What is a good evolutionary definition of life?
From an evolutionary perspective, life is defined as a set of randomly varying, self-replicating entities that: temporarily reverse (but do not violate) the law of increasing entropy of a system, because they have continual energy input; are in both thermal and chemical disequilibrium; compete among themselves for finite resources; and survive and reproduce in a non-random way that is strongly correlated with their fitness relative to their environment.
