对病毒世界的缺乏描述阻碍了我们对病毒域的规模和多样性的理解。几乎所有的物种都可以被多种病毒感染。随着我们对病毒知识的增加，似乎这无数的病毒可能被组织成数量相当少的病毒谱系，包括感染属于不同生命领域的宿主的成员。属于一个谱系的病毒共享一个共同的先天“自我”，即病毒体的结构和组装原则。这个假设有一些后果。所有的病毒都是古老的，可能在细胞生命之前，病毒的起源是多系的，而不是细胞生命的单系起源。(C)2003年，Elsevier SAS科学与医学版。All rights reserved.
The scarce characterisation of the viral world has hampered our efforts to appreciate the magnitude and diversity of the viral domain. It appears that almost every species can be infected by a number of viruses. As our knowledge of viruses increases, it appears that this myriad of viruses may be organised into a reasonably low number of viral lineages including members infecting hosts belonging to different domains of life. Viruses belonging to a lineage share a common innate "self" that refers to structural and assembly principles of the virion. This hypothesis has a few consequences. All viruses are old, maybe preceding cellular life, and virus origins are polyphyletic, as opposed to the idea of a monophyletic origin of cellular life.
