176:) dissociated into single-stranded polynucleotides and each of these acted as a template for synthesis of a complementary strand producing two double stranded copies. In a system such as this, individual duplex replicators with different nucleotide sequences could compete with each other for available mononucleotide resources, thus initiating natural selection for the most “fit” sequences. Replication of these early forms of life was likely highly inaccurate producing mutations that influenced the folding state of the polynucleotides, thus affecting the propensities for strand association (promoting stability) and disassociation (allowing genome replication). The evolution of order in living systems has been proposed to be an example of a fundamental order generating principle that also applies to physical systems.

boundary into the crystalline form. Crystals may have irregularities where the regular atomic structure is broken, and when crystals grow, these irregularities may propagate, creating a form of self-replication of crystal irregularities. Because these irregularities may affect the probability of a crystal breaking apart to form new crystals, crystals with such irregularities could even be considered to undergo evolutionary development.
