Words in a book are also Shannon information but with an encoded message. If you think there is a message encoded in the Shannon information of DNA then why don't you decode it and tell us what it is.well I honestly don't know what you don't know
you surely recognize that DNA contains information, (in a quaternary (v binary) code) right?
'specified' or 'specifying' or 'functional' information merely differentiates between information which specifies something v Shannon information which does not- e.g. words in a book v radio static.
What SETI is actually looking for is a narrow-band microwave signal of a kind not thought to be produced naturally--evidence of design.To use an entirely secular example:
SETI searches Shannon information for the existence of specified information, it considers the latter such a strong objective indicator of the presence of intelligence, that a sequence of merely 6 (I think) anomalous amplitudes was enough to write 'WOW' in the margin.
I would argue that DNA is a tad more compelling than that -
