Role in Evolution
Viruses are an important natural means of transferring genes between different species, which increases genetic diversity and drives evolution. It is thought that viruses played a central role in the early evolution, before the diversification of bacteria, archaea and eukaryotes and at the time of the last universal common ancestor of life on Earth. Viruses are still one of the largest reservoirs of unexplored genetic diversity on Earth.

Famous quotes containing the words role in, role and/or evolution:
“My role in society, or any artist or poets role, is to try and express what we all feel. Not to tell people how to feel. Not as a preacher, not as a leader, but as a reflection of us all.”

“The trouble is that the expression material thing is functioning already, from the very beginning, simply as a foil for sense-datum; it is not here given, and is never given, any other role to play, and apart from this consideration it would surely never have occurred to anybody to try to represent as some single kind of things the things which the ordinary man says that he perceives.”
—J.L. (John Langshaw)
“The evolution of sense is, in a sense, the evolution of nonsense.”
