 The language of “codes” and “information” flows easily enough with respect to replication [see the entry  biological information].  Transcription, translation, punctuation, redundancy, synonymy, editing, proofreading, errors, repairing of errors, messages, copies, and information all sound natural enough. Yet, the literature dealing with information is both extensive and factious. Several different formal analyses of information can be found and very little agreement about which analysis is best for which subjects. On one point, these scholars tend to agree—cybernetic information and communication-theoretic information will not do for replication in biological contexts. Some argue for semantic information (Godfrey-Smith 2000a; Sarkar 2000; Sterelny 2000b). The trouble is that no widely accepted version of semantic information exists. Winnie (2000) distinguishes between Classical and Algorithmic Information Theory and opts for a revised version of the Algorithmic Theory. But, once again, the problem is that no such formal analysis currently exists.
