Scientists discover novel virus that may shed light on viral evolution

Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a virus lacks the proper tools to infect an organism? How can it propagate?
