comment on GR Weekly of 2005-01-23
provoked me to clarify my worries on ‘Nature recycling us
completely’. No, it’s not about chemical elements and compounds.
It is about information content carried by our biochemical and
laws of physics must be consistent with the existence of human
thought and life itself. DNA is an information-storage medium, and
biological evolution, which generates new genes, is a form of
information processing. Genes could not evolve to fill ecological
niches if the problems set by the physics of sunlight, water and
gravity were not soluble by computations performed by quite
different physical systems, such as long-chain carbon molecules.
