Question: is it possible to experiment how a virus forms and evolve

Danielle Nader answered on 9 Feb 2022:

Yes, but that is more of a specialist field for evolutionary virologists. Essentially they study the sequence of one virus and compare it to other viruses in that same family. This helps to classify the virus into distinct genera. Once you know which viruses are in the same genus, you can study the actual small changes in their genomic and proteomic structures. Bioinformaticians can also help in understanding what these changes mean in terms of phenotypic outcome i.e. some mutations increase the viral replication, some increase viral affinity for receptors, etc.
