Carl Woese suggested that biochemical properties evolve, which could
imply that biochemical properties are not the same throughout the
universe. On the other hand, I suppose the standard view is that
chemical and biochemical properties originated in the initial
conditions of universe and are the same throughout the universe, which
is consistent with the Copernican Principle and General Relativity.
Do you agree or disagree with Woese on the origin of chemical and
biochemical properties?
In what possible context did Woese suggest any such thing? Do you
have a citation? Could it really be simply that as the amino acid
sequence of proteins or the nucleotide sequence of nucleic acids
evolve then the properties of the macromolecules formed also changes?
The context is his 1967 book on the Genetic Code. And I clarify that I
do not know if he still holds to his 1967 view. But Woese proposed that
the "properties" of the genetic code evolved. This was his explanation
for the different genetic codes such as the nuclear genetic code and
the mitochondrial genetic code. Since then, articles showed that the
different codes resulted from the chemistry of the protoplasm. And I
never heard that Woese conceded to this, as far I know.
