  We dwell upon the physicist's conception of `life' since Schroedinger and
Wigner through to the modern-day language of living systems in the light of
quantum information. We discuss some basic features of a living system such as
ordinary replication and evolution in terms of quantum bio-information. We also
discuss the principle of no-culling of living replicas. We show that in a
collection of identical species there can be no entanglement between one of the
mutated copies and the rest of the species in a closed universe. Even though
these discussions revolve around `artificial life' they may still be applicable
in real biological systems under suitable conditions.
