- Reposted by Brendan J. KellyI am fascinated by how viruses evolve - and not just since #SARSCoV2 has shown us at the global stage how consequential virus evolution can be for us. In my new story in @science.org I got to explore how researchers are probing deeper into the past with old RNA virus genome. So a 🧪 thread…
