<< The key point about Freeman Dyson's book is that he is making the case for
life having a metabolic origin, rather than having an origin as a template
replicating molecule.  >>


I've been saying it loud and clear
that life is a REACTION to the heat cycle. It is that which can adapt to a heat
cycle.

This led to novel ways of chemicals surviving the heat cycle - two of which are
replication (the heat denatures and anneals like nucleotides) and metabolism
(using the sun's forced  heat for work. They are two sides of the same coin.

Dyson isn't going far enough.
No other origin idea makes sense.
Life is no independent creation that then adapts. That is nonsense.

Life is that non random cyclic chemical system based on the non random cyclical
heat cycle of the sun

Life is the echo not the voice.
