It seems that you already agree that virus is a life form. The conundrum is:
does this make the virus alive? It seems to me, that this then degenerates
into a debate about what the word alive means. Certainly in its chemical form
a virus does not respire, eat, utilize ATP etc. therefore, in this state, it is
not alive. However, during the replication phase within a cell, the virus
could be thought to do all of these things rather efficiently. Viruses can
certainly respond to their environment and adapt through evolution. In fact,
they are much more efficient than other conventional life forms in such
processes. Your question takes us back to the very definition of what life is.
Certainly until the 1940s the definition of life would have included constant
growth and change. Viruses never grow, they replicate. By most measures, they
do not change, although certainly changes on a molecular level are quite
Are viruses alive? Things considered alive eat, grow, and divide. Viruses
don't do this so I guess they are not alive. Are viruses life forms? That
would seem to be obvious. Of course they are.
