In our system (DEME, breeding A-Life species complex Stigmatiocon cornigera; DEMEV, S. mundana; DEME(W), S. fenestris), the rules are derived from three fundamental dynamical principles, (1) individuals reproduce through bisexual interbreeding, (2) combinations of character states affect success or failure of the mating, and (3) the character states are inherited, but mutation may break out accidentally. The "biological concept of the species" is fully adoptable to these kinds of A-Lives. We can identify or discriminate individuals to the species observing the concept (definition) of species.
The system emarges well-nigh every species phenomena, the unity of species, the transition among generations, character differentiation in local populations of the species, formation of cline, allo- and parapatric speciation and hybrid zone. When the concept of "niche" is appended in the system (ECDM, S. macacobia), the sympatric speciation and the secondaly sympatricity were observed. Note that the concept of "adaptation" is not assigned in the both systems at all.
