I know DNA gives instructions for proteins, but is it information as in the sense that it was created by a conscious mind? What about biologists who say that DNA is information?
DNA (deoxyribonucleic acid)
The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases adenine (A), guanine (G), cytosine (C), and thymine (T). In nature, base pairs form only between A and T and between G and C; thus the base sequence of each single strand can be deduced from that of its partner.
Ok, there is matter and there is energy. But you can't describe a system by just matter and energy, because several different arrangements of matter ad energy can all have the same total matter/energy but function completely different as a function of the geometry (arrangement) of the matter and energy.
That is what information is.
Increasing complexity can arise out of a system as long as global entropy increases as well.Kevin Kelly discussed the nature of information in his blog recently and reported a conversation with Freeman Dyson on the subject . See http://www.kk.org/thetechnium/archives/2011/04/infinite_order.php - Infinite Order in All Directions.
There seems to be a contradiction between the observed increasing complex structures we see in the Universe in galaxies and life forms and the second law of thermodynamics which demands increasing disorder.
Hope this helps G
No, we don't.We see information (the codified form created by humans) to always come from intelligence.
The premise is flawed, therefore the logical inference is flawed.could we, by strong inference, say that DNA is also from an intelligence?
This is definitely a tricky issue because "information" has two orthogonal meanings. One is about the physically countable - the bits, the microstates. The atomistic entities that would compose a more global state of order or disorder. And the other actually is about meaning - information as knowledge or regulation or constraint. And DNA embodies both these senses of the word.But there's more narrow definition about codifying sequences of events. Wiki has a defintion: "any kind of event that affects the state of a dynamic system." but I'm not sure it needs to affects a dynamic system.
What's been bugging me is that I cannot find an example of information (in the codified instructions sense) that does not involve life.
