WebKey points: Viruses undergo evolution and natural selection, just like cell-based life, and most of them evolve rapidly. When two viruses infect a cell at the same time, they may swap genetic material to make new, "mixed" viruses with unique properties. For example, flu strains can arise this way. WebEvolution is the theory that all the kinds of living things that exist today developed from earlier types. The differences between them resulted from changes that happened over many years. The simplest forms of life …
