARS. And that this shouldn't be possible (or highly unlikely) to remain exactly the same after a natural mutation.
What do you make of this? Thanks in advance and sorry for posting this in the wrong place. You can delete this later.
