How does information theory shed light on the origin of human life, if at all?

  • the role of information theory is still debatable though research is on

    according to the book “Information Theory, Evolution, and The Origin of Life”

    Information, transcription, translation, code, redundancy, synonymous, messenger, editing, and proofreading are all appropriate terms in biology. They take their meaning from information theory (Shannon, 1948) and are not synonyms, metaphors, or analogies.

    The genome is sometimes called a “blueprint” by people who have never seen a blueprint. Blueprints, no longer used, were two-dimensional, a poor metaphor indeed, for the linear and digital sequence of nucleotides in the genome. The linear structure of DNA and mRNA is often referred to as a template. A template is two-dimensional, it is not subject to mutations, nor can it reproduce itself. This is a poor metaphor as anyone who has used a jigsaw will be aware. One must be careful not to make a play on words.

    the sequences of nucleotides or amino acids that carry a genetic message have explicit specificity. (Otherwise how does the organism live?) Now, in this book, the term information does not mean knowledge, although a message composed of a sequence of symbols may transfer knowledge to the receiver of the message.

    The genetic information system operates without regard for the significance or meaning of the message, because it must be capable of handling all genetic messages of all organisms, extinct and living, as well as those not yet evolved. It does not have to be “about something.”

    The genetic information system is the software of life and, like the symbols in a computer, it is purely symbolic and independent of its environment. Of course, the genetic message, when expressed as a sequence of symbols, is nonmaterial but must be recorded in matter or energy. We could, in principle, send the genome of a mosquito to our little green friends on an Earth-like planet somewhere in the Milky Way Galaxy.
