Answer
To be evolutionarily independent means that species can be defined by the smallest evolutionary independent unit. When a species is referred to as being independent, this means that their selections, mutations, drifts, and gene flows occur in separate populations. The change in allele frequencies occurs independently across separate species. Species form a boundary to allow the spread of alleles to other species.
