Fossil viruses preserved in hot spring bacteria

Fossilized microbes have provided scientists many clues about origins of life. By comparison, little attention is given to viruses in the fossil record. Although technically non-living, there is no question these tiny packets of protein-sheathed DNA have shaped the evolution of most life on earth, including humans. But can viral particles, a fractional size of even the smallest bacteria, actually become fossils? A study recently published in the journal Geobiology argues they can. Here, scientists present the first experimental evidence of silicification- the encasement in silicate minerals- of viruses living in hot spring biofilms. Moreover, these viruses can become fossils while still inside their host cells.
