Cellular life is immersed into an ocean of viruses. Virosphere forms the shadow of this cell-based tree of life: completely dependent on the tree for existence, yet, the tree is equally unable to escape its ever evolving companion. How important role has the shadow played in the evolution of life? Is it a mere ethereal partner or a constitutive factor? In this chapter four puzzles in virus research are taken under the scope in order to probe some of the intriguing ways by which viruses can help us understand life on Earth. These puzzles consider the origin of genetic information in viruses, viruses as symbiotic partners, the structural diversity of viruses and the role of viruses in the ori…
