The numerical fitnesses of species defined in the Bak-Sneppen model of self-organized criticality are interpreted as binary strings. This allows new species to be generated by mutation of survivors. It is shown that selection in Bak-Sneppen systems defined on both uniform and random lattices produces genotypes in conformity with the Eigen criterion for the accumulation of genetic information in macromolecular sequences.
