Viruses may have been around since the evolution of the first living cells since creation; They are found where life exists, but their origin is unclear because they do not form fossils, so molecular techniques have been a very useful way to investigate how they arise. These techniques depend on the availability of ancient viral DNA and RNA, but unfortunately most of the viruses that have been preserved and stored in laboratories are less than 90 years old. Opinions differ about whether viruses are living organisms or only organic structures that interact with them. They have been described as...
Viruses may have been around since the evolution of the first living cells since creation; They are found where life exists, but their origin is unclear because they do not form fossils, so molecular techniques have been a very useful way to investigate how they arise. These techniques depend on the availability of ancient viral DNA and RNA, but unfortunately most of the viruses that have been preserved and stored in laboratories are less than 90 years old. Opinions differ about whether viruses are living organisms or only organic structures that interact with them. They have been described as organisms on the edge of life, since they resemble living organisms in that they have genes and evolve through natural selection.
