A fun and lightweight 10-minute (very basic, but highly-accessible) primer into the mechanisms by which new viruses appear to emerge via spillover infection and viral evolution. I was pleased by the accuracy of the animations including efforts to show relative scale of microorganisms and the (correct) illustration of RNA as the genetic material of a coronavirus (many illustrators draw all viruses as carrying a double-stranded DNA payload).
